A bird flew into a window: what to do next

Rescue guide · Last reviewed

Short answer

Put the bird in a ventilated cardboard box lined with cloth and leave it closed, dark and quiet for about an hour. Most window-strike birds are concussed and recover with nothing but rest. Do not offer food or water, keep cats away, and call a rescuer if it is bleeding, cannot stand, or is still dazed after an hour.

Birds cannot see glass. They see the reflected sky or the plants on the other side of a window and fly straight into it, often at full speed. A bird lying still underneath a window is usually stunned rather than dead, and a surprising number recover completely if left properly alone.

The mistake almost everyone makes is checking on it. Every time the box opens, the bird startles, and a concussed bird that keeps startling recovers more slowly.

How to help a bird that has hit a window

You will need: A cardboard box with air holes · A soft cloth or paper towel (no loose loops or terry towelling) · A quiet, dark room away from pets and children

  1. 1

    Get it away from cats immediately

    A stunned bird on the ground is defenceless, and this is where most window-strike birds are actually lost. Move it, or at minimum stand guard, before doing anything else.

  2. 2

    Put it in a closed, ventilated box

    Cover the bird with a cloth, lift it gently with both hands supporting the body, and place it in a cardboard box lined with soft fabric. Punch air holes from the inside out. Close the lid — the darkness is the treatment.

  3. 3

    Leave it completely alone for an hour

    Put the box somewhere quiet, indoors, at normal room temperature and out of direct sun. Do not open it to check, do not photograph it, and do not let children look in. Resisting the urge to peek is genuinely the most useful thing you can do.

  4. 4

    Test it outdoors after an hour

    Take the closed box outside, away from windows and with no cats around, set it down and open the lid while standing back. A recovered bird will simply fly off. If it flies strongly and straight, it is fine.

  5. 5

    If it does not fly, call a rescuer

    A bird still sitting in the box after an hour, or one that flutters and drops, has more than concussion — commonly internal bleeding, an eye injury or a fractured shoulder girdle. Close the lid and call a rescue helpline. Do not keep re-testing it.

Do

  • Keep the box closed. Darkness and stillness are what treat concussion in birds.
  • Release it outdoors near where it was found, and only if it flies strongly.
  • Check for a second bird — pairs and flocks often strike together.
  • Mark the glass afterwards with decals, screens or patterns to stop it happening again.

Do not

  • Do not give water, food, brandy, milk or any home remedy.
  • Do not keep opening the box to check on it.
  • Do not release a bird indoors, or anywhere a cat is present.
  • Do not release one that cannot stand, holds a wing oddly, or has blood at the beak or nostrils — that needs a vet.

Signs it is more than concussion

  • Blood at the beak, nostrils or ears.
  • One eye stays closed, or the two pupils are visibly different sizes.
  • A wing droops or the shoulders look asymmetrical.
  • It cannot stand, keeps toppling to one side, or holds its head tilted.
  • It is still dazed and unwilling to fly after an hour of quiet rest.

Stopping the next strike

Window collisions repeat at the same pane, because the reflection that fooled one bird fools the next. Breaking up the reflection on the outside surface is what works — anything applied inside the glass is largely invisible from outside.

  • Apply decals, tape strips or dot patterns spaced roughly 5-10 cm apart on the outside of the glass.
  • Fit an external screen, net or mesh a short distance in front of the pane.
  • Move indoor plants back from the window, since birds fly towards visible greenery.
  • Reposition bird feeders and water bowls either very close to the glass or well away from it, never at flight-speed distance.

Frequently asked

How long does it take a stunned bird to recover after hitting a window?

Most concussed birds recover within one to two hours of complete quiet in a closed, dark, ventilated box. Test it outdoors after an hour: a recovered bird flies off strongly as soon as the lid opens. If it will not fly, it needs a rescuer or a vet.

Should I give a stunned bird water or sugar water?

No. A concussed bird cannot swallow reliably and liquid can enter its lungs, which is frequently fatal. Rest in a dark box is the treatment, and no bird needs to eat or drink during that hour.

The bird looks dead but is warm. Is it?

Possibly not. Birds go very still and flat when deeply stunned or in shock, and can look dead while breathing shallowly. Place it in a closed ventilated box and give it an hour of complete quiet before concluding anything.

Can I release it from a balcony or window?

No. Release it at ground level in the open, well away from glass, with no cats nearby, and only if it flies off strongly under its own power. A bird dropped from height that cannot fly properly will be injured again on landing.
