The sharp-shinned hawk is an accipiter. The accipiter family includes sparrowhawks, which we do not usually see in North America, goshawks, and a few other hawks including the sharp-shinned and coopers hawks. Accipiters have broad, short wings and a long tail which helps them maneuver when they fly. Accipiters also have relatively long legs which come in handy to hunt and capture passerines.
After a while the sharpie flew off and the birds began to return to the feeder.
Even a pileated woodpecker. I think that pileated woodpeckers are pretty cool but when talking to other birders I am never sure which way to pronounce it. Some people pronounce it pill-ee-ay-tid and other people pronounce it Pie-lay-tid. Usually now I call it both, because some birders are crazy and can get hostile if you do not pronounce it the way that they do.Then suddenly all of the birds at the feeder scattered except one lone downy that was stuck frozen at the feeders.I knew that the sharpie was back before I ever saw it.Fortunately he perched in a pretty good spot for me to get some pics before he spotted the left over downy.And the chase was on. Fortunately for the downy he was able to out maneuver the sharpie and escape, this time.
