The answer to this depends on what type of bird feeder you have and what kind of birds you're trying to attract. For example, a wild bird feeder would be better placed somewhere farther away from the home, so that the wild bird feels more comfortable in reaching and eating the bird seed itself.
Meanwhile, a tube feeder can usually be placed anywhere, where there is enough hanging space for the tube feeder to sit freely. Just be sure there's plenty of space surrounding the feeder too, so that the drainage holes can work effectively. Not only this, but it needs to be fairly visible in order to help you feed wild birds without attracting squirrels.
Ground feeders, on the other hand, come with an additional risk of having prey not only seek out food from the feeding ports - but also to get to the birds themselves. As such, the best bird feeders' placements for these feathery friends are somewhere that can avoid any feline foes or otherwise.
