High Time For a Hawk Visit

One of the benefits of the Great Backyard Bird Count (which ends today) is that all the extra time spent intensively watching feeder activity can add up to new discoveries. My latest isn't good news. I had been puzzling over severe drops in feeder activity especially in February. I wondered if an aggressive Northern Mockingbird might be the problem, as one of several theories. Right idea. Wrong culprit. While the Mockingbird did show evidence of some aggressiveness at the peanut butter feeder, he is a piker next to this guy. A spectacularly aggressive Yellow Rumped Warbler drove off everything in sight, even birds which are not food competitors. He chased off House- and Goldfinches, Kinglets, nuthatches, and other Yellow Rumpeds, and now and then harassed Downy Woodpeckers and Northern Cardinals. I can't tell how many others he's driven off for good because most of my data are coming "now that the barn doors are closed." But the Eastern Bluebirds, Hermit Thrush, and Carolina Chickadees are very good bets. To my astonishment, this bully also chased off birds at other feeder stations including my back neighbors'! I now have several hours of intensive observation and all is explained. Unfortunately, this character is going to be around for some weeks more and unless an opportunistic hawk catches him in his risky solo Tarzan act I am concerned my feeders are going to be very quiet places. Other birds will eventually weary of the harassment and move on. So how about it, Red Tailed Hawk? Are you game?
