(Description:) Field Marks and Identifying Characteristics:	Warbler flushed at less than 3m from me. Naked eye it looked too yellow for a YRWA, so I put the binos on it, and was dumbfounded that it was a Northern Parula. Had an entirely bright yellow-orangy throat and breast, with a white belly, bluish head with eye arcs, yellowish patch on the back and 2 white wing bars, presumably an immature as the breast was solid yellow with no darker band of an adult. (see photos)
Song or call & method of delivery:	None heard
Behavior:	Visiting our feeders, feeding on compressed seed of a "woodpeck log"
Habitat:	City Park
Similar species and how were they eliminated:	Yellow-rumped Warbler are superficially similar, but yellow is limited to throat and flanks patch, blackish gray head and back, streaking on the flanks and breast,yellow on crown, and are larger and longer tailed. No other warbler normally winters here. Tropical Parula ruled out by eye arcs.
