As a result of the study, it turned out that after the extermination of birds of prey, the number of game birds that they had previously destroyed was rapidly growing at first, but then rapidly decreasing. How can this regularity be explained?
To answer this question, the following points should be taken into account: an “uncontrolled” increase in the number of game birds leads to depletion of the food supply, weakening the resistance of bird organisms to diseases, the rapid spread of infection, degeneration, and a decrease in the fecundity and mass death of birds from diseases.
