UNDERTAIL COMPARISON BETWEEN PROTHONOTARY AND WILSONS WARBLER'S

Many times the best or only look that you can get can be from below or behind a bird.  This can often be enough for a good ID.
Warblers are particularly challenging because they  usually like thicker cover.
    Here we compare undertails of Prothonotary Warbler vs Wilson's Warbler. (Wilson's is all yellow underneath)
