The characteristics of birds are they have feathers. Birds also have backbones which makes them vertebrates. All birds are warm-blooded, they can regulate their body temperature. All female birds lay eggs. Birds also have wings but not all birds use them to fly. Penguins & ostriches are examples of birds that do not fly.
A good things about birds is that they can live in any type of environments. Some live in the coldest environments such as penguins. Other birds live on land in regular conditions. Although all birds can adapt their bodies to any type of weather conditions. For example, penguins keep a high body temperature to remain active in cold conditions. They have thick skin & lots of fat under their skin to keep warm. Birds have different type of food varieties. Since penguins live around water they eat fish & other birds often eat worms.

I chose the Corvidae family. Corvidae is a cosmopolitan family of oscine passerine birds that contain crows, ravens, rooks, jackdaws, jays, magpies, treepies, coughs & nutcrackers. They are also known as the crow family or Corvids. They have over 120 species in this family. The genus Corvus, including the jackdaws, crows & ravens, makes up over a third of the family. They are considered the most intelligent of the birds. Scientists found this out by using mirror & self-awareness tests. Their brain-to-body mass is only slightly lower than humans. Majority of this species are found in tropical South & Central America.
The genus I chose is the Common Raven(corvus corax). It is a large all-black passerine bird. They are found mostly across the Northern Hemisphere. There are at least 8 subspecies of Ravens. They have a lifespan of up to 21 years in the wild. Part of their success comes from their omnivorous diet. They are very versatile in finding sources of nutrition. They feed on carrion, insects, cereal grains, berries, fruit, small animals, & food waste. They are also the largest of the crow family. Ravens call on other animals to do their tasks. Their beaks cannot open tough skins of their prey, so when they cannot do it their selves they make calls that attract wolves & foxes to the site to expose the meat for them.
