A pumpkin carved into a jack-o-lantern shouldn't be trashed automatically after halloween. Yes, a carved pumpkin rots more quickly than a whole one. But it's already at your home and paid for. Also keep in mind that many "pumpkin patches" sell leftover pumpkins (starting the day after halloween) cheaply. If carved pumpkins rot too quickly in whatever weather we have in north Texas, consider using your fall pumpkins to make a pumpkin birdfeeder. Just add a little seed to any remaining pumpkin seeds and put it outside. Whichever way you go, carved or whole, remember that birds are attracted to seeds, including pumpkin seeds.
If using an already-carved one, just carve out the "face". Then fill with fresh birdseed. This simple bird feeder can be used anywhere you would normally use tray or platform feeders. If you use hay bales as part of your outdoor fall decorations, placing one of these feeders between hay bales or on top of a hay pile adds a touch of color and active bird interest. A pile of whole pumpkins can also be easily accented with the addition of a carved pumpkin bird feeder. Note: Placing the feeder in the shade will help it last longer.
