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 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.

28-3-2017 TARCOLES RIVER COSTA RICA - ROSEATE SPOONBILL (Platalea ajaja)

The Roseate spoonbill (Platalea ajaja) is a gregarious wading bird of the ibis and spoonbill family, Threskiornithidae. It is a resident breeder in both South and North America. Plume hunting in the 18th and 19th centuries almost drove these beautiful birds to extinction.

Adult Roseate spoonbills have a bare greenish head and a white neck, back, and breast (with a tuft of pink feathers in the center when breeding), and are otherwise a deep pink. The colors can range from pale pink to bright magenta, depending on age, whether breeding or not, and location. Unlike herons, spoonbills fly with their necks outstretched, and they alternate groups of stiff, shallow wingbeats with glides.

Roseate spoonbills are resident breeders in South America mostly east of the Andes and in coastal regions of the Caribbean, Central America, Mexico, the Gulf Coast of the United States, and from central Florida's Atlantic coast at least as far north as South Carolina's Myrtle Beach. These birds inhabit coastal marshes, bays, lagoons, mangroves, and mudflats. They usually nest and roost in trees and shrubs near water.

Roseate spoonbills are gregarious birds and prefer to feed and fly in groups. They are active during the day spending many hours foraging in shallow fresh or coastal waters. The birds feed by swinging their bill from side to side as they steadily walk through the water, often in groups. Their spoon-shaped bill allows them to sift easily through mud feeling and looking for prey. The bill has sensitive nerve endings and once the birds feel the prey touch their bill they snap it closed. Roseate spoonbills roost in colonies often with other waders. They sleep standing, often on one leg with their head hidden under a shoulder. These birds are usually silent but when alarmed they will produce a low-pitched 'huh-huh-huh'; when feeding they may utter a very low, guttural sound.

Roseate spoonbills are serially monogamous and stay with one partner during one breeding season. They nest in small colonies and males constantly defend their territories against intruders. Preferred nesting areas usually include shrubs, trees, or often mangroves. The nest is a large cup-shaped structure made with small branches and stems. The female lays 2 to 5 whitish with brown markings eggs and both parents incubate them for 22-23 days. The chicks are altricial. They are born naked, helpless, and blind. At 35-42 days after hatching the young leave the nest and begin to fly when they are 7-8 weeks old.

14-4-2017 GIBRALTAR - YELLOW LEGGED GULL (Larus michahellis)

The Yellow-legged Gull (Larus michahellis) is a large, robust seabird with a commanding presence. Its size can be quite variable, with the smallest females being scarcely larger than a Common Gull, and the largest males approaching the heft of a Great Black-backed Gull. Adults typically exhibit a grey back, a shade lighter than that of the Lesser Black-backed Gull, and their heads are notably whiter in the autumn months. A distinctive feature is their yellow legs, which give this species its common name.

When observing the Yellow-legged Gull, look for the yellow legs that contrast with the grey back and the white head, which becomes even whiter during the autumn. The wing tips are black with limited white spots, and adults have a red spot on the bill. The eye is surrounded by a red ring. Juveniles can be identified by their paler head, rump, and underparts, dark bill and eyes, and a black band on the tail.

This gull favors a variety of coastal environments, often nesting on sea cliffs, islands, and occasionally on buildings within urban settings. It is also known to breed on trees in some regions.

The Yellow-legged Gull has a breeding range centered around the Mediterranean Sea, extending to the Atlantic islands and coasts as far north as Brittany and west to the Azores. Its presence is also noted on the western side of the Black Sea.

The species is known for its adaptability, with many individuals remaining in the same area year-round, while others migrate to milder regions of western Europe or head south to areas such as Senegal and the Red Sea. Post-breeding dispersal can lead to increased numbers in regions like southern England from July to October.

The vocalizations of the Yellow-legged Gull are characterized by a loud, laughing call that is deeper and more nasal than that of the Herring Gull.

Breeding typically occurs in colonies, with nests constructed on the ground or cliff ledges. The nests are mounds of vegetation, and the species is known for its vigorous defense of its eggs, usually numbering three. Incubation lasts for 27–31 days, and fledging occurs after 35–40 days.

An opportunistic forager, the Yellow-legged Gull is omnivorous, feeding on a wide range of items from rubbish tips to field prey, coastal offerings, and even other seabirds' catches. Remarkably, during periods of food scarcity, such as the lockdown in Italy in 2020, these gulls have been observed preying on larger animals like rats and rock doves.

1-4-2017 MIAMI, FLORIDA - BROWN PELICAN (MALE) (Pelecanus occidentalis)

The back, rump, and tail are streaked with gray and dark brown, sometimes with a rusty hue. The male and female are similar, but the female is slightly smaller. The nonbreeding adult has a white head and neck, and the pre-breeding adult has a creamy yellow head. The pink skin around the eyes becomes dull and gray in the non-breeding season. It lacks any red hue, and the pouch is strongly olivaceous ochre-tinged and the legs are olivaceous gray to blackish-gray. It has pale blue to yellowish-white irides which become brown during the breeding season. During courtship, the bill becomes pinkish red to pale orange, redder at the tip, and the pouch is blackish. Later in the breeding season, the bill becomes pale ash-gray over most of the upper jaw and the basal third of the mandible. The Brown pelican is exceptionally buoyant due to the internal air sacks beneath its skin and in its bones. It is as graceful in the air as it is clumsy on land.

The Brown pelican (Pelecanus occidentalis) has been described as a comically elegant bird. Groups of these seabirds glide above surf along western and southern coasts, gracefully echoing the waves with their rise and fall. They plunge-dive from high up to feed, the force of impact serving to stun small fish, which they then scoop up. Today this species is fairly common - a good example of recovery from the pesticide pollution that once threatened them with extinction.

The Brown pelican is the smallest of the eight extant pelican species but is often one of the larger seabirds in their range nonetheless. Like all pelicans, it has a very long bill, measuring 280 to 348 mm (11.0 to 13.7 in) in length. The nominate subspecies in its breeding plumage has a white head with a yellowish wash on the crown. The nape and neck are dark maroon–brown. The upper sides of the neck have white lines along the base of the gular pouch, and the lower foreneck has a pale yellowish patch. The feathers at the center of the nape are elongated, forming short, deep chestnut crest feathers. It has a silvery gray mantle, scapulars, and upperwing coverts (feathers on the upper side of the wings), with a brownish tinge. The lesser coverts have dark bases, which gives the leading edge of the wing a streaky appearance. 

The uppertail coverts (feathers above the tail) are silvery white at the center, forming pale streaks. The median (between the greater and the lesser coverts), primary (connected to the distal forelimb), secondary (connected to the ulna), and greater coverts (feathers of the outermost, largest, row of upperwing coverts) are blackish, with the primaries having white shafts and the secondaries having variable silver-gray fringes. The tertials (feathers arising in the brachial region) are silver-gray with a brownish tinge. The underwing has grayish-brown remiges with white shafts to the outer primary feathers. The axillaries and covert feathers are dark, with a broad, silver–gray central area. The tail is dark gray with a variable silvery cast. The lower mandible is blackish, with a greenish-black gular pouch at the bottom for draining water when it scoops out prey. The breast and belly are dark, and the legs and feet are black. It has a grayish-white bill tinged with brown and intermixed with pale carmine spots. The crest is short and pale reddish-brown in color. 

The Brown pelican occurs throughout the Pacific, Atlantic, and Gulf Coasts of the Americas. Most brown pelican populations are resident (nonmigratory) and dispersive (moving from their birth site to their breeding site, or their breeding site to another breeding site); however, some populations migrate, depending on local conditions. Brown pelicans are strictly marine and coastal birds but occasionally follow large rivers during storms. They avoid the open sea and rarely occur far offshore, usually frequenting shallow waters along coasts, as well as estuaries and bays. They breed on the arid coasts of flat, bare, remote islands, or occasionally in mangroves. Brown pelicans can often be seen around fishing ports.

Brown pelicans, after bathing, use their beaks to spread oil from the uropygial gland over their feathers.

Courtship displays by Brown pelicans usually last 2-4 days, but sometimes as long as three weeks.

Brown pelicans incubate their eggs by means of their webbed feet, turning the eggs from time to time.

Brown pelicans are the only type of pelican that dive in order to catch prey. They glide low above the water and when they see a fish they fly to a height of 10 m (30 ft), fold their wings back, and plunge down into the sea.

Brown pelicans do exercises, including stretching and turning their pouch inside out to maintain its flexibility.

Brown pelicans are very gregarious and live throughout the year in flocks. They are diurnal but sometimes forage at night during a full moon. They sleep on land either while standing on both their feet or resting on their breast and belly, their head sideways on their shoulder with their beak tilted towards the side. This is the only pelican species that dives from height as the main method of obtaining food. Their air sacs enable buoyancy for them in the water. They do not swim under the water but plunge their head below the surface when catching prey. Brown pelicans are territorial during the nesting period. Threat displays, often carried out when another pelican is too close to an individual’s nest involve head swaying, indicating readiness to interact, and bowing and a "hrraa-hrraa" sound. Young pelicans who approach a nest too closely are often killed.

Brown pelicans do not have many natural enemies. Although nests on the ground are sometimes destroyed by flooding, hurricane, or other natural disasters, people pose the biggest threat to pelicans. In the early 20th and late 19th centuries, pelicans’ feathers were sought after to adorn women’s clothing, especially hats. Today tourists and fishermen threaten them by disturbing their colonies, especially in Mexico.

1-4-2017 MIAMI, FLORIDA - BROWN PELICAN (FEMALE) (Pelecanus occidentalis)

The Brown Pelican (Pelecanus occidentalis) is a member of the pelican family, Pelecanidae. It is one of the smaller pelican species, yet remains a large seabird with a distinctive long bill and large throat pouch. The adult pelican is noted for its brown and gray plumage, with a white head and neck during the nonbreeding season and a yellowish wash on the crown during breeding. The nape and neck are dark maroon-brown, and the legs range from olivaceous gray to blackish-gray.

Adult Brown Pelicans are identified by their white and yellowish heads with a dark brown nape during breeding season, transitioning to a white head and neck in nonbreeding adults. Juveniles are overall grayish-brown with paler underparts. In flight, they are graceful with a steady wingbeat and can be seen gliding low over the water's surface.

This species is strictly marine, favoring shallow waters near coasts, estuaries, and beaches. It is also found in mangrove swamps and occasionally inland freshwater lakes.

The Brown Pelican is found along the Atlantic Coast from New Jersey to the Amazon River, and along the Pacific Coast from British Columbia to Peru, including the Galapagos Islands. It is a resident species with some populations showing migratory behavior, particularly in the northern parts of its range.

The Brown Pelican is a sociable bird, often seen in flocks. It has a unique feeding behavior among pelicans, diving from the air into the water to catch fish. It is also known for its buoyancy due to internal air sacks.

This species is relatively quiet, but during displays, it may produce a variety of grunts and low-pitched sounds.

Breeding occurs in colonies, often on secluded islands. Both sexes share in incubation duties, with a typical clutch consisting of two to three chalky white eggs. Chicks are initially pink, turning gray or black within a few weeks, and fledge after about 63 days.

The American White Pelican (Pelecanus erythrorhynchos) is similar but has white plumage and feeds from the water's surface rather than diving.

The Brown Pelican mainly feeds on fish, such as menhaden and anchovies, and occasionally consumes crustaceans, amphibians, and even the eggs and young of other birds. It dives from heights of up to 21 meters to capture prey.

The Brown Pelican is currently listed as Least Concern by the IUCN. Its populations have recovered significantly since the ban of DDT in the United States, where it was previously endangered due to pesticide exposure affecting breeding success.

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

The Great Horned Owl (Bubo virginianus), also known as the tiger owl or the hoot owl, is a formidable avian predator native to the Americas. This species is highly adaptable, with a vast range, and is recognized as the most widely distributed true owl in the Americas. Its plumage is generally mottled brown with barring, aiding in camouflage, and it possesses a distinctive white throat patch. The Great Horned Owl is one of the earliest nesting birds in North America.

This large owl has prominent ear tufts, known as plumicorns, which are thought to play a role in visual communication. Its eyes are among the largest of terrestrial vertebrates, and its face is framed by a facial disc, which can vary in color. The species exhibits sexual dimorphism, with females typically larger than males.

Great Horned Owls can be found in a variety of habitats, including deciduous, coniferous, and mixed forests, tropical rainforests, prairies, deserts, tundra, and even urban areas. They prefer areas where open habitats and woods are juxtaposed.

Their breeding habitat extends high into the subarctic of North America and down into South America to upland regions of Argentina, Bolivia, and Peru.

Great Horned Owls are primarily nocturnal, with activity peaking at night. They are known for their silent flight, facilitated by specialized feather structure. These owls are territorial and may use the same territory throughout their lives. They are also known for their aggressive defense of their nests.

The call of the Great Horned Owl is a series of deep hoots, often transcribed as "ho-ho-hoo hoo hoo." The female's call is higher in pitch. Vocalizations can vary from hoots to screeches and barks, especially when disturbed or during courtship.

Great Horned Owls are early breeders, with courtship beginning in late fall. They do not build their own nests but instead take over those made by other large birds. Clutch size ranges from 1 to 6 eggs, with incubation primarily by the female.

Their diet is diverse, primarily consisting of mammals and birds, including other raptors. They are capable hunters, taking prey ranging from small rodents to other birds of prey and even skunks.

1-4-2017 MIAMI, FLORIDA - GREAT CRESTED FLYCATCHER (Myiarchus crinitus)

The Great Crested Flycatcher, Myiarchus crinitus, is a robust bird of the tyrant flycatcher family. It is distinguished by its brownish upperparts and vibrant yellow underparts, complemented by a long, rusty brown tail and a pronounced bushy crest. This species exhibits no sexual dimorphism, meaning males and females are visually similar.

Adults typically range from 17 to 21 cm in length, with a wingspan of about 34 cm. They weigh between 27 and 40 grams. The throat and breast are a muted grey, contrasting with the more vivid colours of the body. Observers should look for the bird's characteristic crest and listen for its distinctive calls when identifying this species.

The Great Crested Flycatcher is most commonly found in deciduous forests and at the edges of clearings and mixed woodlands. It shows a preference for areas with an open canopy, such as second-growth forests or woodlands that have been selectively cut.

This bird is widespread across eastern and mid-western North America, with its breeding range extending from the southern parts of Canada down through the eastern United States. It winters in southern Mexico, the Yucatán Peninsula, and along the coasts of Central America. Some populations are resident year-round in southern peninsular Florida.

The Great Crested Flycatcher dwells mostly in the treetops and is rarely found on the ground. It employs a sit-and-wait hunting strategy from high perches, often accompanied by head bobbing. It may also hover or crash into foliage to catch prey.

The male's dawn song is a three-part whistle, starting with a "wheerreep," followed by a higher-pitched "whee," and ending with a soft low "churr." This song is typically heard just before dawn. The species also produces various calls, including a series of fast ascending "huit" sounds when stressed or excited, and a loud "whee-eep" for communication between mates or parents and offspring. Alarm or stress is indicated by a rapid succession of harsh rasps.

Great Crested Flycatchers are socially monogamous, with some pairs reforming in subsequent years. Nest building is primarily the female's responsibility, with the male guarding closely. They prefer large cavities for nesting, whether natural or excavated by other species, and will also use man-made structures. The nest is composed of vegetation, plant fibres, and sometimes artificial materials. They lay a single clutch of 4-8 eggs, incubated solely by the female. After hatching, both parents feed the insect-dominated diet to the nestlings.

Insects and other invertebrates constitute the majority of this bird's diet, although it will also consume small fruits and berries. It prefers butterflies, moths, beetles, grasshoppers, crickets, bees, and wasps over flies and spiders.

27-11-2015 SINGAPORE ZOO - GIANT PANDA (Ailuropoda melanoleuca)

The giant panda (Ailuropoda melanoleuca), sometimes called a panda bear or simply panda, is a bear species endemic to China. It is characterised by its bold black-and-white coat and rotund body. The name "giant panda" is sometimes used to distinguish it from the red panda, a neighboring musteloid. Though it belongs to the order Carnivora, the giant panda is a folivore, with bamboo shoots and leaves making up more than 99% of its diet. Giant pandas in the wild occasionally eat other grasses, wild tubers, or even meat in the form of birds, rodents, or carrion. In captivity, they may receive honey, eggs, fish, yams, shrub leaves, oranges, or bananas along with specially prepared food.

The giant panda lives in a few mountain ranges in central China, mainly in Sichuan, and also in neighbouring Shaanxi and Gansu. As a result of farming, deforestation, and other development, the giant panda has been driven out of the lowland areas where it once lived, and it is a conservation-reliant vulnerable species.

A 2007 report showed 239 pandas living in captivity inside China and another 27 outside the country. By December 2014, 49 giant pandas lived in captivity outside China, living in 18 zoos in 13 countries. Wild population estimates vary; one estimate shows that there are about 1,590 individuals living in the wild, while a 2006 study via DNA analysis estimated that this figure could be as high as 2,000 to 3,000. Some reports also show that the number of giant pandas in the wild is on the rise. By March 2015, the wild giant panda population had increased to 1,864 individuals. In 2016, it was reclassified on the IUCN Red List from "endangered" to "vulnerable", affirming decade-long efforts to save the panda. In July 2021, Chinese authorities also reclassified the giant panda as vulnerable.

The giant panda has often served as China's national symbol, appeared on Chinese Gold Panda coins since 1982 and as one of the five Fuwa mascots of the 2008 Summer Olympics held in Beijing.

1-4-2017 MIAMI, FLORIDA - AMERICAN WHITE IBIS (Eudocimus albus)

The American white ibis (Eudocimus albus) is a striking wader of the ibis family, Threskiornithidae. It is a medium-sized bird with a predominantly white plumage, which contrasts with its bright red-orange down-curved bill and long legs. The tips of its wings are black, a detail most apparent when the bird is in flight. Sexual dimorphism is present, with males being larger and possessing longer bills than females.

Adult American white ibises have distinctive pink facial skin and black wingtips visible in flight. In non-breeding condition, their bill and legs are a vivid red-orange. During breeding, the bill darkens at the tip and the legs take on a purple hue. Juveniles are brown and white, with the white becoming more prevalent as they mature. The species is relatively short-legged and bulky for its size, with a wingspan ranging from 90 to 105 cm.

The American white ibis frequents a variety of wetland habitats, including shallow coastal marshes, mangrove swamps, and inland wetlands such as marshes, ponds, and flooded fields. It adapts well to both natural and man-made water bodies.

This ibis is found from Virginia through the Gulf Coast of the United States, extending south through the coastal New World tropics. Its breeding range includes the Gulf and Atlantic Coasts, as well as the coasts of Mexico and Central America. The non-breeding range extends further inland and includes the Caribbean and parts of South America.

The American white ibis is a sociable bird, often seen in large flocks. It is territorial during the breeding season, with pairs forming monogamous bonds. Males may engage in extra-pair copulation to increase reproductive success. The species is known for its undulating flight pattern and honking calls.
