Blue Fronted Amazon Parrot


The Blue-fronted Amazon is a mainly green parrot about 38 cm (15 in) long. They have blue feathers on the forehead above the beak and yellow on the face and crown. Distribution of blue and yellow varies greatly among individuals. Unlike most other Amazona parrots, its beak is mostly black. There is no overt sexual dimorphism in plumage to the human eye, but analysis of the feathers using spectrometry, a method which allows the plumage to be seen as it would be by a parrot's tetrachromatic vision, shows clear differences between the plumage of the sexes.Juveniles of parrots are duller and have dark irises.

African Grey Parrot


The African Grey Parrot (Psittacus erithacus), also known as the Grey Parrot, is a medium-sized parrot found in the primary and secondary rainforest of West and Central Africa. Experts regard it as one of the most intelligent birds in the world. They feed primarily on palm nuts, seeds, fruits, and leafy matter, but have also been observed eating snails. Their overall gentle nature and their inclination and ability to mimic speech have made them popular pets, which has led many to be captured from the wild and sold into the pet trade. The African Grey Parrot is listed on CITES appendix II, which restricts trade of wild-caught species because wild populations cannot sustain trapping for the pet trade.

American Robin

The nominate subspecies of the American Robin is 23 to 28 cm (9.1 to 11 in) long with a wingspan ranging from 31 to 41 cm (12 to 16 in), with similar size ranges across all races. The species averages about 77 g (2.7 oz) in weight, with males ranging from 72 to 94 g (2.5 to 3.3 oz) and females ranging from 59 to 91 g (2.1 to 3.2 oz).Among standard measurements, the wing chord is 11.5 to 14.5 cm (4.5 to 5.7 in), the culmen is 1.8 to 2.2 cm (0.71 to 0.87 in) and the tarsus is 2.9 to 3.3 cm (1.1 to 1.3 in).[The head varies from jet black to gray, with white eye arcs and white supercilia.The throat is white with black streaks, and the belly and undertail coverts are white. The Robin has a brown back and a reddish-orange breast, varying from a rich red maroon to peachy orange.The bill is mainly yellow with a variably dark tip, the dusky area becoming more extensive in winter, and the legs and feet are brown.

The sexes are similar, but the female tends to be duller than the male, with a brown tint to the head, brown upperparts and less bright underparts. However, some birds cannot be safely sexed on plumage alone.The juvenile is paler in color than the adult male and has dark spots on its breast,and whitish wing coverts.First-year birds are not easily distinguishable from adults, but they tend to be duller, and a small percentage retains a few juvenile wing coverts or other feathers.

Red fronted Macaw Parrot

The Red-fronted Macaw is native to a small mountainous area of south-central Bolivia situated about 200 km west of Santa Cruz, in the department of the same name, where the climate is medium altitude semi-desert. The natural vegetation consists mostly of cactus (large and small) and thorny trees and scrub. The climate is semi arid with cold nights and hot days. Rain comes in infrequent heavy storms. It is unusual in that it is the only macaw to inhabit such a climatic zone. Most macaws nest in holes in large trees, however here there are no very large trees in its range so it nests in vertical fissures in cliff faces.The bird has been captured for the pet trade in the past and killed by local farmers because it raids their crops.

Northern Cardinal of Christmas

The Northern Cardinal is a mid-sized songbird with a body length of 20–23.5 cm (7.9–9.3 in) and a wingspan of 25–31 cm (9.8–12 in). The adult weighs from 33.6–65 g (1.19–2.3 oz), with an average 44.8 g (1.58 oz).The male averages slightly larger than the female.The adult male is a brilliant crimson red color with a black face mask over the eyes, extending to the upper chest. The color becomes duller and darker on the back and wings.The female is fawn, with mostly grayish-brown tones and a slight reddish tint on the wings, the crest, and the tail feathers.The face mask of the female is gray to black and is less defined than that of the male. Both sexes possess prominent raised crests and bright coral-colored beaks. The beak is cone-shaped and strong.[8] Young birds, both male and female, show the coloring similar to the adult female until the fall, when they molt and grow adult feathers.They are brown above and red-brown below, with brick-colored crest, forehead, wings, and tail.The legs and feet are a dark pink-brown. The iris of the eye is brown.The plumage color of the males is produced from carotenoid pigments in the diet.Coloration is produced from both red pigments and yellow carotenoid pigments.Northern Cardinal males possess the ability to metabolize carotenoid pigments to create plumage pigmentation of a color different from the ingested pigment. When fed only yellow pigments, males become a pale red color, rather than a yellow.

Wilson's Bird-of-paradise


The Wilson's Bird-of-paradise, Cicinnurus respublica, is a small, up to 21 cm long, passerine bird of the Paradisaeidae family. The male is a red and black bird-of-paradise, with a yellow mantle on its neck, light green mouth, rich blue feet and two curved violet tail feathers. The head is naked blue, with black double cross pattern on it. The female is a brownish bird with bare blue crown.

In the field, the blue bare skin on the crown of the bird's head is so vivid that it is clearly visible by night; the deep scarlet back and velvet green breast are lush, the curlicue tail gleaming bright silver.

An Indonesian endemic, the Wilson's Bird-of-paradise is distributed to the hill and lowland rainforests of Waigeo and Batanta Islands off West Papua. The diet consists mainly of fruits and small insects.

Blue and Yellow Macaw

These birds can reach 76 to 86 cm (30 to 34 in) long and weigh 900 to 1500 grams (1.9 to 3.3 lbs), making it one of the larger members of its family. They are vivid in appearance with blue wings and tail, dark blue chin, golden under parts, and a green forehead. Beaks are black. The naked face is white, turning pink in excited birds, and lined with small black feathers.

There is little variation in plumage across the range. Some birds have a more orangey or "butterscotch" underside color, particularly on the breast. This was often seen in Trinidad birds and others of the Caribbean area. The Blue-and-yellow Macaw uses its powerful beak for breaking nutshells, and also for climbing up and hanging from trees.

Scarlet Macaw Parrot Picture

It is about 81 centimetres (32 in) long, of which more than half is the pointed, graduated tail typical of all macaws, though the Scarlet Macaw has a larger percentage of tail than the other large Macaws. The average weight is about 1 kilogram (2.2 lb). The plumage is mostly scarlet, but the rump and tail-covert feathers are light blue, the greater upper wing coverts are yellow, the upper sides of the flight feathers of the wings are dark blue as are the ends of the tail feathers, and the undersides of the wing and tail flight feathers are dark red with metallic gold iridescence. Some individuals may have green in the wings.


There is bare white skin around the eye and from there to the bill. Tiny white feathers are contained on the face patch. The upper mandible is mostly pale horn in color and the lower is black. Juveniles have dark eyes; adults have light yellow eyes.

It is frequently confused with the slightly larger Green-winged Macaw, which has more distinct red lines in the face and no yellow in the wing.

Scarlet Macaws make very loud, high and sometimes low-pitched, throaty squawks, squeaks and screams designed to carry many miles to call for their groups.

The Scarlet Macaw can live up to 75 years in captivity, although a more typical lifespan is 40 to 50 years.

Hyacinth Macaw Parrot


The Hyacinth Macaw survives today in three main populations in South America: In the Pantanal region of Brazil, and adjacent eastern Bolivia and northeastern Paraguay, in the Cerrado region of the eastern interior of Brazil (Maranhão, Piauí, Bahia, Tocantins, Goiás, Mato Grosso and Minas Gerais), and in the relatively open areas associated with the Tocantins River, Xingu River, Tapajós River, and the Marajó island in the eastern Amazon Basin of Brazil. It is possible that smaller, fragmented populations occur in other areas. It prefers palm swamps, woodlands, and other semi-open wooded habitats. It usually avoids dense humid forest, and in regions dominated by such habitats, it is generally restricted to the edge or relatively open sections (e.g. along major rivers). In different areas of their range these parrots are found in savannah grasslands, in dry thorn forest known as 'caatinga', and in palm stands,particularly the Moriche Palm (Mauritia flexuosa).
