An adult Golden-crowned Sparrow was found and identified by Ellen Blanchard this morning. I spent most of my time studying this bird as it fed around her yard. The bird did one time perch on a hook stand and take suet. The Golden-crowned was rather dominant among the sparrows here, several times bumping, fighting and winning against White-throated Sparrows. A medium-large Zonotrichia sparrow with overall dark coloration of browns and grays. The crown had two, broad, black lateral crown stripes that narrowly met across the forehead. Between these stripes there was a yellow median crown patch that extended back to mid crown, this was not as bright yellow as some spring adult males, but bright nonetheless. Behind the yellow patch, the median area of the crown was whitish gray. On the nape, the two black lateral stripes transitioned to narrower dark brown stripes that were short and ended at the neck. The face was ashy gray and a fairly prominent white crescent subtended the eye. Each black lateral crown stripe had a few small areas of grayish, and there was a small area of yellow in the black above the right eye. The back was striped with black and light brown lines, the pale brown stripes less tawny than the similar pale stripes on White-throats. The lower back, rump, and uppertail coverts were medium brown. The wings were brown and showed medium primary projection. The greater coverts and tertials were black centered with rich brown borders. The median and greater coverts were tipped with white on the outer web only, producing dot-like wing bars. The tail was dark brown, the central rectrices appearing somewhat darker than the lateral rectrices. The chin and throat were whitish gray, and the malars stood out as slightly paler, these subtended by obscure dusky submalar streaks. The breast was medium, ashy gray, and this transitioned to an off-white and dingy abdomen. The flanks were medium but bright brown, blending with the breast and center of abdomen. The undertail coverts were tawny brown and the undertail coverts showed darker brown centers; the undertail coverts contrasted moderately with the whiter vent. The irides were dark brown. The legs were dull reddish to pinkish-brown. The bill was dark (slaty?) on the maxilla, and paler (whitish horn) on mandible. I never heard the bird call. This is at least the fifth record for Maine (three previous reports supported by photos; several sight reports, some lacking details, would bring state total to eight records if all were correct). The species is very rare in the East and Northeast, with most records in mid-late spring (mostly mid May) and fall, with a few records of wintering birds.
