I am not sure if I am doing the birds I am feeding a favor or not. They are continually being harassed, and no doubt eaten, by a female sub adult Cooper's and an adult male Sharp-shinned, as well as two neighborhood cats. And then there is the White-throated that did itself in on the back glass; likely attempting to escape one of the fore mentioned. I have been feeding some black walnut kernels that have gotten old; tossing a few a day. The resident Mockingbird has decided they are his/hers. It is rather interesting that it swallows whole no matter what the size. Clearly a full gut is the important factor and not taste fulfillment.
