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.

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.

19-3-2017 MIAMI, FLORIDA - PIANO KEY BUTTERFLY (Heliconius melpomene)

Heliconius melpomene, the postman butterfly, common postman or simply postman, is a brightly colored, geographically variable butterfly species found throughout Central and South America. It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. Its coloration coevolved with another member of the genus, H. erato as a warning to predators of its inedibility; this is an example of Müllerian mimicry. H. melpomene was one of the first butterfly species observed to forage for pollen, a behavior that is common in other insect groups but rare in butterflies. 

Because of the recent rapid evolutionary radiation of the genus Heliconius and overlapping of its habitat with other related species, H. melpomene has been the subject of extensive study on speciation and hybridization. These hybrids tend to have low fitness as they look different from the original species and no longer exhibit Müllerian mimicry.

Heliconius melpomene possesses ultraviolet vision which enhances its ability to distinguish subtle differences between markings on the wings of other butterflies. This allows the butterfly to avoid mating with other species that share the same geographic range.

19-3-2017 MIAMI, FLORIDA - RICE PAPER BUTTERFLY (Idea leuconoe)

Idea leuconoe, also known as the paper kite butterfly, rice paper butterfly, large tree nymph, is a butterfly known especially for its presence in butterfly houses and live butterfly expositions. It has a wingspan of 12 to 14 cm. The paper kite is of Southeast Asian origin, but can also be found in Southern Taiwan and the Ryukyu Islands.

Larvae feed on Parsonsia species, Tylophora hispida, Parsonsia helicandra, Parsonsia spiralis, and Cynanchum formosanum so both the butterfly and larvae are poisonous.

The paper kite butterfly's forewings and hindwings are translucent silvery white with black spots, similar to the Idea lynceus.

19-3-2017 MIAMI, FLORIDA - POSTMAN BUTTERFLY (Heliconius melpomene)

Heliconius melpomene, the postman butterfly, common postman or simply postman, is a brightly colored butterfly found throughout Central and South America. It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. Its coloration coevolved with a sister species H. erato as a warning to predators of its inedibility; this is an example of Müllerian mimicry. H. melpomene was one of the first butterfly species observed to forage for pollen, a behavior that is common in other groups but rare in butterflies. 

Because of the recent rapid evolutionary radiation of the genus Heliconius and overlapping of its habitat with other related species, H. melpomene has been the subject of extensive study on speciation and hybridization. These hybrids tend to have low fitness as they look different from the original species and no longer exhibit Müllerian mimicry.

Heliconius melpomene possesses ultraviolet vision which enhances its ability to distinguish subtle differences between markings on the wings of other butterflies. This allows the butterfly to avoid mating with other species that share the same geographic range.

19-3-2017 MIAMI, FLORIDA - NORTHERN MOCKINGBIRD (Mimus polyglottos)

The Northern mockingbird (Mimus polyglottos) is a mockingbird commonly found in North America and has rarely been observed in Europe. The bird is known for its mimicking ability, as reflected by the meaning of its scientific name, "many-tongued thrush". The Northern mockingbird is also known for its intelligence and is the state bird of five states, appears in book titles, songs, and lullabies, and makes other appearances in popular culture.

The Northern mockingbird is a medium-sized bird with long legs and a tail. Males and females look alike. Its upper parts are colored gray, while its underparts have a white or whitish-gray color. It has parallel wing bars on half of the wings connected near the white patch giving it a distinctive appearance in flight. The black central rectrices and typical white lateral rectrices are also noticeable in flight. The iris is usually a light green-yellow or yellow, but there have been instances of an orange color. The bill is black with a brownish-black appearance at the base. The juvenile appearance is marked by the streaks on its back, distinguished spots and streaks on its chest, and a gray or grayish-green iris.

Northern mockingbirds breed in southeastern Canada, the United States, northern Mexico, the Bahamas, the Cayman Islands, and the Greater Antilles. These birds are generally year-round residents of their range, but the populations that live in the northern portion of their range move further south during the winter season. Northern mockingbirds prefer forest edges and open areas with sparse vegetation. In the eastern regions, suburban and urban areas such as parks and gardens are frequent residential areas. In western regions, desert scrub and chaparral are among their preferred habitats. When foraging for food, Northern mockingbirds prefer short grass.

Northern mockingbirds are omnivores. They eat insects, earthworms, berries, fruits, seeds, and occasionally lizards. They can drink from puddles, river and lake edges, or dew and rain droplets that amass onto plants. Adult mockingbirds may also drink sap from the cuts on recently pruned trees.

Northern mockingbirds are active during the day and are usually seen singly or in pairs. They forage on the ground or in vegetation and also fly down from a perch to capture their food. While foraging, mockingbirds frequently spread their wings in a peculiar two-step motion to display the white patches. When on the ground they move by hopping, walking, and may even running. Northern mockingbirds are aggressive and territorial birds, especially around prime feeding areas. They use various threat postures to fend off intruders and may even mob and dive at humans if they venture too close to nesting areas. Northern mockingbirds generally communicate with the help of songs and various calls. Both males and females sing, with the latter being generally quieter and less vocal. Males start singing in late January to February and continue into the summer and the establishing of territory into the fall. Females sing less often in the summer and fall and only sing when the male is away from the territory. Northern mockingbirds have four main calls; these include the nest relief call, hew call, chat or chatburst, and the begging call. The hew call is mainly used by both sexes for potential nest predators, conspecific chasing, and various interactions between mates. The differences between chats and chatbursts are frequency of use, as chats are year-round, and chatbursts occur in the fall. Another difference is that chatbursts appear to be used in territorial defense in the fall, and the chats are used when mockingbirds are disturbed. The nest relief and begging calls are only used by the males.

Northern mockingbirds form monogamous pairs that remain together for many years, but incidents of polygyny (one male to several females) have also been reported. These birds breed in the spring and early summer and produce 2-4 broods a year. The males arrive before the beginning of the season to establish their territories. They use a series of courtship displays to attract females to their sites. The males run around the area either to showcase their territory to the females or to pursue the females. The males also engage in a flight to showcase their wings. They sing and call as they perform all of these displays. Both the male and female are involved in the nest building. The male does most of the work, while the female perches on the shrub or tree where the nest is being built to watch for predators. The outer part of the nest is composed of twigs, while the inner part is lined with grasses, dead leaves, moss, or artificial fibers. The female lays 3 to 5 light blue or greenish speckled with dots eggs and incubates them for nearly 2 weeks. The chicks are altricial, meaning that, when hatched, they are born relatively immobile and defenseless and therefore require nourishment for a certain duration from their parents. After about 10 to 15 days of life, the chicks become independent and reach reproductive maturity after one year of life.

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

The Purple Honeycreeper, Cyanerpes caeruleus, is a diminutive and vibrant member of the tanager family Thraupidae. This Neotropical avian jewel is adorned with a striking plumage; the male boasts a deep purple hue with contrasting black wings, tail, and underbelly, and sports vivid yellow legs. The female and immature birds present a more subdued palette, with green upperparts and yellowish-buff underparts streaked with green. A cinnamon throat and a distinctive blue moustachial stripe complete their attire. Both sexes have a long, black, decurved bill, with the Trinidadian subspecies C. c. longirostris exhibiting a notably longer bill than its mainland counterparts.

When identifying the Purple Honeycreeper, look for the male's unmistakable purple and black coloration and the female's green and buff streaked appearance. The long, curved bill is a key feature for nectar feeding, and the bright yellow legs of the male are quite distinctive. Juveniles resemble females but may lack the blue moustachial stripe.

This species is primarily a denizen of the forest canopy, but it also adapts to human-altered landscapes such as cocoa and citrus plantations. It thrives in a variety of forest types, including low-growing premontane rainforests rich in epiphytes and mosses, as well as elfin forests and páramo at higher elevations.

The Purple Honeycreeper is found across northern South America, from Colombia and Venezuela through the Amazon Basin and the Guianas. Its range extends west of the Andes to parts of southern Panama and reaches the western fringes of the Pantanal. It is generally seen at elevations up to 1,000 meters above sea level but has been recorded as high as 2,300 meters.

This species is often observed in small groups, actively foraging in the canopy. It is known for its boldness and curiosity, especially in response to the calls of predators such as the ferruginous pygmy owl, which it will approach to mob. The Purple Honeycreeper's diet consists of nectar, berries, seeds, fruits like bananas and papayas, and insects.

The vocalization of the Purple Honeycreeper is a high-pitched, thin 'zree', which is characteristic of the species.

The female takes on the responsibility of constructing a small cup nest within a tree. She incubates a clutch of two eggs, which are white with brown blotches, nurturing the next generation of these forest gems.

The Purple Honeycreeper's diet is varied, including nectar from bromeliads and other flowers suited to its bill shape, as well as berries, seeds from plants like Trema and Clusia, and a range of fruits. It also consumes insects, foraging primarily in the forest canopy.

The IUCN Red List currently classifies the Purple Honeycreeper as Least Concern, indicating that, for now, this species does not face immediate threats to its survival.

19-3-2017 MIAMI, FLORIDA - RED LEGGED HONEYCREEPER (Cyanerpes cyaneus)

The red-legged honeycreeper (Cyanerpes cyaneus ) is a small songbird species in the tanager family (Thraupidae). It is found in the tropical New World from southern Mexico south to Peru, Bolivia and central Brazil, Trinidad and Tobago, and on Cuba, where possibly introduced. It is also rarely found in southern Texas.

The red-legged honeycreeper is on average 12.2 cm (4.8 in) long, weighs 14 g (0.49 oz) and has a medium-long black, slightly decurved, bill. The male is violet-blue with black wings, tail and back, and bright red legs. The crown of its head is turquoise, and the underwing, visible only in flight, is lemon yellow. After the breeding season, the male moults into an eclipse plumage, mainly greenish with black wings.

Females and immatures are mainly green, with paler, faintly streaked underparts. The legs are red-brown in the female, and brown in young birds.

The call of red-legged honeycreeper is a thin, high-pitched tsip.

This is a species of forest edge, open woodland, and cocoa and citrus plantations. The red-legged honeycreeper is often found in small groups. It feeds on insects and some fruit and nectar. It responds readily to the (easily imitated) call of the ferruginous pygmy owl (Glaucidium brasilianum ).

In Costa Rica red-legged honeycreepers generally breed between April and June. The nest is built entirely by the female and is placed in a shrub or tree several meters above the ground. The cup-shaped nest has thin side walls and is formed of stiff fibres. It is attached to the supporting twigs with cobwebs. The clutch consists of two eggs that are laid in early morning on consecutive days. They are 13.4 mm × 19.1 mm (0.53 in × 0.75 in) in size and have a white background with brown speckles forming a ring around the larger end. 

The female incubates the eggs for 12 or 13 days. When they first hatch the nestlings have their eyes closed and are covered with tuffs of grey down. They are brooded by the female but fed by both parents. They fledge after around 14 days.

A specimen studied in the Parque Nacional de La Macarena of Colombia was found to be free of blood parasites.

Common and widespread, the red-legged honeycreeper is not considered a threatened species by the IUCN.

19-3-2017 MIAMI, FLORIDA - EUROPEAN STARLING (FEMALE) (Sturnus vulgaris)

The Common Starling, Sturnus vulgaris, is a medium-sized passerine bird characterized by its glossy black plumage with a metallic sheen. Throughout the year, the plumage is speckled with white, though less so during the breeding season. Adults measure approximately 20 cm in length, with pink legs and a seasonally changing bill color—black in winter and yellow in summer. Juveniles display browner plumage compared to adults.

To identify the Common Starling, look for its iridescent black feathers, which may appear purple or green when reflecting light. The bird's bill is black in the winter and transitions to yellow in the summer, aiding in identification. The starling's flight is strong and direct, with pointed wings that are distinctive in the air. On the ground, its waddling gait is notable.

Common Starlings are highly adaptable, favoring urban and suburban areas where they find ample nesting and roosting opportunities. They also inhabit grasslands, such as farmlands and pastures, where short grass makes foraging for invertebrates easier.

Native to temperate Europe and western Asia, the Common Starling has been introduced to Australia, New Zealand, North America, and other regions. Its range extends from Europe to northern Africa and across the Palearctic to western Mongolia.

The Common Starling is a gregarious bird, especially in autumn and winter, forming large flocks known as murmurations. These flocks are thought to be a defense against predators. On the ground, starlings forage in groups, often following grazing animals to feed on disturbed invertebrates.

The Common Starling's song is a varied mix of melodic and mechanical sounds, including mimicked noises from other bird species and the environment. Males sing to attract mates and defend their territory. Calls include a harsh alarm scream and a variety of social chatters.

Breeding occurs in the spring and summer, with the female laying four to five glossy, pale blue eggs in a nest built within a natural or artificial cavity. Both parents share incubation duties, and the young fledge after about three weeks.

Omnivorous, the Common Starling's diet includes a wide range of invertebrates, seeds, and fruit. They employ various foraging techniques, such as probing the ground and catching flying insects.

Despite declines in some European populations, the Common Starling's global population is not considered to be declining significantly. It is classified as Least Concern by the International Union for Conservation of Nature (IUCN).

19-3-2017 MIAMI, FLORIDA - EASTERN GRAY SQUIRREL (Sciurus carolinensis)

The Eastern gray squirrel (Sciurus carolinensis) is a tree squirrel native to eastern North America; there it is the most prodigious and ecologically essential natural forest regenerator. Widely introduced to certain places around the world, the Eastern gray squirrel in Europe, in particular, is regarded as an invasive species.

The Eastern gray squirrel is a squirrel of medium size, and both males and females are of the same size and color. Its fur is mainly black or gray, the gray color being grizzled and often banded with gray and black guard hairs, tinged white, with the underside being white. Its tail is quite bushy and sometimes reddish in color and is used for maintaining balance while it leaps between branches. The overall fur color may change with different seasons, with the grayish fur being tawnier during summer, and the tail whiter.

Eastern gray squirrels are native to the eastern and mid-western parts of America, and to the south of the eastern parts of Canada. They range from Manitoba to New Brunswick, and south to Florida and East Texas. They inhabit large areas of mature, dense woodland ecosystems. These forests usually contain large mast-producing trees such as oaks and hickories, providing ample food sources. Close to human settlements, Eastern gray squirrels are found in parks and backyards of houses within urban environments and in the farmlands of rural environments.

Eastern gray squirrels are aggressive, alert, and inquisitive rodents, very fast when moving and jumping amongst the treetops. These squirrels are scatter-hoarder; they hoard huge quantities of food for the future and can make several thousand caches per season. They are more active in the daytime than at night, particularly at dawn and during the afternoon. Males and females may share the same nest during the breeding season, which they build in the forks of trees, and during cold winters, squirrels may also share these dreys to stay warm. The dens are usually lined with moss plants, thistledown, dried grass, and feathers. Females nest alone during pregnancy, and lactating females are particularly aggressive and left alone by other squirrels. These squirrels do not hibernate. To communicate with each other they use both vocalizations and posturing. They have a quite varied repertoire of vocalizations, including a squeak similar to that of a mouse, a low-pitched noise, a chatter, and a raspy "mehr mehr mehr". Other methods of communication include tail-flicking and other gestures, including facial expressions. Squirrels also make an affectionate coo-purring sound that biologists call the "muk-muk" sound. This is used as a contact sound between a mother and her kits and in adulthood, by the male when he courts the female during mating season.
