Free For All!!

I'm suspecting that my neighbor puts something addictive into his bird seed, although he laughs & denies it! Every day as I back into the driveway after work I see FLOCKS of sparrows fighting to get to his bird feeder! Today there were at least 2 dozen on the roof of his garage, about another dozen on the ground under the feeder, another half dozen on the small table in his yard & again as many on his storage container. The sparrows randomly fly over to the feeder to try to get a perch, & if one of it's buddies won't move to make room for them they just knock them off! There's constant motion--constant chaos--at the feeder until about 7:00 p.m. when they slowly disappear for the day. There's an "incoming" bird on the upper left & if you look closely toward the bottom of the feeder you'll see one bird has tried to knock another off the perch & is now giving him an earful! The knocked off one (bottom left) is barely hanging on! You HAVE to look large so you can see all the action up close & personal! :))
