this came from birds and blooms - george's corner - page 19 of 2010 sometime i believe....
clean out all birdhouses - use soap and water to remove parasites and insects; leave at least one house out for winter roosting.
collect fall clippings - to create brush piles that will protect ground birds and other wildlife in winter.
shut down birdbaths and ponds - after the last migrants have passed through, unless you live in a frost free zone. otherwise and electric birdbath heater may be used to attract thirsty birds. don't worry about birds freezing their feathers. they know not to bathe in subfreezing weather.
set up hopper style feeders - which are more practical than tray feeders when the moisture from rain and snow can ruin food.
protect stored bird food - by securing it in waterproof garbage cans. use bricks and bungee cords on lids to keep out raccoons and squirrels.
