Suited to Their Environment
They have the ability to adapt to many
habitats and food sources. Crows live in
environments where it is very common to have
a change of weather. Crows are used to four
seasons a year and just one season a year.
Crows have evolved to be able to live in hot
and cold environments.

Characteristics
Crows have human characteristics. Crows are
curious, observant, sociable, cooperative,
resourceful, intelligent, etc. These
characteristics help them fit into their niche
because they know how to find food, water,
stay away from prey, build a nest, etc.

Evolution
Crows evolved in Asia from the corvid stock. Crows are members of the corvid family. There are five to six species which are almost identical to the crow in Australia.

What is the Crow's future? Is it Extinct Due to Climate Change?
No, climate change will not have a large
impact on the crow. Although the cold weather
may be hard for the crows at first, they can
adjust easily. They have the ability to adapt to
many habitats and food sources.

During the fall and winter they may gather in
very large roosts near a source of food. The
only way that crows have had a rapid decrease
in their population was when they would be
persecuted by humans; which is no longer legal
in the U.S.

What Future Adaptations Will Save It?
Crows are not close to extinction. Owls and
hawks eat crows. A future adaptation that will
help crows will be to blend in easier to hide
from prey.

They even sometimes go after bigger creatures such as amphibians, reptiles, and small mammals. The easiest prey for a crow are caterpillars, scallops, earthworms, mussels, and clams. Another common food for a crow is road kill and waste.
