Abstract:Colonially nesting cliff swallows, Hirundo pyrrhonota, in southwestern Nebraska use a vocal signal, termed the squeak call, which alerts conspecifics that food has been found. Birds were recruited to playbacks of this call, and the frequency of calling increased when insect swarms were provided to the swallows. Squeak calls were used mostly while birds were foraging in loose groups away from their colonies. Calling occurred primarily on days when temperatures were less than 17
