Plant bird friendly trees that will bear fruit or nuts as well as providing shelter. Fall is a good time to plant, giving roots a chance to get established before dormancy sets in.
Berries make great treats for your winter birds. Freeze some now and put them out in late winter when most of the fruit or berries on the trees have been eaten.
When making Jack-O-Lanterns, save the seeds. Rinse well to remove the fiber and dry them in a 200° oven. Songbirds will love ‘em (so will chipmunks, OK, squirrels, too!).
