Lovely recent photo by Johann Schumacher shows a young male (note the beginnings of the adult forked tail).
Bill Koller, at Long Island Hummingbird Plants , and his wife Peg came over for their regular Labor Day visit. Of course we discussed all matters hummingbird, and I told him that I was having problems with wasps and bees going for the tiny seeps of nectar where the cap screws on the minifeeders. They also go to the outlet (not Tanger!) but when these stick their head in, I simply quickly (that's the key to avoid being stung) squish them between thumb and forefinger. But those on the seeps (invisible to the naked eye) are more easily able to see and evade their looming doom.
Bill said he dealt with this problem by simple putting plumber's teflon tape on the screw part - brilliant. I tried it out yesterday and it really works. Bill still has some excellent hummer plants for those late arrivals (or, in the case of columbine, for those arriving in the spring.)
