When we get a hard freeze in north Texas (and/or ice storm or snowfall) they'll flock to your feeders enthusiastically. It's important to be ready now, since wild birds will need seed instantly, and won't wait around a day or two - they'll just go to somebody else's feeder.
The leaves on the ground also attract birds, insectivores mainly. The dead leaves harbor millions of tiny bugs. Birds pick through them endlessly for food.
In ensuing years you might want to keep birds in your area by planting what I call "birdscape" plants in your yard. These plants produce seed reliably and in abundance, and provide totally fresh food for birds throughout the fall. The plants are native to this part of Texas, so the very best time to plant them is now (of course you won't see any top-growth until spring, but the roots will be growing like crazy). I'd be glad to send you a list of these plants if you send me your e-mail address.
