Wilson's warbler in Maryland in late December

On December 22, 1947, while participating in a Christmas Bird Count on the eastern shore of Maryland, I observed a Wilson's warbler ( Wilsonia pusilla ) feeding along a sunny margin of a woods near the Pocomoke River, three miles north of Snow Hill. It was with a flock of myrtle warblers ( Dendroica coronata ), white-throated sparrows ( Zonotrichia albicollis ), Carolina chickadees ( Parus carolinensis ), and several other species. My attention was first attracted to the Wilson's warbler by the distinctive call note which it repeated about once a minute. The bird was actively feeding among the dead leaves on a group of young oak trees. The bird was collected and proved to be a female. The skin was preserved for the collection of the Fish and Wildlife Service. The stomach was full, and the contents were identified by Robert T. Mitchell as: fragments of Araneida, 80 per cent; Coleoptera, 10 per cent; Hymenoptera, 10 per cent.
