The common crow is a large, blue-black bird that grows up to almost two feet long. It can be found living in almost every state and is a year-round resident in New England. These highly adaptable animals are commonly identified by their “caw-caw“ cry. They live in multiple habitats ranging from farmland to suburban neighborhoods, as long as they can find shelter and suitable trees for nesting.
Crows are omnivorous and eat grains, insects, carrion, eggs, reptiles, fish, vegetable matter and young birds.
Crows breed in the early spring, and can often be seen carrying building materials such as bark and twigs back to their nests. The nests are lined with soft materials like cloth, feathers and grass. Nests are usually built fifteen or twenty feet high in a tree, although on rare occasions a nest is made on the ground.
The female lays between four to six eggs, which are then incubated by both the male and female for approximately eighteen days. The young are cared for in the nest for a month before they are ready to leave the nest and feed with the adults. The family unit stays together during the summer and joins other families as the fall approaches.

The most important public health concern associated with crows is the accumulation of fecal droppings at roosts. Histoplasmosis spores can be inhaled at roosting sites of birds and bats. There are five forms of histoplasmosis that are clinically recognizable, ranging from a mild hypersensitivity to a disease that mimics chronic pulmonary tuberculosis. Children are especially susceptible to the disease and if contact is suspected they shoudld seek immediate medical care.
