Problems & Pests

Squirrels, window strikes, bully birds and sick birds.

Squirrels raiding feeders, birds hitting windows, aggressive visitors and signs of illness are familiar frustrations for backyard birders. This section helps you understand why these problems happen and what practical, humane steps can reduce them. It answers questions about baffles and feeder placement, window safety and what to do when birds look unwell.

For specific fixes, see keeping squirrels off your bird feeder and stopping window strikes. If you notice sick or lethargic birds, take feeders and baths down, clean them, wait a while before putting them back, and avoid handling wild birds yourself; contact your state wildlife agency or a licensed wildlife rehabilitator for guidance.
