28-11-2016 JURONG, SINGAPORE - LACED WOODPECKER (MALE) (Picus vittatus)


The laced woodpecker (Picus vittatus) is a species of bird in the family Picidae.

It is found throughout Southeast Asia in the countries of Cambodia, China, Indonesia, Laos, Malaysia, Myanmar, Singapore, Thailand and Vietnam. A sole specimen recorded for Bangladesh has since been reidentified as a streak-breasted woodpecker.


Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical mangrove forest, and subtropical or tropical moist montane forest.

Typical green woodpecker, with a tea-green back, gray face, and solid black moustache stripe. Male has a bright red crown while female has a dull black one. Strikingly striped wings most readily seen in flight. Gives sharp, loud “kip” calls and more strident two-note calls during confrontations. In southwestern Thailand and southern Myanmar, look out for the similar Streak-breasted Woodpecker, which has a faded, indistinct moustache stripe in both sexes. Also compare with Streak-throated Woodpecker, which, as the name suggests, has noticeable streaking on the throat, as well as a more indistinct moustache stripe.

28-11-2016 JURONG, SINGAPORE - BLACK CROWNED NIGHT HERON (Nycticorax nycticorax)


The Black-crowned night heron (Nycticorax nycticorax) is a medium-sized heron found throughout a large part of the world. These birds have a stocky appearance as if hunched over, the head tucked down into the shoulders, and they are usually seen with this posture. They are most active at dusk or at night when their ghostly forms fly from their daytime roosts to the wetlands where they forage.


Adult birds have a black crown and back with the remainder of the body white or grey, red eyes, and short yellow legs. They have pale gray wings and white under parts. Two or three long white plumes, erected in greeting and courtship displays, extend from the back of the head. The sexes are similar in appearance although the males are slightly larger. Black-crowned night herons do not fit the typical body form of the heron family. They are relatively stocky with shorter bills, legs, and necks than their more familiar cousins, the egrets and "day" herons. Their resting posture is normally somewhat hunched but when hunting they extend their necks and look more like other wading birds. Immature birds have dull grey-brown plumage on their heads, wings, and backs, with numerous pale spots. Their underparts are paler and streaked with brown. The young birds have orange eyes and duller yellowish-green legs.

28-11-2016 JURONG, SINGAPORE - SADDLE BILLED STORK (Ephippiorhynchus senegalensis)


The saddle-billed stork or saddlebill (Ephippiorhynchus senegalensis ) is a large wading bird in the stork family, Ciconiidae. It is a widespread species which is a resident breeder in sub-Saharan Africa from Sudan, Ethiopia and Kenya south to South Africa, and in The Gambia, Senegal, Côte d'Ivoire and Chad in west Africa. It is considered endangered in South Africa.

It is a close relative of the widespread Asian and Australian black-necked stork, the only other member of the genus Ephippiorhynchus.


This is a huge bird that regularly attains a height of 145 to 150 cm (4 ft 9 in to 4 ft 11 in), a length of 142 cm (4 ft 8 in) and a 2.4 to 2.7 m (7 ft 10 in to 8 ft 10 in) wingspan. While heights published have been in the aforementioned narrow range, reportedly adult saddle-billed storks in captivity can attain a height of up to 150 to 180 cm (4 ft 11 in to 5 ft 11 in). The male of the species is larger and heavier than the female, with a range of 5.1–7.52 kg (11.2–16.6 lb), with a mean mass of 6.38 kg (14.1 lb). The female is usually between 5 and 6.84 kg (11.0 and 15.1 lb), with a mean mass of 5.95 kg (13.1 lb). Among the large storks, the saddle-billed broadly overlap in size with the two larger Leptoptilos and the Jabiru stork but possesses a longer, more slender neck and slightly longer legs than the other largest storks, so the saddle-billed is likely to be the tallest extant species of the family. Its extremely long legs measure up to 36.5 cm (14.4 in)) in tarsus length. The long bill measures from 27.3 to 36 cm (10.7 to 14.2 in). The sexes can be readily distinguished by the golden yellow irises of the female and the brown irises and dangling yellow wattles of the male. It is therefore one of the few storks to display sexual dimorphism in colour.

4-2-2018 MONTE CORONA, VALENCIA - EGYPTIAN BIRD GRASSHOPPER (Anacridium aegyptium)


Anacridium aegyptium, the Egyptian grasshopper or Egyptian locust, is a species of insect belonging to the subfamily Cyrtacanthacridinae.

Anacridium aegyptium var. rubrispinum Bei-Bienko, 1948 - Anacridium rubrispinum Bei-Bienko, 1948

A fairly common species, the Egyptian grasshopper is present in most of Europe, the Afrotropical realm, eastern Palearctic realm, the Near East, and North Africa, and has recently been observed in Cape Town, South Africa.

These grasshoppers inhabit trees and shrubs, scrub land, maquis, and orchards in warm and bright environments, at an elevation from sea level to 1,500 m.


Anacridium aegyptium is one of the largest European grasshoppers. Adult males grow up to 30–56 mm (1.2–2.2 in) long, while females reach 46–70 mm (1.8–2.8 in) in length. Their bodies are usually gray, brown, or olive-coloured, and their antennae are relatively short and robust. The tibiae of the hind legs are blue, while the femora are orange. The hind femora have characteristic dark marks. They are also easily identified by their characteristic eyes, which have vertical black and white stripes. Their pronota show a dorsal orange stripe and several small white spots. The wings are clear with dark marks.


This species is a folivore, essentially feeding on leaves of various plants. It is a solitary species, harmless to crops. Adults are mainly seen in August and September, but they are active throughout the year. After mating, these grasshoppers overwinter as adults. Spawning occurs in spring just under the soil surface and the nymphs appear in April. These grasshoppers undergo several molts. Nymphs differ from adults in appearance; their color varies from yellow to bright green and ocher and the wings are absent or small, as they are gradually developed after each molt.

23-3-2017 MEDELLIN, COLUMBIA - MILITARY MACAW (Ara militaris)


The military macaw (Ara militaris) is a medium-sized macaw that gets its name from its predominantly green plumage resembling a military parade uniform. It is native to forests of Mexico and South America and though considered vulnerable in the wild, it is still commonly found in the pet trade industry.

10-11-2015 VILLALONGA RESERVOIR, VALENCIA - GREEN SANDPIPER (Tringa ochropus)


1-6-2015 VAL D'EBO, VALENCIA - SPANISH GATEKEEPER BUTTERFLY (Pyronia bathseba)


Pyronia bathseba, the Spanish gatekeeper, is a butterfly of the family Nymphalidae. It is found on the Iberian Peninsula and in France, Morocco, and Algeria. A similar gatekeeper species is Pyronia tithonus, which is found in northern Europe.

The wingspan is 18–19 mm. The butterfly is on wing from May to July depending on the location.

The larvae feed on Poaceae species, mainly Brachypodium species.

1-6-2015 VAL D'EBO, VALENCIA - KNAPWEED FRITILLARY BUTTERFLY (MALE) (Melitaea phoebe ssp. occitanica)


Melitaea phoebe, the knapweed fritillary, is a butterfly of the family Nymphalidae. It is found in the Palearctic realm, except the northernmost locations. It used to include Melitaea telona, recently revalidated as a distinct cryptic species.

The wingspan is 34–50 mm. M. phoebe. The largest Melitaea of the Old World, at least certain of its forms. The forewing much more pointed than in the previous species; equally variable in colour as well as the distinctness of the markings. The black markings are usually united, in some cases even covering nearly the whole wings, but in other cases may be strongly reduced. It is characteristic for this species that the reddish yellow submarginal lunate spot situated between the two median veins reaches with its vertex considerably farther into the disc than the other yellow lunate spots. This is especially the case on the forewing, but also on the hindwing the submarginal lunule between the 1. and 2. median veins projects farther basad than the others of the same row. Wheeler (1903) gives a short description.


The butterfly flies from April to September depending on the location. The larvae feed on Plantago and Centaurea species (including Centaurea jacea).

28-11-2016 JURONG, SINGAPORE - WHITE THROATED TOUCAN (Ramphastos tucanus)


The white-throated toucan (Ramphastos tucanus) is a near-passerine bird in the family Ramphastidae found in South America throughout the Amazon Basin including the adjacent Tocantins and Araguaia River drainage. It prefers tropical humid forest, but also occurs in woodland and locally in riverine forest within cerrado.

The white-throated toucan was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae. He placed it with the other toucans in the genus Ramphastos and coined the binomial name Ramphastos tucanus. Linnaeus specified the "habitat" as South America. The type locality was restricted to Suriname by the American ornithologists Ludlow Griscom and James Greenway in 1937. The genus name is from Ancient Greek ῥαμφηστης/rhamphēstēs meaning "snouted" (from ῥαμφη/rhampē meaning "bill"). The specific epithet tucanus is from the Guarani language and may mean "bonenose".


Like other toucans, the white-throated toucan is brightly marked and has a huge bill. It has a total length of 50–61 cm (19.5–24 in). Body weight is somewhat variable, ranging in adult birds from 425 to 830 g (0.937 to 1.830 lb). The male averages slightly larger, at a mass of 642 g (1.415 lb), while the female averages 580 g (1.28 lb). However, the subspecies R. t. cuvieri is larger, with males averaging 702 g (1.548 lb) and females averaging 687 g (1.515 lb).[13] Among standard measurements, the wing chord is 20.4 to 26.5 cm (8.0 to 10.4 in), the bill is 12.2 to 22 cm (4.8 to 8.7 in), the tail is 13.3 to 16.8 cm (5.2 to 6.6 in), and the tarsus is 4.5 to 5.6 cm (1.8 to 2.2 in). The only species of toucan that surpasses the white-throated in size is the toco toucan, however the R. t. cuvieri subspecies of white-throated toucan appears to perhaps be even heavier than the Toco species.

It has black plumage with a white throat and breast bordered below with a narrow red line. The rump is bright yellow and the crissum (the area around the cloaca) is red. The bare skin around the eye is blue. The bill has a yellow tip, upper ridge and base of the upper mandible, and the base of the lower mandible is blue. The rest of the bill is mainly black in R. t. cuvieri and mainly reddish-brown in R. t. tucanus, with intergrades showing a mixed coloration. Males are larger and longer-billed than females, but otherwise the sexes are alike.

Juveniles are noticeably shorter-billed, more sooty-black, and have duller plumage.

The white-throated toucan of the race cuvieri is virtually identical to the related channel-billed toucan of the race culminatus, but the latter is smaller and has a proportionally shorter bill with a more strongly keeled culmen. The call is often the best distinction between the species. White-throated has a yelping eeoo, hue hue, whereas channel-billed has a croaking song.


Small flocks or more commonly pairs of birds move through the forest with a heavy, rather weak, undulating flight, rarely flying more than 100 m (330 ft) at a time. This species is primarily an arboreal fruit-eater, but will also take insects, lizards, eggs, and small birds.

The 2–4 white eggs are laid in an unlined cavity high in a decayed section of a living tree, or in an old woodpecker nest in a dead tree.

Both sexes incubate the eggs for at 14–15 days, and the toucan chicks remain in the nest after hatching. They are blind and naked at birth, with short bills, and have specialised pads on their heels to protect them from the rough floor of the nest. They are fed by both parents, and fledge after about 6 weeks. The parents continue feeding the juveniles for several weeks after they have left the nest.

3-2-2018 GANDIA, VALENCIA - WHITE WAGTAIL (Motacilla alba)


3-2-2018 RIO SERPIS GANDIA, VALENCIA - EURASIAN HOOPOE (Upupa epops)


The Eurasian hoopoe, with its scientific name Upupa epops, is a bird of unmistakable appearance. It boasts a warm cinnamon plumage, contrasted by striking black and white wings, and a prominent black-tipped, fan-like crest which it can raise and lower. Its tail features a broad white band across a black background. The hoopoe's long, narrow bill curves downwards, adept for probing the soil, and is black with a fawn base.

When identifying the Eurasian hoopoe, look for its unique silhouette, characterized by its long, tapering bill and erectile crest. In flight, its broad and rounded wings display a bold black and white pattern, and its undulating flight is reminiscent of a large butterfly. The hoopoe's size ranges from 25 to 32 cm in length, with a wingspan of 44 to 48 cm, and it weighs between 46 and 89 grams.


The hoopoe is adaptable, favoring habitats with bare or lightly vegetated ground for foraging and vertical surfaces with cavities for nesting. These can include heathlands, wooded steppes, savannas, grasslands, and forest glades.

This species is native to Europe, Asia, and the northern half of Africa. It is migratory in the northern parts of its range, with European and north Asian birds wintering in the tropics. African populations tend to be sedentary throughout the year.

Hoopoes are known for their sunbathing and dust-bathing behaviors, often spreading their wings and tail against the ground. They are solitary foragers, predominantly feeding on the ground with occasional aerial pursuits.


The hoopoe's call is a soft, melodic "oop-oop-oop," which may vary between two to four syllables. This call is the likely origin of both its English and scientific names.

Hoopoes are monogamous, with pair bonds lasting a single season. They nest in cavities, with the female solely responsible for incubation. Clutch sizes vary geographically, with larger clutches in higher latitudes. The eggs are initially milky blue, becoming discolored in the nest.

While the hoopoe's appearance is quite distinctive, its call can be confused with that of the Himalayan cuckoo in certain regions.


The hoopoe's diet consists mainly of insects, but it may also consume small reptiles, frogs, seeds, and berries. It uses its bill to probe the soil for larvae, pupae, and insects, which are then beaten against a surface to remove indigestible parts.

The Eurasian hoopoe is classified as "Least Concern" by the IUCN. However, there has been a noted decline in populations since 2008, attributed to habitat loss and over-hunting in certain areas. Conservation efforts are in place in regions where the species is threatened.

19-3-2017 MIAMI, FLORIDA - INDIGO BUNTING (FEMALE) (Passerina cyanea)


The indigo bunting, Passerina cyanea, is a small, seed-eating avian member of the cardinal family. This diminutive bird is known for its vibrant blue plumage in males during the breeding season and its migratory habits. Females and non-breeding males are predominantly brown, with the males exhibiting a hint of their summer blue.

Adult males in breeding plumage are a brilliant blue, with darker wings and tail. Females and juveniles are brown with faint streaking. The species exhibits sexual dimorphism, with males changing coloration seasonally. Look for a short, conical beak and a body length of 11.5–13 cm.

Indigo buntings favor brushy forest edges, open deciduous woods, and farmland. They thrive in areas with a mix of clearings and dense shrubbery, which provide both feeding grounds and nesting sites.

During the breeding season, these birds can be found from southern Canada to northern Florida and from eastern Texas to southern Nevada. Come winter, they migrate to regions from southern Florida to northern South America.


The indigo bunting is a solitary feeder during the breeding season but may join flocks in winter. Males are territorial and will sing from perches to defend their domain and attract mates. They are monogamous, though not strictly faithful, and may hybridize with the lazuli bunting where their ranges overlap.

Males sing a high-pitched, buzzed "sweet-sweet chew-chew sweet-sweet" to mark territory and attract females. Both sexes use a sharp "chip!" as an alarm call and a buzzed "zeeep" in flight.

Females build nests in dense shrubs or low trees, laying 1-4 eggs, which they incubate alone. The species raises one to two broods per year, with males feeding fledglings while females prepare for the next clutch.

The lazuli bunting is similar but has orange on the breast and white wing bars. Where their ranges meet, the two species may interbreed.

Indigo buntings forage for insects, seeds, and berries. Insects are a staple during the breeding season, while seeds predominate in the winter diet. Young are fed protein-rich insects to support their growth.

The indigo bunting is classified as Least Concern, with a stable population estimated at 28 million individuals. Its extensive range and adaptability to human-altered landscapes have helped maintain its numbers.

1-2-2018 OLIVA MARJAL, VALENCIA - COMMON CHIFFCHAFF (Phylloscopus collybita)




1-2-2018 OLIVA MARJAL, VALENCIA - EURASIAN BLACKBIRD (MALE) (Turdus merula)


The Common Blackbird, Turdus merula, is a true thrush and a familiar sight in gardens and woodlands. The male is distinguished by its all-black plumage, bright yellow eye-ring, and orange-yellow bill, which darkens slightly during winter. Females and juveniles are more demure in their attire, sporting mainly dark brown feathers.

Adult males are entirely black with the exception of the yellow eye-ring and bill. Females are sooty-brown with a duller bill, and juveniles resemble females but have pale spots on their upperparts. The very young may also exhibit a speckled breast.

The Common Blackbird thrives in a variety of habitats including woodlands with dense undergrowth, gardens, parks, and hedgerows. It shows a preference for deciduous trees and areas with thick vegetation.

This species is widespread across Europe, western Asia, and North Africa. It has also been introduced to Australia and New Zealand. Its range varies from resident populations in the milder regions to partially or fully migratory populations in areas with more severe winters.


The Common Blackbird is territorial, especially during breeding season, with males displaying distinctive threat behaviors to ward off rivals. Outside of breeding season, they can be more sociable, often forming small flocks. The species is known for its adaptability to urban environments, where it may overwinter more readily than in rural settings.

The male's song is a melodious and fluted warble, often heard from elevated perches during the breeding season. The Common Blackbird also has a repertoire of calls including a sharp "seee" when agitated and a "pook-pook-pook" to signal ground predators.

Monogamous by nature, the Common Blackbird builds a neat, cup-shaped nest, often in dense shrubbery. The female lays three to five bluish-green eggs adorned with reddish-brown blotches. Both parents are involved in feeding the altricial chicks until they fledge.

31-1-2018 TURIA GARDENS, VALENCIA - MONK PARAKEET (Myiopsitta monachus)


The monk parakeet (Myiopsitta monachus), also known as the monk parrot or Quaker parrot, is a species of true parrot in the family Psittacidae. It is a small, bright-green parrot with a greyish breast and greenish-yellow abdomen. Its average lifespan is 20–30 years. It originates from the temperate to subtropical areas of South America. Self-sustaining feral populations occur in many places, mainly in areas of similar climate in North America and Europe.

The nominate subspecies of this parakeet is 29 cm (11 in) long on average, with a 48-centimetre (19 in) wingspan, and weighs 100 g (3.5 oz). Females tend to be 10–20% smaller, but can only be reliably sexed by DNA or feather testing. It has bright-green upperparts. The forehead and breast are pale gray with darker scalloping and the rest of the underparts are very light-green to yellow. The remiges are dark blue, and the tail is long and tapering. The bill is orange. The call is a loud and throaty chape(-yee) or quak quaki quak-wi quarr, and screeches skveet.

Domestic breeds in colors other than the natural plumage have been produced. These include birds with white, blue, and yellow in place of green. As such coloration provides less camouflage, feral birds are usually of wild-type coloration.


The monk parakeet and the cliff parrot are the only two parrot species that build a stick nest, in a tree or on a man-made structure, rather than using a hole in a tree. The monk parrot is a gregarious species which often breeds colonially, building a single large nest with separate entrances for each pair. In the wild, the colonies can become quite large, with pairs occupying separate "apartments" in composite nests that can reach the size of a small automobile. These nests can attract many other tenants, including birds of prey such as the spot-winged falconet (Spiziapteryx circumcincta), ducks such as the yellow-billed teal (Anas flavirostris), and even mammals. Their five to 12 white eggs hatch in about 24 days.


Unusually for a parrot, monk parakeet pairs occasionally have helper individuals, often grown offspring, which assist with feeding the young. 

The lifespans of monk parakeets have been given as 20-30 years; the former might refer to typical lifespans in captivity and/or in the wild, while the latter is in the range of maximum lifespans recorded for parakeets.

Monk parakeets probably have individual voice prints that allow them to recognize each other, independently from the used call type.

In its native range, the monk parakeet is very common. In Argentina, Brazil, and Uruguay, monk parakeets are regarded as major agricultural pests (as noted by Charles Darwin, among others). Their population explosion in South American rural areas seems to be associated with the expansion of eucalyptus forestry for paper pulp production, which offers the bird the opportunity to build protected nests in artificial forests where ecological competition from other species is limited.

Self-sustaining feral populations have been recorded in several U.S. states and various regions of Europe (namely Spain, Portugal, Azores, Madeira, Balearic Islands, Gibraltar, France, Corsica, Malta, Cyprus, Sardinia, Italy, Greece, Romania, Channel Islands, Great Britain, Ireland, and Belgium), as well as in British Columbia, Canada, Brazil, Mexico, Chile, Germany,Puerto Rico, Easter Island, South Korea, Singapore, and Japan. As it is an open-woodlands species, it adapts readily to urban areas.

31-1-2018 TURIA GARDENS, VALENCIA - EUROPEAN ROBIN (Erithacus rubecula)


The European robin (Erithacus rubecula), known simply as the robin or robin redbreast in Great Britain and Ireland, is a small insectivorous passerine bird, a member of the chat subfamily of the Old World flycatcher family. It is a plucky little bird, with a length of about 12.5–14.0 cm and a weight of 16–22 g. Both sexes are similarly adorned with an orange breast and face, lined with grey, brown upper-parts, and a whitish belly.

Adult robins can be identified by their orange breast and face, bordered by a bluish-grey on the sides of the neck and chest. The upperparts are brownish, or olive-tinged in British birds, and the belly is whitish. The bill and eyes are black. Juvenile robins are distinguishable by their spotted brown and white plumage, with patches of orange gradually appearing as they mature.

The European robin is a bird of diverse habitats, found in woodlands, gardens, and parks across its range. It is particularly associated with areas where the soil is dug or disturbed, allowing it easy access to its invertebrate prey.


This bird has a wide distribution across Europe, extending east to Western Siberia and south to North Africa. It is sedentary in most of its range except the far north, where it is migratory.

The robin is diurnal and is known for its boldness in human presence, often seen investigating gardeners at work. It is territorial, with males known to fiercely defend their territory. The robin's diet is primarily composed of insects and worms, but it will also consume berries and fruit, especially in autumn and winter.

The robin's song is a delightful fluting warble, more plaintive during the winter months. Both sexes sing, with the male's song typically starting before dawn and ending after dusk. Urban robins may sing at night, possibly to avoid noise pollution during the day.


Robins are versatile in their choice of nesting sites, often opting for unusual locations such as nooks in machinery or even discarded clothing. They typically lay two or three clutches of eggs per season, with the eggs being cream, buff, or white and speckled with reddish-brown.

The European robin is unique among the Erithacus genus, with its closest relatives being the Japanese robin and the Ryukyu robin, which are now placed in a different genus.

Robins primarily feed on insects, spiders, and worms. During colder months, their diet is supplemented with berries and fruit. They are also known to visit bird tables for seed mixtures and suet.

The European robin is classified as Least Concern by the IUCN, with a stable and possibly increasing population. It does not face any significant threats that would warrant concern for its long-term survival.

31-1-2018 XERACO, VALENCIA - HOUSE SPARROW (MALE) (Passer domesticus)


most parts of the world. The extent of its range makes it the most widely distributed wild bird on the planet. Because of its numbers, ubiquity, and association with human settlements, the House sparrow is culturally prominent. It is extensively, and usually unsuccessfully, persecuted as an agricultural pest. It has also often been kept as a pet and was a food item. Though it is widespread and abundant, its numbers have declined in some areas.

The plumage of the House sparrow is mostly different shades of grey and brown. The sexes exhibit strong dimorphism: the female is mostly buffish above and below, while the male has boldly colored head markings, a reddish back, and grey underparts. The male has a dark grey crown from the top of its bill to its back, and chestnut brown flanking its crown on the sides of its head. It has black around its bill, on its throat, and on the spaces between its bill and eyes (lores). It has a small white stripe between the lores and crown and small white spots immediately behind the eyes (postoculars), with black patches below and above them. The underparts are pale grey or white, as are the cheeks, ear coverts, and stripes at the base of the head. The upper back and mantle are a warm brown, with broad black streaks, while the lower back, rump, and upper tail coverts are greyish brown.


The House sparrow (Passer domesticus) is a small passerine bird found in  The male is duller in fresh nonbreeding plumage, with whitish tips on many feathers. Wear and preening expose many of the bright brown and black markings, including most of the black throat and chest patch, called the "bib" or "badge". The male's bill is dark grey, but black in the breeding season. The female has no black markings or grey crowns. Its upperparts and head are brown with darker streaks around the mantle and a distinct pale supercilium. Its underparts are pale grey-brown. The female's bill is brownish-grey and becomes darker in breeding plumage approaching the black of the male's bill. Juveniles are similar to adult female, but deeper brown below and paler above, with paler and less defined supercilia. Juvenile males tend to have darker throats and white postoculars like adult males, while juvenile females tend to have white throats. The bills of young birds are light yellow to straw, paler than the female's bill.

28-3-2017 TARCOLES RIVER COSTA RICA - BARE THROATED TIGER HERON (Tigrisoma mexicanum)


The bare-throated tiger heron (Tigrisoma mexicanum) is a wading bird of the heron family, Ardeidae, found from Mexico to northwestern Colombia, with one recorded sighting from the United States in Hidalgo County, Texas. It is 80 cm (31 in) in length and weighs 1,200 g (42 oz).

This large species is found in more open habitats than other Tigrisoma herons, such as river and lake banks. It waits often motionless for suitable prey such as fish, frogs or crabs to come within reach of its long bill.

This is a solitary breeder, not normally found in heron colonies. The nest is a small flattish stick platform in a tree into which 2–3 green-tinged white eggs are laid.

The throat is bare and is greenish-yellow to orange in all plumages. The adult has black crown and light grey sides of the head, the sides of the neck and the upperparts otherwise blackish narrowly barred buff. The median stripe down the fore-neck is white-bordered with black; the remaining underparts are dull cinnamon brown. The juvenile is buff coarsely barred with black, more mottled and vermiculated on wings; the throat, median underparts, and belly are whitish.

The flight is heavy, and the call is a hoarse howk-howk-howk. Males also give a booming hrrrowwr! call, especially at sunset. During emission of the call, the beak opens wide and undulations can be seen along the course of the throat from mid-thorax caudally.

28-3-2017 TARCOLES RIVER COSTA RICA - YELLOW CROWNED NIGHT HERON (Nyctanassa violacea)


The Yellow-crowned Night Heron (Nyctanassa violacea) is a stocky wading bird, with a robust build and a notable large head in proportion to its body. It possesses a hefty bill, set deep under its eyes, and exhibits a wingspan of 101 to 112 cm. The species displays sexual dimorphism, with females slightly smaller than males.

Adults are characterized by a smooth grey-blue body with a black scaled pattern on the wings. Their long legs, which turn coral, pink, or red during courtship, are initially yellow. The head is strikingly black and glossy, with white cheeks and a pale yellow crown that extends from the bill, between the eyes, to the back of the head. This distinctive feature gives the bird its common name. In flight, the Yellow-crowned Night Heron can be distinguished by its long, slow wing beats and legs that extend straight below the tail.

This heron favors shallow waters such as marshes, wooded swamps, and lakeshores for inland populations, and thickets, mangroves, and cliff-bound coasts for coastal populations. It is also found in periodically flooded areas and tolerates a range of water types from fresh to brackish and saline.

29-3-2017 TARCOLES RIVER, COSTA RICA - TURQUOISE BROWED MOTMOT (Eumomota superciliosa)


The turquoise-browed motmot (Eumomota superciliosa ) also known as Torogoz, is a colourful, medium-sized bird of the motmot family, Momotidae. It inhabits Central America from south-east Mexico (mostly the Yucatán Peninsula), to Costa Rica, where it is common and not considered threatened. It lives in fairly open habitats such as forest edge, gallery forest and scrubland. It is more conspicuous than other motmots, often perching in the open on wires and fences. From these perches it scans for prey, such as insects and small reptiles. White eggs (3–6) are laid in a long tunnel nest in an earth bank or sometimes in a quarry or fresh-water well. Its name originates from the turquoise color of its brow. It is the national bird of both El Salvador and Nicaragua, where it is known as "Torogoz" and "Guardabarranco" respectively.

The bird is 34 cm (13 in) long and weighs 65 g (2.3 oz). It has a mostly grey-blue body with a rufous back and belly. There is a bright blue strip above the eye and a blue-bordered black patch on the throat. The flight feathers and upperside of the tail are blue. The tips of the tail feathers are shaped like rackets and the bare feather shafts are longer than in other motmots. Although it is often said that motmots pluck the barbs off their tail to create the racketed shape, this is not true; the barbs are weakly attached and fall off due to abrasion with substrates and with routine preening.

Unlike most bird species, where only males express elaborate traits, the turquoise-browed motmot expresses the extraordinary racketed tail in both sexes. Research indicates that the tail has evolved to function differently for the sexes. Males apparently use their tail as a sexual signal, as males with longer tails have greater pairing success and reproductive success. In addition to this function, the tail is used by both sexes in a wag-display, whereby the tail is moved back-and-forth in a pendulous fashion. The wag-display is performed in a context unrelated to mating: both sexes perform the wag-display in the presence of a predator, and the display is thought to confer naturally selected benefits by communicating to the predator that it has been seen and that pursuit will not result in capture. This form of interspecific communication is referred to as a pursuit-deterrent signal.

The call is nasal, croaking and far-carrying.

The turquoise-browed motmot is a well-known bird in its range. It has acquired a number of local names including guardabarranco ("ravine-guard") in Nicaragua, Torogoz in El Salvador (based on its call) and pájaro reloj ("clock bird") in the Yucatán, based on its habit of wagging its tail like a pendulum. In Costa Rica it is known as momoto cejiceleste or the far-less flattering pájaro bobo ("foolish bird"), owing to its tendency to allow humans to come very near it without flying away.
