Feeding the birds is something that LSA has done for years; we have an electric heater in one of the bird baths, the other birdbath resembles Snoopy's friend Woodstock hockey rink. Since the hawks have our front yard birdfeeder on their route, it doesn't get near the activity that it once did.
What sort of hawks have you got? Wondering if they are there all the time, or migrate south for winter.
