Birds are a group of warm-blooded vertebrates constituting the class Aves, characterized by feathers,toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton.
The long-wattled umbrellabird (Cephalopterus penduliger) is an Umbrellabird in the Cotinga family. Its common names include "Pájaro Bolsón", "Pájaro Toro", "Dungali" and "Vaca de Monte".The Long-wattled Umbrellabird is considered rare and it resides in humid to wet premontane and cloud forest.
The all-black male Long-wattled Umbrellabird gets its name from the crest of fine, hair-like feathers that hang all the way over its bill (like an umbrella). That must come in handy when it rains!
There are alot of birds estimated to be about 200 to 400 billion individual birds according to two scientists who decided to estimate the total number of birds on the planet about 10 years ago.
Comparing that to humans; about 5 billion people, this amounts to about 40 to 60 birds per person.
