Bird Hazards and Flight Over National Refuges, Parks, and Forests

−4−5. Pilot Advisories on Bird and Other

Wildlife Hazards

Many airports advise pilots of other wildlife hazards
caused by large animals on the runway through the
Chart Supplement U.S. and the NOTAM system.
Collisions of landing and departing aircraft and
animals on the runway are increasing and are not
limited to rural airports. These accidents have also
occurred at several major airports. Pilots should
exercise extreme caution when warned of the
presence of wildlife on and in the vicinity of airports.
If you observe deer or other large animals in close
proximity to movement areas, advise the FSS, tower,
or airport management.
