I came home today to find that a male Ruby-throat has discovered the feeder! He is now perching just above the feeder on a overhanging treebranch, his apparent guardpost. Problem is, he is trying to chase off the two females who have been (more or less) cooperatively sharing the feeder. They, however, are not taking this lightly; they chase him plenty too, and I half expect them to gang up on him any minute now. To add to his troubles, there is a finch feeder I have hanging nearby, and the hummies and finches take turns chasing one another off now and then near the "look out perch." It's rather amusing, actually. Am enjoying the Hummies this year, obviously :) Irene in Southside
