General Comments Unlike the American Crow, the Fish Crow is poorly known to the layman -- "There are two kinds of crows in the state?". Until the 1960's, this might have been understandable, as this species was known only as a common permanent resident in tidal areas. For whatever reason, numbers started spreading inland into the upper reaches of the Coastal Plain by the mid-1960's, including a few spots along the Piedmont Fall Line. Even now (2012), Fish Crows continue to slowly move farther inland, such that birds now are breeding in roughly the eastern and southern 50-60% of the state; and they are reported and possibly breeding in most of the Piedmont except some northwestern counties. A few have been seen in the mountains, but nesting has not yet been documented there. However, the species tends to withdraw back to the Coastal Plain (eastward or southward) for a couple of months in winter. Near the coast, and in many inland areas, they are closely tied to open water -- coastal islands, edges of forests near sounds, and woods adjacent to reservoirs. However, after initial establishment, they often move away from water and feed at landfills and in residential areas, to feed on bird eggs and nestlings, as well as other food off the ground. They avoid feeding in farmland and other cropland, at least in the Piedmont, leaving these areas to the American Crow. Birds nest in evergreen cover of pine stands, broadleaf evergreen forests and thickets, etc. In fall and winter, they typically gather into larger flocks (often over 100 birds) than are the flocks of American Crows; the two species seldom occur in the same flock.

Coastal Plain Permanent resident over most of the area, with migratory movements; apparently increasing. Generally, common to very common along the coast and in Tidewater, and fairly common to common inland. Can be locally uncommon in some inland areas in winter, especially in the northwestern portions. Because it gathers into large flocks in winter, it can be locally scarce for various periods, even in some coastal areas. Peak counts:
Piedmont Summer resident, remaining into late fall, but seldom overwintering except in mild winters; noticeably increasing. In the warmer months, common along the extreme eastern and southern counties, such as Wake and parts of Mecklenburg; mostly uncommon and local west to Forsyth. Sporadic visitor farther westward to Catawba and Polk, where nesting is uncertain. Remains well into Dec near the Fall Line, returns by early Feb; many Jan records (and such winter records are increasing). Peak counts:
Mountains Sparse migrant/stray; recent arrival, since 2006. Five records for low elevations in the southern mountains (Henderson and Buncombe); only during migration -- 3 Apr - 12 May, and 13 Sep and 6 Oct. Peak counts: 8, Henderson, 12 May 2009.
Finding Tips Easy to find, and not local, in the breeding season, in most of the Coastal Plain, especially around salt or brackish water.
