Booted Racket-tail (Ocreatus underwoodii)

by birdinfo • February 20, 2014 • 0 Comments

The Booted Racket-tail (Ocreatus underwoodii) is a species of hummingbird. It is found in the Andean cordillera of Bolivia, Colombia, Ecuador, Peru, and Venezuela. A population also occurs on the Venezuelan coast. This is the only species in the monotypic genus Ocreatus.

The upperparts are a golden green colour and the rump has a white bar. The throat and breast are a brilliant emerald green. The legs are feathered down to the feet with horny white short feathers. The tail is brownish black and deeply forked. The tail feathers on either side increase in length from the centre and the outermost ones are exceptionally long and have bare shafts tipped by oval plumes, which gives the species its common name.

Roseate Spoonbill (Platalea ajaja)

by birdinfo • February 20, 2014 • 0 Comments

The Roseate Spoonbill (Platalea ajaja) (sometimes placed in its own genus Ajaja) is a gregarious wading bird of the ibis and spoonbill family, Threskiornithidae. It is a resident breeder 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 on Central Florida’s Atlantic coast[4] Merritt Island National Wildlife Refuge adjoined with NASA Kennedy Space Center.

A 2010 study of mitochondrial DNA of the spoonbills by Chesser and colleagues found that the Roseate and Yellow-billed Spoonbills were each other’s closest relative, and the two were descended from an early offshoot from the ancestors of the other four spoonbill species. They felt the genetic evidence meant it was equally valid to consider all six to be classified within the genus Platalea or alternatively the two placed in the monotypic genera Platibis and Ajaja, respectively. However, as the six species were so similar morphologically, keeping them within the one genus made more sense.

The Roseate Spoonbill is 71–86 cm (28–34 in) long, with a 120–133 cm (47–52 in) wingspan and a body mass of 1.2–1.8 kg (2.6–4.0 lb). The tarsus measures 9.7–12.4 cm (3.8–4.9 in), the culmen measures 14.5–18 cm (5.7–7.1 in) and the wing measures 32.3–37.5 cm (12.7–14.8 in) and thus the legs, bill, neck and spatulate bill all appear elongated. Adults have a bare greenish head (“golden buff” when breeding) 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 bill is grey. There is no significant sexual dimorphism.

Like the American Flamingo, their pink color is diet-derived, consisting of the carotenoid pigment canthaxanthin. Another carotenoid, astaxanthin, can also be found deposited in flight and body feathers. The colors can range from pale pink to bright magenta, depending on age and location. Unlike herons, spoonbills fly with their necks outstretched. They alternate groups of stiff, shallow wingbeats with glides.

This species feeds in shallow fresh or coastal waters by swinging its bill from side to side as it steadily walks through the water, often in groups. The spoon-shaped bill allows it to sift easily through mud. It feeds on crustaceans, aquatic insects, frogs, newts and very small fish ignored by larger waders. In the United States a popular place to observe Roseate Spoonbills is “Ding” Darling National Wildlife Refuge in Florida. Roseate Spoonbills must compete for food with Snowy Egrets, Great Egrets, Tricolored Herons, and American White Pelicans.

The Roseate Spoonbill nests in shrubs or trees, often mangroves, laying 2 to 5 eggs, which are whitish with brown markings. Immature birds have white, feathered heads, and the pink of the plumage is paler. The bill is yellowish or pinkish.

Information about predation on adults is lacking. Nestlings are sometimes killed by turkey vultures, bald eagles, raccoons, and fire ants. In 2006, a 16-year-old banded bird was discovered, making it the oldest wild individual.

Ocellated Turkey (Meleagris ocellata)

by birdinfo • February 20, 2014 • 0 Comments

The Ocellated Turkey (Meleagris ocellata) is a species of turkey residing primarily in the Yucatán Peninsula. A relative of the Wild Turkey (Meleagris gallopavo), it was sometimes previously treated in a genus of its own (Agriocharis), but the differences between the two turkeys are currently considered too small to justify generic segregation. It is a relatively large bird, at around 70–122 cm (28–48 in) long and an average weight of 3 kg (6.6 lbs) in females and 5 kg (11 lbs) in males.

The Ocellated Turkey lives only in a 130,000 km2 (50,000 sq mi) range in the Yucatán Peninsula in Mexico—which includes all or part the states of Quintana Roo, Campeche, Yucatán, Tabasco, and Chiapas—as well as the northern parts of Belize and Guatemala.

The body feathers of both sexes are a mixture of bronze and green iridescent color. Although females can be duller with more green, the breast feathers do not generally differ and can not be used to determine sex. Neither sex possesses the beard typically found in Wild Turkeys. Tail feathers of both sexes are bluish-grey with an eye-shaped, blue-bronze spot near the end with a bright gold tip. The spots, or ocelli (located on the tail), for which the Ocellated Turkey is named, have been likened to the patterning typically found on peafowl. The upper, major secondary wing coverts are rich iridescent copper. The primary and secondary wing feathers have similar barring to that of North American turkeys, but the secondaries have more white, especially around the edges.

Both sexes have blue heads with some orange or red nodules, which are more pronounced on males. The males also have a fleshy blue crown covered with nodules, similar to those on the neck, behind the snood. During breeding season this crown swells up and becomes brighter and more pronounced in its yellow-orange color. The eye is surrounded by a ring of bright red skin, which is most visible on males during breeding season. The legs are deep red and are shorter and thinner than on North American turkeys. Males over one year old have spurs on the legs that average 4 cm (1.5 inches), which lengths of over 6 cm (2.5 inches) being recorded. These spurs are much longer and thinner than on North American turkeys.

Ocellated Turkeys are much smaller than any of the subspecies of North American Wild Turkey, with adult hens weighing about 4 kg (8 pounds) before laying eggs and 3 kg (6–7 pounds) the rest of the year, and adult males weighing about 5–6 kg (11–15 pounds) during breeding season.

Turkeys spend most of the time on the ground and often prefer to run to escape danger through the day rather than fly, though they can fly swiftly and powerfully for short distances as the majority of birds in this order do in necessity. Roosting is usually high in trees away from night hunting predators such as Jaguars and usually in a family group.

Female Ocellated Turkeys lay 8–15 eggs in a well concealed nest on the ground. She incubates the eggs for 28 days. The young are precocial and able to leave the nest after one night. They then follow their mother until they reach young adulthood when they begin to range though often re-grouping to roost.

The voice is similar to the northern species: the male making the “Gobbling” sound during the breeding season, while the female bird makes a “clucking” sound.

Branton and Berryhill (2007) have observed that the male Ocellated Turkey does not gobble per se like the Wild Turkey. Rather, his song is distinct and includes some six to seven bongo-like bass tones which quicken in both cadence and volume until a crescendo is reached whereupon the bird’s head is fully erect while he issues forth a rather high-pitched but melodious series of chops. The Ocellated Turkey will typically begin his singing 20 to 25 minutes before sunrise—similar to the Wild Turkeys in North America

Mute Swan (Cygnus olor)

by birdinfo • February 20, 2014 • 0 Comments

The Mute Swan (Cygnus olor) is a species of swan, and thus a member of the waterfowl family Anatidae. It is native to much of Europe and Asia, and (as a rare winter visitor) the far north of Africa. It is also an introduced species in North America,Australasia and southern Africa. The name ‘mute’ derives from it being less vocal than other swan species. Measuring 125 to 170 cm (49 to 67 in) in length, this large swan is wholly white in plumage with an orange bill bordered with black. It is recognisable by its pronounced knob atop the bill.

The Mute Swan was first formally described by the German naturalist Johann Friedrich Gmelin as Anas olor in 1789, and was transferred by Johann Matthäus Bechstein to the new genus Cygnus in 1803. It is the type species of the genus Cygnus.[5]Both cygnus and olor mean “swan” in Latin; cygnus is related to the Greek kyknos.[6][7]

Despite its Eurasian origin, its closest relatives are the Black Swan of Australia and the Black-necked Swan of South America, not the other Northern Hemisphere swans.[2] The species is monotypic with no living subspecies.

Mute Swan subfossils, 6,000 years old, have been found in post-glacial peat beds of East Anglia, Great Britain.[8] They have also been recorded from Ireland east to Portugal and Italy,[9] and from France, 13,000 BP (Desbrosse and Mourer-Chauvire 1972–1973).[full citation needed] The paleosubspecies Cygnus olor bergmanni, which differed only in size from the living bird, is known from fossils found in Azerbaijan.[citation needed]

Fossils of swan ancestors more distantly allied to the Mute Swan have been found in four U.S. states: California, Arizona, Idaho and Oregon.[10] The timeline runs from the Miocene to the late Pleistocene, or 10,000 BP. The latest find was in Anza Borrego Desert, a national park in California.[10] Fossils from the Pleistocene include Cygnus paloregonus from Fossil Lake, Oregon, Froman’s Ferry, Idaho, and Arizona, referred to by Howard in The Waterfowl of the World as “probably the mute type swan”.

Adults of this large swan typically range from 140 to 160 cm (55 to 63 in) long, although can range in extreme cases from 125 to 170 cm (49 to 67 in), with a 200 to 240 cm (79 to 94 in) wingspan.[4][12] Males are larger than females and have a larger knob on their bill. On average, this is the second largest waterfowl species after the Trumpeter Swan, although male Mute Swans can easily match or even exceed a male Trumpeter in mass.[4][13] Among standard measurements of the Mute Swan, the wing chord measures 53–62.3 cm (20.9–24.5 in), the tarsus is 10–11.8 cm (3.9–4.6 in) and the bill is 6.9–9 cm (2.7–3.5 in).

The Mute Swan is one of the heaviest flying birds, with males (known as cobs) averaging about 11–12 kg (24–26 lb) and the slightly smaller females (known as pens) weighing about 8.5–9 kg (19–20 lb).[4][14]While the top normal weight for a big cob is 15 kg (33 lb), one unusually big Polish cob weighed almost 23 kg (51 lb) and this counts as the largest verified weight for a flying bird, although it has been questioned whether this heavyweight could still take flight.

Young birds, called cygnets, are not the bright white of mature adults, and their bill is dull greyish-black, not orange, for the first year. The down may range from pure white to grey to buff, with grey/buff the most common. The white cygnets have a leucistic gene. All Mute Swans are white at maturity, though the feathers (particularly on the head and neck) are often stained orange-brown by iron and tannins in the water.[citation needed]

The morph immutabilis (“Polish Swan”) has pinkish (not dark grey) legs and dull white cygnets; as with white domestic geese, it is only found in populations with a history of domestication.

Long-tailed Broadbill (Psarisomus dalhousiae)

by birdinfo • February 19, 2014 • 0 Comments

The Long-tailed Broadbill (Psarisomus dalhousiae) is a species of broadbill that is found in the Himalayas, extending east through Northeastern India to Southeast Asia. It is the only bird in the genus Psarisomus. The Long-tailed Broadbill is about 25 cm (10 inches) in length and weighs between 50 and 60 grams. It can be identified by its shrill call.

The Long-tailed Broadbill is a forest bird that lives on insects. It is very sociable and normally travels in large, noisy parties except during the mating season. It builds a pear-shaped nest in a tree. The female usually lays between 5 and 6 eggs that are incubated by both sexes; both sexes also help to feed the young.

The scientific name commemorates Christina Broun, Countess of Dalhousie (1786–1839), wife of George Ramsay, 9th Earl of Dalhousie.

Malagasy Paradise Flycatcher (Terpsiphone mutata)

by birdinfo • February 19, 2014 • 0 Comments

The Malagasy Paradise Flycatcher (Terpsiphone mutata) is a species of bird in the Monarchidae family. It is found in Comoros, Madagascar, and Mayotte. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical moist lowland forests.

When Carl Linnaeus first described the Malagasy Paradise Flycatcher in 1766, he assigned it to the genus Muscicapa, which contained many of the Old World flycatchers. The species remained in that genus until 1827, when Constantin Wilhelm Lambert Gloger created the genus Terpsiphone for the paradise-flycatchers.[2] The genus name Terpsiphone comes from the Greek words terpsi, meaning “delighted in” (from terpo, “to delight”) and phone, meaning “voice”.[3] Thespecies name, mutata is Latin for “changed” or “different”.[4]

The Malagasy Paradise Flycatcher is thought to have evolved from African ancestors, as it appears to be more closely related to the African Paradise Flycatcher than the Asian Paradise Flycatcher.[5] There are six recognized subspecies, which differ only slightly in appearance.[2]

T. m. singetra, described by Finn Salomonsen in 1933, is found in northern, western and southern Madagascar.[2]
T. m. mutata, described by Linnaeus in 1766, is found in the east and on the High Plateau of Madagascar.[2]
T. m. comorensis (sometimes misspelled comoroensis), described by Alphonse Milne-Edwards and Émile Oustalet in 1885, is found on Grand Comoro.[2]
T. m. voeltzkowiana, described by Gustav Stresemann in 1924, is found on Mohéli.[2]
T. m. vulpina, described by Edward Newton in 1877, is found on Anjouan.[2]
T. n. pretiosa, described by René Primevère Lesson in 1847, is found on Mayotte.[2]

Malaysian Pied Fantail (Rhipidura javanica)

by birdinfo • February 19, 2014 • 0 Comments

The Malaysian Pied Fantail (Rhipidura javanica) is a species of bird in the fantail family. It is locally referred to as muria gila, literally “crazy thrush” in the Malay language.[2] It is found in Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar,Singapore, Thailand, and Vietnam. Its natural habitat is subtropical or tropical moist lowland forests.

The fantails are small bodied (11.5–21 cm long) birds with long tails; in some species the tail is longer than the body and in most the tail is longer than the wing.[1] When the tail is folded it is rounded at the end, but when spread in display or aerial foraging it has a characteristic fan shape that gives the family its name.

Fantails adopt a hunched horizontal posture most of the time, with the wings drooped and held away from the body and the tail half cocked. There are some exceptions to this, particularly theNorthern Fantail of New Guinea and the Cockerell’s Fantail of the Solomon Islands, which have a more upright posture reminiscent of the monarch flycatchers.

The wings of fantails are tapered and have sacrificed speed for agility, making fantails highly efficient at catching insect prey. Overall the fantails are strong fliers, and some species can undertake long migrations, but the thicket-fantails (Sooty Thicket-fantail, White-bellied Thicket-fantail and Black Thicket-fantail) are very weak fliers, and need to alight regularly.

The bills of fantails are typical for aerial insect eating birds, being flat and triangular. The gape is surrounded by two rows of rictal bristles which are long, often as long as the bill. The bills of most species are fairly weak, limiting fantails to softer insects, although the more terrestrial Willie Wagtail has a stronger bill.

The plumage of most fantails shows some variation, most species are relatively uniform with some markings.[1] A few species, such as the Rennell Fantail, have uniform plumage, while others have striking if sombre patterns. The colours of most species are greys, blacks, whites and browns, although a few species have yellow or even striking blue feathers. In most species there is nosexual dimorphism in plumage; the notable exception being the Black Fantail of New Guinea where the male has all-over black plumage and the female is almost entirely rufous. In a few species, such as the New Zealand Fantail, there exist two colour morphs, the common pied morph and the rarer black morph (which is most common on the South Island).

Mandarin Duck (Aix galericulata)

by birdinfo • February 19, 2014 • 0 Comments

The Mandarin Duck (Aix galericulata), or just Mandarin, is a medium-sized, East Asian perching duck, closely related to the North American Wood Duck. It is 41–49 cm long with a 65–75 cm wingspan.

The adult male is a striking and unmistakable bird. It has a red bill, large white crescent above the eye and reddish face and “whiskers”. The breast is purple with two vertical white bars, and the flanks ruddy, with two orange “sails” at the back. The female is similar to female Wood Duck, with a white eye-ring and stripe running back from the eye, but is paler below, has a small white flank stripe, and a pale tip to its bill. The Mandarin ducklings are almost identical in look to Wood ducklings, and appear very similar to Mallard ducklings. The ducklings can be distinguished from Mallard ducklings because the eye-stripe of Mandarin ducklings (and Wood ducklings) stops at the eye, while in Mallard ducklings it reaches all the way to the bill. There are various mutations of the Mandarin Duck found in captivity. The most common is the white Mandarin Duck. Although the origin of this mutation is unknown, it is presumed that the constant pairing of related birds and selective breeding led to recessive gene combinations leading to genetic conditions including albinism. The species was once widespread in eastern Asia, but large-scale exports and the destruction of its forest habitat have reduced populations in eastern Russia and in China to below 1,000 pairs in each country; Japan, however, is thought to still hold some 5,000 pairs.

Specimens frequently escape from collections, and in the 20th century a large feral population was established in Great Britain; more recently small numbers have bred in Ireland, concentrated in the parks of Dublin. There are now about 7,000 in Britain, and other populations on the European continent, the largest in the region of Berlin.

Isolated populations exist in the United States. The town of Black Mountain, North Carolina has a limited population,[6] and there is a free-flying feral population of several hundred mandarins in Sonoma County, California. This population is the result of several mandarin ducks escaping from captivity, then going on to reproduce in the wild.

Northern Flicker (Colaptes auratus)

by birdinfo • February 18, 2014 • 0 Comments

The Northern Flicker (Colaptes auratus) is a medium-sized member of the woodpecker family. It is native to most of North America, parts of Central America, Cuba, the Cayman Islands, and is one of the few woodpecker species that migrate. There are over 100 common names for the Northern Flicker. Among them are: Yellowhammer, clape, gaffer woodpecker, harry-wicket, heigh-ho, wake-up, walk-up, wick-up, yarrup, and gawker bird. Many of these names are attempts at imitating some of its calls.

The Northern Flicker is part of the genus Colaptes which encompasses 12 New-World woodpeckers. There are two living and one extinct subspecies of C. auratus. The existing sub-species were at one time considered separate species but they commonly interbred where ranges overlap and are now considered one species by the American Ornithologists Union. Whether or not they are separate species is a well-known example of the species problem.

The Yellow-shafted Flicker (Colaptes auratus auratus) resides in eastern North America. They are yellow under the tail and underwings and have yellow shafts on their primaries. They have a grey cap, a beige face and a red bar at the nape of their neck. Males have a black moustache. Colaptes comes from the Greek verb colapt, to peck. Auratus is from the Latin root aurat, meaning “gold” or “golden” and refers to the bird’s underwing.

Under the name “Yellowhammer” it is the state bird of Alabama.[2]

The Red-shafted Flicker (Colaptes auratus cafer) resides in western North America. They are red under the tail and underwings and have red shafts on their primaries. They have a beige cap and a grey face. Males have a red moustache. The scientific name, Colaptes auratus cafer, is the result of an error made in 1788 by the German systematist, Johann Gmelin, who believed that its original habitat was in South Africa among the Xhosa people, then known as the “Kaffir” people.

The †Guadalupe Flicker (Colaptes auratus/cafer rufipileus) extinct c. 1910.

Tufted Puffin (Fratercula cirrhata)

by birdinfo • February 18, 2014 • 0 Comments

The Tufted Puffin (Fratercula cirrhata) also known as Crested Puffin, is a relatively abundant medium-sized pelagic seabird in the auk (Alcidae) family found throughout the North Pacific Ocean. It is one of three species of puffin that make up theFratercula genus and is easily recognizable by its thick red bill and yellow tufts.

Tufted Puffins are around 35 cm (15 in) in length with a similar wingspan and weigh about three quarters of a kilogram (1.6 lbs). Birds from the western Pacific population are somewhat larger than those from the eastern Pacific, and male birds tend to be slightly larger than females. They are mostly black with a white facial patch, and, typical of other puffin species, feature a very thick bill which is mostly red with some yellow and occasionally green markings. Their most distinctive feature and namesake are the yellow tufts (Latin: cirri) that appear annually on birds of both sexes as the summer reproductive season approaches. Their feet become bright red and their face also becomes bright white in the summer. During the feeding season, the tufts moult off and the plumage, beak and legs lose much of their lustre. Ats among other alcids, the wings are relatively short, adapted for diving, underwater swimming and capturing prey rather than gliding, of which they are incapablele. As a consequence, they have thick, darkmyoglobin-rich breast muscles adapted for a fast and aerobically strenuous wing-beat cadence, which they can nonetheless maintain for long periods of time. Juvenile Tufted Puffins resemble winter adults, but with a grey-brown breast shading to white on the belly, and a shallow, yellowish-brown bill.[2] Overall, they resemble a horn-less and unmarkedRhinoceros Auklet (Cerorhinca monocerata).
