Caption
If intruders ignore his one-note warning, a male gets more aggressive and challenges them with a severe tongue lashing ! This routine is so effective that after a few days, virtually no other hummers come into his area and all he needs to do to maintain it is sing his one-note samba. Rufous hummers are both aggressive and intolerant of other species at the feeder. His wingbeat here measures a fairly fast 60 bps.
