Protect Birds From Open Pipes
Exposed vertical pipes with open tops pose a tremendous hazard to birds and other
wildlife. They are particularly hazardous for birds that either fall into these openings, or
enter looking for nesting space. Once inside, birds are unable to open their wings to fly
out, and the smooth sides make it impossible to climb out. Inevitably, the birds suffer a
miserable, unnecessary death from starvation and exposure.

Open pipes are a threat to all birds

Open pipes kill birds indiscriminately. Both common birds and protected species have
been found among the layers of dead birds in open pipes. And the destruction can occur
in pipes from one to 10 inches wide.

Audubon California staff recently pulled down a 20-foot-tall ventilation pipe from an
abandoned irrigation system and discovered a seven-foot-long black mass composed
entirely of decomposed carcasses of hundreds of dead birds and animals including
kestrels, flickers, bluebirds, and fence lizards. The date etched into the concrete at the
base of the pipe showed that it had been in place for more than 50 years.

Open vertical pipes occur in more places than you might think, including:

  • Sign posts
  • Fences
  • Survey markers
  • Buildings
  • Irrigation systems
  • Unused chimneys

How you can help on your property

  • Look around and identify all the open top vertical pipes on your property.
    Cap, close, remove or screen all of them.
  • Put screens over sapling protector tubes, or leave openings at the bottom for birds
    and wildlife to escape.
  • When you visit other properties – public or private – share what you know about
    the dangers of open pipes.
