Geographic range
Distribution. Blue = A. p. piscivorus; Red = A. p. conanti, Green = A. p. leucostoma, Gray = intergradation.[4]Found in the eastern United States from Virginia, south through the Florida peninsula and west to Arkansas, southeastern Kansas, eastern and southern Oklahoma, and east and central Texas. A few records exist of the species being found along the Rio Grande in Texas, but these are thought to represent disjunct populations, now possibly eradicated. The type locality given is "Carolina," although Schmidt (1953) proposed that this be restricted to the area around Charleston, South Carolina.[1]
Campbell and Lamar (2004) mentions this species as being found in Alabama, Arkansas, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Mississippi, Missouri, North Carolina, Oklahoma, South Carolina, Texas, and Virginia.[4] Maps provided by Campbell and Lamar (2004) and Wright and Wright (1957) also indicate its presence in eastern Tennessee, extreme southeastern Nebraska and limit it to the western part of Kentucky.[3][4]
In Georgia it is found in the southern half of the state up to a few kilometers north of the fall line with few exceptions. Its range also includes the Ohio River Valley as far north as southern Illinois, and it inhabits many barrier islands off the coasts of the states where it is found.[4]
