On 19 February 2007 at 1723 hrs AST, we saw a Grey Kingbird descend from a tree branch above the front trap and, in mid-flight, steal a moistened dog food pellet from the bill of an adult Carib Grackle that was walking out of the trap.
The Grey Kingbird is a territorial species that aggressively chases other birds and mammals from nesting areas.
Opportunistic feeding behavior may contribute to the success of the Grey Kingbird in Barbados, an island dominated by human-modified habitats.
We observed six acts of interspecific kleptoparasitism by Grey Kingbirds from late February to May 2007 at the Bellairs Research Institute of McGill University in St James, Barbados.
Two Grey Kingbirds were often observed together around the research institute and near the traps, although they were not observed stealing food at the same time.
