Yesterday smoking on the old porch , watching my Humming Bird feeder , 2 little birds started bumping into each other, then they locked up in flight, thought it was a Boy, Girl thing, but No, they started corkscrewing down, down, and hit the ground. Those little SOBs were fighting, so I read up on those little suckers, seems they are very protective of their feeders.wife went into town today and bought another one. Hung it up and waiting if they will eat and make up. LOL
