American Tree Sparrow

Spizella arborea

American Tree Sparrows are widespread breeders throughout the state of Alaska but have not shown a historic tendency to wander into the Bering Sea. Five American Tree Sparrow have made their way to Saint Paul Island. The first two were found in spring, on May 21 and June 3, 1998. The third and fourth birds were found from September 23-25, 2003, and the fifth record comes from August 27, 2004. It is likely that with more thorough coverage of the Pribilofs in fall this species will prove to be more regular. The clear breasted, gray faced, and rufous crowned adults (often with a prominent black breast spot) are straightforward to identify but fall juveniles should be looked at closely as they could be confused with other Spizellas.
