What to Do When a Bird Hits a Window

In the bridge post for this cluster we told a short story about a Pine Grosbeak. It hit a big window one cold morning, sat stunned in the snow beneath the glass, and for a few long minutes we were sure it was gone. We kept our distance, gave it quiet, and waited. After a while it shook itself, found its feet, and lifted off into the spruce. That bird recovered because of what we did not do as much as what we did. This guide is how to give the next bird that same chance.

Finding a bird down at your window is upsetting, and the instinct to scoop it up and help is a kind one. But the best first aid for a stunned bird is mostly calm, restraint, and knowing the few moments when expert help is essential. For why this happens in the first place see why birds hit windows, and for stopping it happening again see how to stop birds from hitting windows. This post is about the bird in front of you right now.

First, watch and wait

Before you touch anything, give the bird a little space and simply watch for a few minutes. A great many window casualties are only stunned, dazed by the impact the way we would be, and they come round on their own and fly off within minutes if left in peace. Handling a bird that does not need handling only adds stress, which can do its own harm, so the gentlest and often most effective thing you can do at first is nothing.

There is one exception. If the bird is lying somewhere exposed, on a sidewalk, a driveway, or anywhere a cat, a dog, or traffic could reach it, the risk of a predator or a second injury outweighs the value of leaving it. In that case move it a short distance to a sheltered, quiet spot nearby, or have someone keep watch over it, while it recovers.

If it does not recover, contain it gently

If several minutes pass and the bird still cannot fly, it needs a safe, dark place to rest. Prepare a simple container first, a paper bag or an unlined shoebox with a few air holes punched in it, with a paper towel or a smooth cloth in the bottom for grip. Avoid terry cloth towels, because the loops can catch a bird's feet and claws. A plain paper bag works beautifully and is what many rehabilitators recommend.

To pick the bird up, approach calmly from behind and cover it gently with both hands, keeping its wings folded against its body. Small birds are astonishingly fragile, so never squeeze. The grip should feel as light as holding a cotton ball. Place the bird upright in the bag or box, withdraw your hands without letting it escape, and close the container.

Then set it somewhere dark, quiet, and at normal room temperature, well away from pets, children, noise, direct sun, and the draft of a heating or cooling vent. Do not offer food or water. This is important, because it is genuinely easy to choke or drown a dazed bird, and a recovering bird does not need either. The darkness and the quiet are the whole treatment. What the bird needs is calm and time, nothing more.

Releasing the bird

Leave the box completely undisturbed for about an hour, and resist the strong temptation to keep peeking, since every check sets the recovery back. Some birds need only ten or fifteen minutes, others a few hours. After an hour or so, carry the closed box outside, well away from windows, set it down, and open the lid. A bird that has recovered will usually fly off smartly on its own. Do not lift it out and toss it into the air to make it fly. If it is not quite ready, close the box gently and give it a little longer.

When to call a wildlife rehabilitator

Sometimes rest is not enough, and this is the part that matters most. Call a licensed wildlife rehabilitator if you see any clear injury, such as bleeding, a drooping or twisted wing, a head tilt, or an eye that looks damaged, or if the bird simply cannot fly after a couple of hours of quiet. Trust your doubt here. Window strikes very often cause injuries you cannot see from the outside, concussion and internal bleeding among them, so a bird that looks merely stunned can be more hurt than it appears. A rehabilitator has the training, the medication, and the legal permits to give it a real chance that home care cannot.

To find one, search for a wildlife rehabilitator or wildlife rescue in your area, contact your local or regional wildlife agency, or ask a veterinary clinic, which will usually know who takes wildlife nearby. Many regions have a dedicated rehabilitator directory or helpline. It is worth finding the number before you ever need it, so it is on hand in the moment.

The emergencies: cats, raptors, and large birds

A few situations are not wait and see at all. They need a rehabilitator straight away.

The most urgent is a bird that a cat has caught, whether at your window or anywhere else. Cat saliva carries bacteria that cause a rapidly fatal blood infection in birds, and even a tiny puncture or scratch you can barely see is enough. A cat caught bird needs to reach a rehabilitator and get antibiotics quickly, ideally within a few hours, even if it looks completely unharmed. Do not wait to see how it does. If the cat is your own, the longer term fixes are in how to stop your cat from killing birds.

The other situations are about your own safety. If the casualty is a bird of prey, a hawk, an owl, a falcon, or an eagle, do not try to handle it. A stunned raptor that comes round in your hands can drive its talons through skin in an instant. The same caution applies to large birds like herons and gulls, which have long, sharp bills. For any of these, keep your distance, keep people and pets back, and call a rehabilitator or animal control to handle the rescue.

What not to do

A short list of the mistakes that do the most harm. Do not try to nurse the bird back to health yourself or keep it as it recovers over days. Beyond the fact that it rarely works, wild native birds are protected by law across North America and much of the world, and keeping one without a permit is illegal. Do not give food or water. Do not handle the bird more than the one careful pickup requires, and do not keep opening the box to check. And never use a container with loose strings or loops, or a loose weave towel, that a bird's feet can tangle in.

Give it that chance

Most of helping a stunned bird is getting out of its own way, a dark box, an hour of quiet, and the judgment to call an expert when something is wrong. That is what gave our Pine Grosbeak its morning flight back into the spruce. And once the immediate drama has passed, the kindest thing you can do for every bird that comes after is to make sure it does not happen again, which is exactly what how to stop birds from hitting windows is for. Seen against everything in the causes of bird deaths in North America, one rescued bird and one treated window are small things, but together they add up.
