| Résumé : | We describe a breeding male Blackpoll Warbler (Dendroica striata) in aberrant female-like plumage captured on Mt. Mansfield, Vermont, in 1998. The bird had been banded the previous summer in typical alternate-male plumage. This appears to represent the first documentation of a wild adult male bird in female-like alternate plumage. We suspect that the abnormal plumage reported here was due to hormonal influences on pigmentation. The bird's between-year change in appearance appeared to have no effect on its reproductive behavior. |
