Seed residue can be a problem. To avoid this entirely, use a variety of seed that has had the outside hull removed. Since the birds don’t have to remove the hull from the seed, there’s no hull to fall to the ground. Or to fall on your balcony. The goal, however, is to entice the birds to eat every last seed.
Of course, if a seed is fresh (even if the hull is left on), any that falls to the ground will likely be eaten by ground-feeding birds – like Cardinals. Thrashers and Doves. So, even if the price is a bit more, get the seed that’s freshest from the mill. More of it gets eaten and less of it winds up beneath the feeder. If you can clean up the hulls beneath a feeder, go ahead and buy the less-expensive seed with hulls.
Seed that’s blended especially for our
Of course, nectar feeders (for Hummingbirds) and nut feeders (for almost all birds) make hardly any mess, and are great for small spaces.
