Apparent fatal snakebite in three hawks.

Based on histories and gross and histologic findings, snakebite was diagnosed in three dead raptors submitted for post-mortem examination from northern Florida and southern Georgia (USA). Two immature red-tailed hawks (Buteo jamaicensis) were found next to dead and partially eaten venomous snakes. An adult Cooper's hawk (Accipiter cooperii) was found adjacent to a den containing a cotton-mouth (Agkistrodon piscivorus) and an eastern diamondback rattlesnake (Crotalus adamanteus). Gross findings in all birds consisted of hemorrhage and gangrenous necrosis of one limb. Severe muscular degeneration was seen histologically.
