摘要

Unlike most birds, brood parasitic Brown-headed Cowbirds (Molothrus ater) must find Host nests in which to lay their eggs. Female cowbirds Have been reported using several methods to find nests. Here, I report on tow observations of cowbirds near Host nests that are consistent with two hypotheses, Nesting-cue and "flush" method, regarding techniques Cowbirds may use to find host nests. The nesting-cue Hypothesis poses that cowbirds are directed to host Nests by host's typically increasing aggressive behavior Towards cowbirds as they approach the nest, whereas The flush method poses that cowbirds attempt to spot A concealed nest by rousing the host from it with in- Tentionally noisy behavior near the nest.
