All feeders should be constructed by gluing pieces together using nails as well to remain durable. Seal birdhouses with a clear polyurethane varnish to avoid painted houses that chip and peal. Permanent bird feeders should also include easy access to re-fill with food and clean out as necessary. They will also need a way to hang the feeder or a post to mount it on that is high enough to protect birds from predator's. When building a birdfeeder where the bird needs to enter a small opening, you will need to also take into consideration the size of birds you want to feed.
Children can enjoy making disposable, temporary birdfeeders by attaching a wire to a large pinecone.
Another easy Feeder can be made from a coconut. Poke small holes in the coconut and drain out the milk. Wrap a wire through your original drainage holes to create a hanging loop. You can also drive a short piece of dowel into the coconut below the entrance for a perch. Birds are high energy creatures that require a very balanced diet.
