Nest and eggs are very similar to, though a bit smaller than, those of the common crow. Like their cousins, fish crows build their nest in trees. The common raven, Corvus corax , is an uncommon Pennsylvania resident found mainly in the mountainous northcentral region. Once more common, by the late 19th century it was so rare some considered it to be possibly extinct in this state. Today, the raven population is recovering and expanding into the Poconos and our south-central and southeastern counties.
Ravens are abundant in Canada and the Rocky Mountains.
Favored habitat is remote, heavily-forested wilderness, seacoasts and wooded islands. Ravens are 20-25 inches in length, with a wingspread of about four feet. Their plumage is entirely black, with green and purple iridescence. The raven is often confused with its close relative, the crow, but there are major differences between the two species that are especially apparent when crows and ravens are seen together. Ravens eat rodents, insects, grain, fruit, bird eggs and refuse.
