I don't really know the relative status of gambelii versus leucophrys White-crowned Sparrows in the area, but since the latter predominated I report that there was one, possibly two, Gambel's White-crowned Sparrows in the Dark Corners, Monroe County, area 11 Nov (tape recorded song) and 19 Nov (ph). The adult Gambel's were identified by their clean, pale lores, their orange bill, and their song (see PDF of notes). The Gambel's also had a grayer nape and paler back stripes. See digital photos from 19 Nov:
