9-5-2017 RONDA, ANDALUSIA - EURASIAN WREN (Troglodytes troglodytes)


The Eurasian wren (Troglodytes troglodytes) or northern wren is a very small insectivorous bird, and the only member of the wren family Troglodytidae found in Eurasia and Africa (Maghreb). In Anglophone Europe, it is commonly known simply as the wren. It has a very short tail which is often held erect, a short neck and a relatively long thin bill. It is russet brown above, paler buff-brown below and has a cream buff supercilium. The sexes are alike.


The species was once lumped with Troglodytes hiemalis of eastern North America and Troglodytes pacificus of western North America as the winter wren. The Eurasian wren occurs in Europe and across the Palearctic – including a belt of Asia from northern Iran and Afghanistan across to Japan. It is migratory in only the northern parts of its range. It is also highly polygynous, an unusual mating system for passerines.


The Eurasian wren was described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Motacilla troglodytes. The specific epithet is from the Ancient Greek trōglodutēs meaning "cave-dweller". In 1555 the German naturalist Conrad Gessner had used the Latin name Passer troglodyte for the Eurasian wren in his Historiae animalium. The species is now placed in the genus Troglodytes that was introduced by the French ornithologist Louis Pierre Vieillot in 1809.


The Eurasian wren was formerly considered conspecific with two North American species: the winter wren (Troglodytes hiemalis) and the Pacific wren (Troglodytes pacificus). Some ornithologists place the Eurasian wren, the winter wren and the Pacific wren in a separate genus Nannus that was introduced by the Swedish naturalist Gustaf Johan Billberg in 1828 with the Eurasian wren as the type species.


Common but inconspicuous in woodland habitats with dense undergrowth, gardens, farmland hedgerows, heathland and coastal cliffs. It usually sings from a fairly exposed perch, but on other occasions it behaves like a mouse, moving between the brambles and undergrowth. It is easily identified by its small size, brown plumage, and the habit of keeping its tail elevated. It is heard more frequently than it is seen. The song is powerful and lively with a diverse series of repeating trills and chirps.

9-5-2017 RONDA, ANDALUSIA - EUROPEAN SERIN (MALE) (Serinus serinus)


The European serin, or simply the serin (Serinus serinus), is a diminutive member of the finch family, Fringillidae. This sprightly bird is the smallest within its family, closely related to the Atlantic canary. It is characterized by its short tail and a length that spans a mere 11 to 12 centimeters. The serin's plumage is a tapestry of nature's palette, with upper parts dappled in dark-streaked greyish green and a conspicuous yellow rump. The underparts are a canvas of yellow breast and white belly, both adorned with heavy streaks.

When attempting to identify the European serin, look for the male's radiant yellow face and breast, which stand out against the greenish backdrop of its feathers. The male also boasts yellow wing bars and yellow tail sides, which can be quite helpful in distinguishing it from similar species. Both sexes share a buzzing trill of a song that resonates through their Mediterranean habitats.


The European serin is partial to open woodland and cultivated areas, often with a sprinkling of conifers. These environments provide the perfect backdrop for breeding and foraging.

This species has a breeding range that extends across southern and central Europe and into North Africa. Populations along the southern and Atlantic coasts tend to be resident, while those in the north are migratory, seeking warmer climates in southern Europe during the winter months.

Outside of the breeding season, the European serin is a sociable creature, forming flocks that may sometimes mingle with other finch species. It is an active and often conspicuous bird, its presence easily announced by its distinctive trill.


The serin's song is a distinctive buzzing trill, a sound that becomes part of the ambient music in regions where these birds are common.

The European serin weaves its nest within the shelter of a shrub or tree, where it lays a clutch of 3 to 5 eggs. The chosen breeding habitats are often areas of open woodland and cultivation, with a preference for some conifers.

The diet of the European serin is predominantly seeds, but it does not shy away from including insects during the breeding season, providing essential protein for its young.

The IUCN Red List categorizes the European serin as Least Concern, indicating that, for now, this species does not face any imminent threats to its survival.

9-5-2017 RONDA, ANDALUSIA - COAL TIT (Periparus ater)


The Coal Tit, scientifically known as Periparus ater, is a diminutive passerine bird belonging to the tit family, Paridae. It is easily recognized by its large white nape spot set against a black head. The adult's glossy blue-black head, throat, and neck contrast with the off-white face and brilliant white nape. The underparts range from whitish to rufous on the flanks, and the bird's bill is a stark black.

To identify the Coal Tit, look for the distinctive white nape spot on its black head. The sides of the face may have a grey to yellow tinge, depending on the subspecies. The white tips of the wing coverts are visible as two wingbars. Juveniles are duller, lacking the glossy black head, and their white nape and cheeks are tinged with yellow.

The Coal Tit is not particularly habitat-specific but is typically found in temperate humid conifer forests. It can also be seen in a variety of wooded areas, including mixed forests and gardens.


This species is a widespread and common resident breeder throughout the temperate to subtropical Palearctic, including North Africa. It is mostly sedentary, with only local movements in response to severe weather.

Coal Tits are known for their acrobatic skills and restless activity. They often form small flocks with other tits during winter. Their foraging behavior is influenced by risk, and they are known to increase body mass in response to predator calls and adjust their mass gain based on food availability.

The Coal Tit's calls are short "dee" or "see-see" sounds, while its song is a strident "if-he, if-he, if-he," which is most frequently heard from January to June and in autumn. The song is similar to that of the Great Tit but is much faster and higher in pitch.

Nesting sites are varied, including holes in rotting tree stumps, ground burrows, and old nests of other large birds. The nest is made of moss, hair, and grass, with a lining of rabbit fur or feathers. The Coal Tit typically lays seven to eleven red-spotted white eggs, mainly in May, and usually breeds once per year.

The Coal Tit can be confused with other tit species, but its distinctive white nape spot and black head are key differentiators.

The diet consists of beechmast, seeds from fir and larch cones, and seeds from alders and birches. They also visit gardens to feed on sunflower seeds and other offerings.

1-4-2017 MIAMI, FLORIDA - GREAT HORNED OWL (Bubo virginianus)


The Great horned owl (Bubo virginianus) is a large owl native to the Americas. It is an extremely adaptable bird with a vast range and is the most widely distributed true owl in the Americas. The Great horned owl is one of the earliest nesting birds in North America, often laying eggs weeks or even months before other raptorial birds.

The Great horned owl is a round-faced bird with a distinctive horn-shaped feather tuft on the crown of its head, which is darker than the rest of its head, promoting the overall camouflage. The owl possesses powerful, solid legs, feet, and claws. The Great horned owl has binocular vision due to its eyes, facing forward. The eyes of the horned owl are various shades of yellow. This bird can also be distinguished by the white colored patch on its throat. Black and brown stripes extend all over the white underbelly. The bill of the bird is black, surrounded by white or tan colored plumage. The plumage on their back is darker, covered with brown and black markings.


This owl is native to the Americas with its range, covering the greater part of North America, stretching to Central America, and reaching South America. The Great horned owl occurs primarily in woodlands and open fields, scattered throughout its range. However, the species can also be found in mangroves, grasslands, swampy and marshy areas as well as deserts. In addition, this bird occasionally inhabits human settlements, found throughout rural and urban areas.


These birds are solitary animals, socializing only for nesting. They usually roost by day in protected places such as a tree limb or a recess in a rock. Great horned owls are efficient nighttime hunters, though they are known to hunt in the daytime as well. Horned owls are non-migratory, remaining within the same area throughout the year. Some individuals may become "territorial floaters", not having a certain territory and constantly traveling through territories of other owls. These birds use hooting as a form of communication. Through hooting, they can search for mates during the mating season as well as set up territorial dominance.

Great horned owls have a monogamous mating system and form long-lasting pair bonds. Typically, the mated pairs are territorial, driving away other pairs from their territory in order to have full access to prey. By the mating season, the birds begin hooting with increased intensity, looking for mates. Female owls hoot only during this period while males normally hoot all year round. Breeding season takes place from November to April. The mating pair finds a nest, which is usually one, abandoned by a squirrel or another bird, including a Great horned owl. The female may lay up to 6 eggs with an average of 2-3. Both parents take part in the incubation for 30-35 days. After hatching, both parents provide the chicks with food. Young fledge by 6-9 weeks old, becoming independent at the age of 5-10 weeks. Reproductive maturity is achieved between 1 and 3 years of age.

9-5-2017 RONDA, ANDALUSIA - BLUE ROCK THRUSH (MALE) (Monticola solitarius)


The blue rock thrush (Monticola solitarius) is a chat species, reminiscent of a thrush, with a starling-like stature, measuring 21–23 cm in length. The male of the nominate subspecies is predominantly blue-grey, save for darker wings, presenting a striking appearance. Females and immature birds are less vivid, with dark brown upperparts and paler, scaly brown underparts. The male of the subspecies M. s. philippensis is distinguished by rufous-chestnut plumage from the mid-breast to the undertail, a feature absent in both sexes of the rock thrush.

To identify the blue rock thrush, look for the male's unmistakable blue-grey plumage and the female's less conspicuous brown tones. The male M. s. philippensis can be recognized by its rufous-chestnut lower half. Both sexes lack the reddish outer tail feathers seen in rock thrushes.

This bird favors open, mountainous regions where it can nest in rock cavities and walls.


The blue rock thrush breeds across southern Europe, northwest Africa, and from Central Asia to northern China and Malaysia. It is a resident bird in Europe, north Africa, and southeast Asia, with some populations exhibiting altitudinal migration. Other Asian populations are migratory, wintering in sub-Saharan Africa, India, and southeast Asia. It is a rare visitor to northern and western Europe.

The blue rock thrush is an omnivore, consuming a varied diet of insects, small reptiles, berries, and seeds. It breeds in its preferred mountainous habitats, laying 3-5 eggs per clutch.

The male's song is a clear and melodious call, louder than that of the rock thrush, which can be heard echoing through its mountainous domain.

As an omnivore, the blue rock thrush has a diverse diet that includes insects, small reptiles, berries, and seeds.

The blue rock thrush is currently listed as Least Concern on the IUCN Red List, indicating that it is not at immediate risk of population decline.

8-5-2017 SEVILLE, ANDALUCIA - EURASIAN BLACKBIRD (MALE) (Turdus merula)


The Common blackbird (Turdus merula) is a species of true thrush. It is also called the Eurasian blackbird (especially in North America, to distinguish it from the unrelated New World blackbirds), or simply the blackbird where this does not lead to confusion with a similar-looking local species. This common and conspicuous species has given rise to a number of literary and cultural references, frequently related to its song.

The adult male has glossy black plumage, blackish-brown legs, a yellow eye ring, and an orange-yellow bill. The bill darkens somewhat in winter. The adult female is sooty-brown with a dull yellowish-brownish bill, a brownish-white throat, and some weak mottling on the breast. The juvenile is similar to the female but has pale spots on the upperparts, and the very young juvenile also has a speckled breast. Young birds vary in the shade of brown, with darker birds presumably males. The first-year male resembles the adult male but has a dark bill and weaker eye ring, and its folded wing is brown, rather than black like the body plumage.

23-3-2017 SAN GERARDO DE DOTA COSTA RICA - COLLARED TROGON (MALE) (Trogon collaris)


The collared trogon (Trogon collaris) is a near passerine bird in family Trogonidae, the quetzals and trogons. It is found in Mexico, throughout Central America, and in northern South America.

The collared trogon usually perches between the higher understory and the lower part of the canopy. It is usually seen singly or in pairs, but small groups may gather outside the breeding season.

The collared trogon eats small fruits (such as berries) and invertebrates such as caterpillars, crickets, cicadas, beetles, and phasmids. They often accompany the edges of mixed-species foraging flocks but do not mix with the other members.

8-5-2017 RONDA, ANDALUSIA - EUROPEAN STONECHAT (Saxicola rubicola)


The European stonechat, Saxicola rubicola, is a small, charming passerine bird, once thought to be a member of the thrush family but now placed within the Old World flycatcher family, Muscicapidae. This species exhibits a striking sexual dimorphism, with males donning a black plumage with vibrant orange throats and females wearing a more subdued brown.

Males in their summer plumage are unmistakable with their black heads, orange throats, and white bellies. They also sport a distinctive white half-collar and small white patches on the wings and rump. Females, on the other hand, are predominantly brown with less pronounced white wing patches. Both sexes have notably short wings, which are shorter than those of their migratory relatives.


The European stonechat favors heathlands, coastal dunes, and open grasslands dotted with shrubs, brambles, and heather. These habitats provide the perfect backdrop for their active foraging and breeding behaviors.

This species is widely distributed across Europe, reaching as far east as Ukraine and the South Caucasus, and can also be found in parts of North Africa.

Stonechats are known for their lively presence, often perching conspicuously as they keep a vigilant eye on their surroundings. They exhibit a partial migratory pattern, with some populations moving southward to escape the colder winters.

The male stonechat's song is a delightful, high-pitched twitter, reminiscent of a dunnock's melody. Both sexes communicate with a distinctive call that evokes the sound of two stones being tapped together.


European stonechats are monogamous during the breeding season and commence their reproductive efforts at one year of age. They raise two to three broods per season, with the female constructing the nest and both parents tending to the young.

The European stonechat can be confused with the Siberian stonechat and the African stonechat, but genetic evidence supports their distinction as separate species.

These birds are adept insectivores, gleaning a variety of invertebrates from their environment to sustain themselves and their offspring.

The European stonechat does not currently face any significant conservation threats and enjoys a stable population across its range.

8-5-2017 ARCOS DE FRONTERA, ANDALUSIA - BARN OWL (Tyto alba)


The Barn owl (Tyto alba) is the most widely distributed species of owl in the world and one of the most widespread of all species of birds. It is found almost everywhere in the world except for the polar and desert regions, Asia north of the Himalayas, most of Indonesia, and some Pacific Islands. This owl does not hoot but utters an eerie, drawn-out screech.

The Barn owl is a medium-sized, pale-colored bird with long wings and a short, squarish tail. Its head and upper body typically vary between pale brown and some shade of grey in most subspecies. Some are purer, richer brown instead, and all have fine black-and-white speckles except on the remiges and rectrices (main wing and tail feathers), which are light brown with darker bands. The heart-shaped face is usually bright white, but in some subspecies it is brown. The left ear is slightly above the eyes on the vertical plane, whereas the right ear is slightly below the eyes. The underparts vary from white to reddish buff among the subspecies and are either mostly unpatterned or bear a varying number of tiny blackish-brown speckles. The beak varies from pale horn to dark buff, corresponding to the general plumage hue, and the iris is blackish brown. The feet, like the beak, also vary in color, ranging from pink to dark pinkish-grey and the talons are black.


Barn owls occur in all of Europe (except Fennoscandia and Malta), most of Africa apart from the Sahara, the Indian subcontinent, Southeast Asia, Australia, many Pacific Islands, and North, Central, and South America. In general, they are considered to be sedentary, and indeed many individuals remain in chosen locations even when better foraging areas nearby become vacant. Barn owls are birds of open country such as farmland, plantation, shrubland, savanna, or grassland with some interspersed woodland. They prefer to hunt along the edges of woods or in rough grass strips adjoining pasture. For nesting and roosting, they choose holes in trees, fissures in cliffs, disused buildings, chimneys, hay sheds, barns, or silos.

8-5-2017 RONDA, ANDALUCIA - EUROPEAN GOLDFINCH (Carduelis carduelis)



The European goldfinch (Carduelis carduelis) is a small passerine bird that is native to Europe, North Africa and western and central Asia. It has been introduced to other areas, including Australia, New Zealand and Uruguay. The goldfinch is often depicted in Italian Renaissance paintings of the Madonna and Child.

Males and females of this species are very similar, with a red face, black and white head, warm brown upper parts, white underparts with buff flanks and breast patches, and black and yellow wings. Males can often be distinguished by a larger, darker red mask that extends just behind the eye. The shoulder feathers are black, whereas they are brown on the females. In females, the red face does not extend past the eye. The ivory-colored bill is long and pointed, and the tail is forked. Goldfinches in breeding condition have a white bill, with a greyish or blackish mark at the tip for the rest of the year. Juveniles have a plain head and a greyer back but are unmistakable due to the yellow wing stripe. Adults molt after the breeding season and at this time appear less colorful until the tips of the newly grown feathers wear away.

8-5-2017 SEVILLE, ANDALUCIA - ROSE RINGED PARAKEET (Psittacula krameri)


The Rose-ringed parakeet (Psittacula krameri) is one of the few parrot species that have successfully adapted to living in disturbed habitats. As a popular pet species, escaped birds have colonized a number of cities around the world, including Northern and Western Europe. These parakeets are also capable of living in a variety of climates outside their native range and are able to survive low winter temperatures in Northern Europe. The species is not threatened, but its popularity as a pet and unpopularity with farmers have reduced its numbers in some parts of its native range.

The Rose-ringed parakeet is a medium-sized parrot. The adult male sports a red and black neck ring, and the hen and immature birds of both sexes either show no neck rings or display shadow-like pale to dark grey neck rings. Both sexes have a distinctive green color in the wild, and captive-bred ringnecks have multiple color mutations including blue, violet, and yellow.



Rose-ringed parakeets are native to Africa and South Asia. They don't migrate and live in a wide variety of habitats. They can be found in grasslands, savanna, shrubland, rainforests, mangroves, and wetlands. These birds also occur in rural gardens and agricultural areas.


Rose-ringed parakeets are social birds. They are active during the day spending their time, foraging, flying about, and resting in the shades of tree canopy during midday hours. They often gather in flocks that fly several miles to forage in farmlands and orchards. Rose-ringed parakeets are very noisy and have an unmistakable squawking call.

Rose-ringed parakeets are herbivores and usually feed on buds, fruits, vegetables, nuts, berries, and seeds. In India, they eat cereal grains, and during winter also pigeon peas. In Egypt during the spring, they feed on mulberry, and in summer they feed on dates and eat from sunflower and corn fields.


Rose-ringed parakeets are serially monogamous; they do not have life mates and often breed with another partner during the following breeding season. In northwest India, Rose-ringed parakeets form pairs from September to December. During this cold season, they select and defend nest sites, thus avoiding competition for sites with other birds. The female lays 1 to 7 eggs and incubates them alone for about 3 weeks. The chick hatch altricial meaning they are helpless and depend on their parents for feeding and protection. The young fledge at 7 weeks of age and become independent when they are 2 years old. Reproductive maturity is usually reached at the age of 3 years.


The population of the Rose-ringed parakeet appears to be increasing, but its popularity as a pet and unpopularity with farmers have reduced its numbers in some parts of its native range.

According to IUCN, the Rose-ringed parakeet is common and widespread throughout its range but no overall population estimate is available. However, there are estimates of its populations in Japan which includes around 100-10,000 introduced breeding pairs. Currently, the Rose-ringed parakeet is classified as Least Concern (LC) on the IUCN Red List, and its numbers today are increasing.

19-3-2017 BUTTERFLY WORLD, FLORIDA - BENGALESE FINCH (Lonchura striata var. domestica)


Known as the Society finch in North America and the Bengali finch or Bengalese finch elsewhere, Lonchura striata domestica is a domesticated finch not found in nature. It became a popular cage and trade bird after appearing in European zoos in the 1860s where it was imported from Japan. There have been many theories of the origin of domestication for the Bengalese finch, and we now know it took place primarily in Japan. Coloration and behavior were modified through centuries of selection in Asia, then later in Europe and North America. Another aspect of the Bengalese finch that evolved throughout the centuries is song production. Extensive research has been done and continues to be done on the different ways Bengalese finch songs are produced, how they are processed in the brain, what characteristics of the songs are preferred by females, and how their songs compare to the also commonly studied zebra finch.

They are generally given a diet of seeds, such as millets and canary seed, and greens. They will not usually take live-foods, but it has been found they will often accept housefly pupae, which they crack like seeds. This is particularly useful if they are being used to foster species that require a high protein component to be successfully reared.

Bengalese finches are well adapted to captivity and the company of humans. They breed well and are good foster parents for other finch-like birds.

19-3-2017 BUTTERFLY WORLD, FLORIDA - BENGALESE FINCH (Lonchura striata var. domestica)


Known as the Society finch in North America and the Bengali finch or Bengalese finch elsewhere, Lonchura striata domestica is a domesticated finch not found in nature. It became a popular cage and trade bird after appearing in European zoos in the 1860s where it was imported from Japan. There have been many theories of the origin of domestication for the Bengalese finch, and we now know it took place primarily in Japan. Coloration and behavior were modified through centuries of selection in Asia, then later in Europe and North America. Another aspect of the Bengalese finch that evolved throughout the centuries is song production. Extensive research has been done and continues to be done on the different ways Bengalese finch songs are produced, how they are processed in the brain, what characteristics of the songs are preferred by females, and how their songs compare to the also commonly studied zebra finch.

They are generally given a diet of seeds, such as millets and canary seed, and greens. They will not usually take live-foods, but it has been found they will often accept housefly pupae, which they crack like seeds. This is particularly useful if they are being used to foster species that require a high protein component to be successfully reared.

Bengalese finches are well adapted to captivity and the company of humans. They breed well and are good foster parents for other finch-like birds.


While two males may not get along without other company, it has been found the best "pairing" for fostering is to use two males, this works better than either two females or a male and female pairing. Two males will usually accept eggs or even partly grown young without any hesitation.

These birds like to be close together and tend to all roost in one nest if kept in a group. In an aviary they lay eggs and crowd into a single nest, interfering with incubation (which is performed by the female and lasts 16 days) or damaging the eggs. Thus they breed better if kept as single pairs in individual breeding boxes. This sociability is also responsible for their American name of "society finch."

Bengalese finches are quite easy to look after. They are also quite easy to breed provided they are properly sexed. Obtaining a female-male pair can present a difficulty because both sexes look similar. However, it is possible to determine gender by behavior since males tend to display to females. One method to sex Bengalese is to place a single bird in a small cage completely isolated it from its own kind (both sight and hearing) and after several hours then introduce another Bengalese to the cage. If the first bird is a male, it will immediately display to the newcomer. Unfortunately, this does not necessarily mean the introduced bird is a female. But if the first bird does not display it is almost certainly a hen. Also, Society Finches can be housed with other finches including other societies, Zebra Finches, Gouldian Finches, and Spice Finches.

19-3-2017 MIAMI, FLORIDA - EASTERN GIANT SWALLOWTAIL BUTTERFLY (Papilio cresphontes)


The eastern giant swallowtail (Papilio cresphontes) is the largest butterfly in North America. It is abundant through many parts of eastern North America; populations from western North America and down into Panama are now (as of 2014) considered to belong to a different species, Papilio rumiko. Though it is often valued in gardens for its striking appearance, its larval stage can be a serious pest to citrus farms, which has earned its caterpillars the names orange dog or orange puppy. The eastern giant swallowtail caterpillars possess remarkable camouflage from predators by closely resembling bird droppings. They use this, along with their osmeteria, to defend against predators such as wasps, flies, and vertebrates.


The eastern giant swallowtail is common across the United States, reaching as far north as southern New England and southern Canada. South of the United States, it is found in parts of Mexico and also found in Jamaica and Cuba. The species was historically considered to occur in the western United States and into South America, but now those populations are treated as a separate species, the western giant swallowtail (Papilio rumiko), based largely on DNA evidence.

In the United States, P. cresphontes mostly inhabit deciduous forest and citrus orchards. They are only capable of overwintering in Florida and the deep South.

One of the eastern giant swallowtail's most notable features is its size. Females have an average wingspan of 5.5 in (14 cm), and up to 6.9 in (18 cm), while males' average is 5.8 in (15 cm), and up to 7.4 in (19 cm).


The wings are black with a horizontal yellow line across the forewings, and a diagonal yellow line across the hindwing. The underside of the wings is yellow with accents of black. A small patch of red on the ventral wing (within the small blue band) allows for distinction from the similar-looking Schaus' swallowtail. Seitz -"P. cresphontes Cr. (7a). Usually considered a slightly different variety of P. thoas. No cell-spot on the forewing; the fifth discal spot projecting further than the sixth. Claspers of the male separate above, the anal hook quite short, the lower part of the anal segment likewise quite different from that of P. thoas; harpe broad, rounded. A common species in eastern North America, occurring as far as Costa Rica in the south and southern Canada in the north; but the insect is a wanderer, which is found only now and then in the northern districts. In the United States it does not extend westward beyond the Mississippi plain, except in the Southern States. Its true home is the region adjoining the Gulf of Mexico. It occurs also on Cuba.

19-3-2017 MIAMI, FLORIDA - LONG TAILED FINCH (Poephila acuticauda)


The long-tailed finch (Poephila acuticauda) is a common species of estrildid finch found in northern Australia, from the Kimberley region to the Gulf of Carpentaria. It is a predominantly fawn-coloured bird with a pale grey head and prominent black bib and eyes. It inhabits dry savannah habitats in Australia and adapts readily to aviculture.


Common names for the species have been assigned or arisen from usage in aviculture, these include the long-tailed finch or longtail, blackheart finch, shaft-tail finch, orange-billed finch or grassfinch. Heck's grassfinch or finch, or Heck's longtail is applied to the eastern subspecies Poephila acuticauda hecki with red beaks, and the nominate subspecies with orange or yellow beaks is referred by the common name for the species.


The adult long-tailed finch is around 160 mm in length, the weight range of males is 13.5–16.2 grams and females 11.4–17.6 g. It has a prominent roundish black bib on its throat and upper chest and a long pointed black tail. It has pinkish brown upperparts with paler plumage below its bib over the lower breast and abdomen. It has a grey head, a white ear-patch, and black lores. It has black patches on its upper flanks and its rump and undertail coverts are white. The beak colour of the adult long-tailed finch varies from red through orange to yellow. Males and females are similar, except the females may be slightly duller and may have a slightly smaller bib. Females have shorter wings and tails than males on average, but their measurements, as well as throat bib size, generally lie within the range of male measurements. Furthermore, male and female plumage is indistinguishable in ultraviolet and visible light. A study published in 1999 showed that male long-tailed finches were unable to determine the sex of unfamiliar members of their species unless the latter bird declared its sex by song. Juveniles have black beaks and shorter tail feathers.

The subspecies are distinguished by the bill coloration, the nominate western group presenting a yellow colour and the eastern P. acuticauda hecki is red.


The species maintain a simple pair bond, with some records of extended family groups or in small flocks; the pairs remain in close proximity when engaged in their activities. Individuals use song to identify themselves to a partner, and they maintain contact with a 'distance call' Male P. acuticauda approach unfamiliar members of the species and engage in a courtship display, holding themselves in an upright posture and singing, before attempting to mate with the newcomer. Male newcomers will sometimes not declare their sex when confronted by a group of birds. The authors of the study propose this is a survival mechanism to reduce harassment, increase chances of acceptance into the group and hence chances of future reproduction.

The species breeds in natural hollows of trees or lower vegetation like tussocks of grass or shrubs. Where trees are available, the nest site may be over 4 metres from the ground, perhaps as high as 18 m. Eucalpyts are a favoured tree species, and pandanus are also selected. Breeding nests are carefully constructed from grass, the outer layer composed of broader blades 150–200 mm long and the inner chamber with a nesting cup woven from fine stems and seed-heads; woolly plant fibres and sometimes feathers are used to line the inner chamber. The total length of this structure is from 180 to 230 mm and is composed of up to 500 pieces, which includes an entrance is between 50 too 100 mm, in bottle or funnel shaped form. The nest used for roosting outside of the breeding season is a simpler design

Pairs share feeding responsibilities, and there has been one report of birds from older broods helping their parents raise the following brood, the first time that cooperative breeding has been recorded in an Australian estrildid finch. The clutch consists of four to six dull white oval eggs measuring 17 x 12 mm. A survey in the Kimberley recorded the clutch sizes as 10 × 4, 10 × 5 and 3 nests × 6 eggs. The incubation period is 13 to 17 days.


The long-tailed finch inhabits open woodland across northern Australia, from Derby in the northwest Kimberley region across to the east to the Leichhardt River in northwest Queensland.
It has an estimated global extent of occurrence of 1,000,000–10,000,000 km2. The IUCN has classified threats to the population of the species as being of least concern.


The long-tailed finch adapts readily to captivity, although it requires an aviary rather than a cage to thrive, and damp conditions need to be avoided. Export of the species has been banned from Australia, and they have become rather expensive in the UK. A caged pair are best kept on their own in the breeding season, because they become aggressive to other small finches. They breed readily in captivity, sometimes producing two broods a year, and live for around 5 to 8 years. In captivity, a pair of Heck's grass finches (P. a. hecki) might raise brood after brood continuously, which would jeopardise their health, if they are not fed with an adequate diet all year round. Alternatively, the sexes can be separated for the winter.

The species was well established in aviaries by the 1930s and regarded as robust specimens with interesting behaviours and an appealing appearance. The first record of successful breeding of the yellow-billed subspecies was in 1897, and the red-billed grass-finch was reproducing in English aviaries around a decade later, The species was also being bred in its native country during this period, including from pairs held at the Australian Museum. By the twenty first century these finches became popular amongst avicultural enthusiasts in European, Asian, and North American countries, and in South Africa, the species is recorded but rare in New Zealand. These finches are the second most common species in Britain, after the Gouldian finch Chloebia gouldiae.

19-3-2017 MIAMI, FLORIDA - ZEBRA LONGWING BUTTERFLY (Heliconius charithonia)



Although H. charithonia is to some extent static, maintaining a home range, adults do move between territories. Butterflies with Mexican origins migrate north into Texas, following the retracting temperature gradient. Rainfall has no effect on migration patterns. Arrival dates and duration of stay depend on the distance traveled: the longer the distance traveled, the shorter the duration of stay.
Roosting to deter predators
Adults roost in groups of up to 60 individuals on a nightly basis, returning to the same roost every night. These roosts provide protection to adults, the large groups deterring predators and retaining warmth. Solitary individuals, or very small roosts, avoid exhibiting proper warning signals so as not to attract predators. Pre-roosting interactions, which consist of sitting near one another, chasing each other briefly while fluttering, or basking, occur between butterflies from separate roosts, indicating that the butterflies are aware of other roosts in their home range. Despite this, the zebra longwing chooses to form smaller aggregations. The optimal roost size for predator deterrence is five individuals; roost size is also influenced by resource availability and foraging. H. charithonia roosts to display collective aposematism, deterring predators by conspicuously advertising their unpalatable taste.


H. charithonia adults form communal roosts nightly. Communal roosting occurs when individuals aggregate at a particular site for more than a few hours. Roosting begins as early as three hours before sunset and usually ends within two hours after sunrise. Since roosting is at night, adults need to be able to see at low light levels to locate roost sites, either when looking for twigs, tendrils, and dry leaves to land on to start a roost, or when searching for conspecifics that are already roosting. Their eyes also help them to recognize color patterns in conspecifics. UV rhodopsins in the eye help them to distinguish between 3-OHK yellow pigments, or ultraviolet colors, and other yellow pigments, which to the human eye is indistinguishable. At shorter distances, the butterflies recognize conspecifics via chemical cues. These chemical cues include volatile and nonvolatile substances. The significance of this chemical communication remains largely unknown for Heliconius in general. However, in H. melpomene, (E)-?-ocimene was found to attract males and females in diurnal situations.


At eclosion, the ratio is highly female biased, but the rest of the year the sex ratio is overall male biased (68% males). This is because males typically stay near their natal sites to find a mate, while females move around to find oviposition or feeding sites on Passiflora plants. Because females are very mobile, males rarely mate with relatives, and inbreeding rates are very low.

19-3-2017 MIAMI, FLORIDA - GOLD EDGED OWL BUTTERFLY (Caligo uranus)


An owl butterfly is (Caligo uranus) known for their huge eyespots, which resemble owls' eyes. They are found in the rainforests and secondary forests of Mexico, Central, and South America. Owl butterflies are very large, 65–200 mm (2.6–7.9 in), and fly only a few metres at a time.


An owl butterfly is a butterfly, in the genus Caligo, known for their huge eyespots, which resemble owls' eyes. They are found in the rainforests and secondary forests of Mexico, Central, and South America. Owl butterflies are very large, 65–200 mm (2.6–7.9 in), and fly only a few metres at a time, so avian predators, and we avid photographers! have little difficulty in following them to their settling place. However, the butterflies preferentially fly in dusk, when few avian predators are around.

They are usually large-sized and are characterized by large ocelli on the underside of their wings. These butterflies have the appearance of owls when landed and no doubt receive protection from predators with this camouflage. This rare giant owl butterfly is known as the Gold-edged is an owl butterfly belonging to the nymphalid family, Morphinae subfamily, tribe Brassolini.

19-3-2017 MIAMI, FLORIDA - PURPLE HONEYCREEPER (FEMALE) (Cyanerpes caeruleus)


The purple honeycreeper (Cyanerpes caeruleus ) is a small Neotropical bird in the tanager family Thraupidae. It is found in the tropical New World from Colombia and Venezuela south to Brazil, and on Trinidad. A few, possibly introduced birds have been recorded on Tobago.

The purple honeycreeper is 4.5 in (11.5 cm) long, weighs 0.42 oz (12 g) and has a long black decurved bill. The male is purple with black wings, tail and belly, and bright yellow legs. Females and immatures have green upperparts, and green-streaked yellowish-buff underparts. The throat is cinnamon, and there is a blue moustachial stripe. The call of purple honeycreeper is a thin high-pitched zree. The Trinidadian subspecies C. c. longirostris has a longer bill than the mainland forms.


The species is a bird of northern South America, and besides the Amazon Basin and the Guianas, a coastal range occurs west of the Andes, including parts of southern Panama. In the south, its range extends to the extreme western Pantanal. Though it is most frequently seen in the lowlands up to 3,300 ft (1,000 m) ASL or so, it has been encountered as high as 7,500 ft (2,300 m) ASL.

This is a forest canopy species, but also occurs in cocoa and citrus plantations. At the upper limit of its altitudinal range, it frequents premontane rainforest, usually rather low-growing (33–50 ft/10–15 m) and full of epiphytes and mosses, and even elfin forest and páramo.


The purple honeycreeper is often found in small groups. It feeds on nectar (particularly from bromeliad and similar flowers, to which its bill shape is adapted), berries and seeds (i.e., Trema and Clusia ), fruit (i.e., bananas and papayas) and insects, mainly in the canopy. It is a bold and inquisitive bird, responding readily to the call of the ferruginous pygmy owl (Glaucidium brasilianum ) by coming out of cover and searching for the presumed predator to mob it. The female purple honeycreeper builds a small cup nest in a tree, and incubates the clutch of two brown-blotched white eggs.
