How Far Should a Bird Feeder Be from a Window?
Closer than you might think. Cornell's All About Birds says feeders are safest placed less than 3 feet from a window, or even attached to the glass, because a bird that leaves the feeder and hits the window is not yet at full speed. This guide covers the distances, the risks in between and products that help.

Quick Answer
Put the feeder closer than 3 feet to the window, or attach it to the glass. All About Birds says this is safest because a bird that hits the window from that short distance is not traveling at top speed and has a better chance of surviving.
Some guides instead advise moving feeders 30 feet or more away. Either way, avoid the middle zone, and add decals or tape to reduce reflections.
What to do about feeders and windows
Four steps, in order of impact.
1. Move the feeder close or far
Place it closer than 3 feet to the window, or fix a window feeder to the glass. If that is not possible, some experts recommend 30 feet or more so birds have room to steer around the glass.
2. Break up reflections
Apply decals or tape on the outside of the glass. American Bird Conservancy's BirdTape instructions call for spacing no farther apart than 2 inches by 2 inches.
3. Keep cover about 10 feet away
All About Birds suggests about 10 feet from trees and shrubs as a compromise: close enough for refuge, far enough that squirrels and cats cannot easily jump to the feeder.
4. Treat reflections at feeding time
If birds still strike the glass, add screens or netting outside, or move the feeder to a window without a large reflection of trees or sky.

Why is a feeder safer close to a window?
A bird that takes off from a feeder less than 3 feet away is not going at top speed when it reaches the glass, so it has a better chance of surviving, according to All About Birds.
How many birds do windows kill?
All About Birds cites estimates that window glass kills at least 100 million birds every year in the United States.
Is 30 feet better than 3 feet?
Guidance varies. Cornell recommends under 3 feet or on the glass. Others suggest 30 feet or more. The risky range is in between, where birds can build speed.
