Similar
species and
how were they eliminated: |
My primary focus was eliminating a Townsend's X Hermit hybrid, and I believe
this is a clean Hermit, due to the lack of yellow extending through throat and down onto breast and the lack of streaks on the sides. Other characters (buffy flanks, brownish rather than green back) also tend to rule out a "HETO" warbler. |
Previous
experience with this & similar species: |
This is my second Hermit Warbler in Washington County, however I've seen them several times elsewhere. Familar with more regularly occuring warblers. |
References consulted: | I looked for Hermit X Townsend's hybrid descriptions in Dunn and Garrett 1997 (Warblers), Curson, Quinn, and Beadle 1994 (Warblers of the Americas), and Eckert 2001 (Hermit/Townsend's Hybrids, Birding 35(4)). |
