Abstract
Pyrotechnics have long been used to frighten birds from specific areas but birds might ha-bituate to them. Anecdotal and limited published reports suggest that killing a flock member can reduce habituation. However, little behavioral work has been conducted in this area. We exposed brown-headed cowbirds (Molothrus ater) to noise from either 0.22 caliber blanks or 15-mm pyrotechnics in a series of controlled, cage experiments to determine if killing a flock member increased the time that cowbirds re-spond to pyrotechnics. Cowbirds responded no differently to pyrotechnics following the death of a flock member either before or after habituation to pyrotechnics. Our results might have been influenced by cage effects or perceived inconsequence of the death of a conspecific. Further work with other species is warranted, particularly with regard to sociality.
