Relative Detectability: Difficult to see (due to habit of nesting high in very tall conifers), and song is often confused with that of Townsend's Warbler, with which it often hybridizes. Very difficult to confirm breeding.

Challenge: Refine knowledge of the eastern boundary of its Oregon range. Determine if individuals rarely nest in the Blue Mountains, as suggested by Gilligan et al. (1994).
