Nancy Hunn and I observed a single adult Black-throated Sparrow (Amphispiza bilineata) 16 May 1976 at the Pt. Grenville Coast Guard Station, Grays Harbor Co., Washington. The bird was feeding actively on the lawn of the Coast Guard facility with a flock of about five Savannah Sparrows (Passerculus sandwichensis), three American Goldfinches (Carduelis tristis) and one White-crowned Sparrow (Zonotrichia leucophrys). The Coast Guard Station perches on a high promontory facing the Pacific Ocean and surrounded by second growth coniferous forest typical of the coastal Sitka Spruce (Picea sitchensis) zone (Franklin and Dyrness 1973: 58-63).
Color photographs obtained with the aid of K. C. Johnstone of the U. S. Coast Guard are not of publishable quality but do allow the bird to be identified. Copies of these color slides have been deposited with the Washington Bird Record File at the University of Washington Museum. A sketch drawn while the bird was under observation is also in that file.
