Abstract

Effects of stress on waterfowl and grouse was studied in the USSR. Recreational activities in bird habitats disturb daily activity pattern and alter the behavior of birds. Disturbance causes additional predation pressures and losses of young to starvation; disrupted timing of breeding lowers female fertility and increases the number of inferior birds in the population.
