Situations where bird control is important:
(1) near airports to avoid bird strikes
(2) around bridges or buildings that may be damaged by bird droppings
(3) high bird density
(4) infection control
Basic strategies:
(1) eliminate roosting and nesting sites
(2) eliminate food
(3) harass (startle or drive away)
(4) capture and release
(5) avicide (kill)
Elimination of roosting or nesting sites may involve:
(1) removing structures used by birds
(2) placing nets or mechanical barriers to landing
(3) physically removing nests
Eliminating food:
(1) removal of natural food sources
(2) control of human food scraps
Biological ways of driving away birds:
(1) dogs
(2) falcons
Physical ways of driving away birds:
(1) loud sounds
(2) lights
(3) scarecrow
(4) radio-controlled airplane
Capture and release involves capturing a bird in a trap then releasing the animal at a distant location.
Avicidal is the method of last resort and sure to upset some people.
(1) poison (which may be a hazard to other wildlife)
(2) shooting
(3) electrocution
One barrier is cost. Any deterrent strategy requires implementation and maintenance, which can be significant for a large structure or area. The more personnel time required (as in capture and release) the greater the cost.
