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.
