Laughing Falcon (Herpetotheres cachinnans) Predation on Coral Snakes (Micrurus nigrocinctus)1
Authors:Emily H DuVal  Harry W Greene  Katharina L Manno
Abstract:Laughing falcon (Herpetotheres cachinnans) predation on coral snakes (Micrurus nigrocinctus) was recorded in two incidents that illustrate previously unreported variation in predatory behavior. In the first, the falcon held a live coral snake by the posterior end for an extended period of time, rather than decapitating it immediately. In the second, the falcon left a decapitated coral snake in a tree for more than 2 h before returning to recover its prey. A variety of behavioral adaptations may protect laughing falcons from coral snake venom.
