House Sparrow

Passer domesticus

Introduced to North America in the mid-1800s by European settlers, this bird is an extremely adaptable species. Its success is very closely linked with humans, as it eats various types of grains and prefers to nest in and around human structures, such as roof eaves, rather than naturally occurring spots. They can often be seen gathered together in flocks and are very social. The males have gray and rusty brown areas on the head along with a black chest patch, while the female is more uniformly brownish gray.
