American Robin

The American Robin bird breeds throughout most of North America, from Alaska and Canada southward to northern Florida and Mexico. While robins occasionally overwinter in the northern part of the United States and southern Canada, most migrate to winter south of Canada from Florida and the Gulf Coast to central Mexico, as well as along the Pacific Coast.

Eastern Towhee

Eastern towhees seem to prefer sites with characteristics generally associated with early successional vegetation, such as low canopy cover and dense understory. Negative correlations between eastern towhee abundance and various measurements of overstory density have been found in several studies. Average density of eastern towhees across 6 habitat types in Pennsylvania was significantly (p<0.05) negatively correlated with density of overstory trees and basal area of overstory trees.

Fish Crow

Visual differentiation from the American crow is extremely difficult and often inaccurate. Nonetheless, differences apart from size do exist. Fish Crows tend to have more slender bills and feet. There may also be a small sharp hook at the end of the upper bill. Fish crows also appear as if they have shorter legs when walking. More dramatically, when calling, fish crows tend to hunch and fluff their throat feathers.

American Crow

From beak to tail, an American crow measures 40–50 cm (16–20 in), almost half of which is tail. Mass varies from about 300 to 600 g (11 to 21 oz). Males tend to be larger than females. The most usual call is CaaW!-CaaW!-CaaW!.
