PARQUE DE AVES

Toucans range in size from the Lettered Aracari (Pteroglossus inscriptus), at 130 g (4.6 oz) and 29 cm (11.5 inches), to the Toco Toucan (Ramphastos toco), at 680 g (1.5 lb) and 63 cm (29 inches). Their bodies are short (of comparable size to a crow's) and compact. The tail is rounded and varies in length, from half the length to the whole length of the body. The neck is short and thick. The wings are small, as they are forest-dwelling birds who only need to travel short distances, and are often of about the same span as the bill-tip-to-tail-tip measurements of the bird.

It can reach 76–86 cm (29.9-33.9 inches) long and weigh 900 to 1300 g (2-3 lbs). It is vivid in appearance with blue wings and tail, dark blue chin, golden under parts and a green forehead. Its beak is black, and very strong for crushing nuts. The naked face is white, turning pink in excited birds, and lined with small black feathers.

The Blue-and-yellow Macaw (Ara ararauna), also known as the Blue-and-gold Macaw, is a member of the group of large Neotropical parrots known as macaws. It breeds in forest (especially varzea, but also in open sections of Terra Firme) and woodland of tropical South America from Trinidad and Venezuela south to Brazil, Bolivia, Colombia, and Paraguay. It barely extends into Central America, where restricted to Panama. It is an endangered species in Trinidad, and is on the verge of being extirpated from Paraguay, but still remains widespread and fairly common in a large part of mainland South America. There is also a breeding population in Miami-Dade County, USA. It is therefore listed as Least Concern by BirdLife International.

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, and appears to be due to environmental factors.[citation needed] The Blue-and-yellow Macaw uses its powerful beak for breaking nutshells, and also for climbing up and hanging from trees.
