We have some great tips in this site where you can make
your own feeders to attract birds to your bird feeding station. These work great but if you want to get a more natural-looking bird photograph, you probably don't want to have it perched on a feeder.
A simple solution you might want to try is to secure a few twigs near the food source. Be sure the background is appropriate. You don't want a fence post or someone's car there.
