Diane an I enjoyed your message about yellow-rump mimics etal.  Sunday morning she and I walked the C&O Canal for a few hours -- the trees were LOUSY with butter-butts!  We'd see some promising movement only to see yet another.
We managed to find a few Parulas, a Palm, Black and Whites, but most were butter-butts.
Thanks for an entertaining post!
