Observations of Predation and Anti-Predator Behavior of Rubythroated Hummingbirds During Migratory Stopover

Predation is not thought to contribute significantly to adult hummingbird mortality in temperate areas, where most reported cases of mortality are the result of accidents (e.g., window collisions and spider webs). However, the hazards encountered during migration, including the threat of predation,...

Summary:Predation is not thought to contribute significantly to adult hummingbird mortality in temperate areas, where most reported cases of mortality are the result of accidents (e.g., window collisions and spider webs). However, the hazards encountered during migration, including the threat of predation, can impact hummingbirds while on stopover. We present one account of predation upon Archilochus colubris (Ruby-throated Hummingbird) by Accipiter striatus (Sharp-shinned Hawk) and one account of a Ruby-throated Hummingbird displaying anti-predator behavior by mobbing a Falco sparverius (American Kestrel). All observations took place in coastal Alabama during stopover in autumn.
