Breeding synchrony in birds, large clusters of individuals that are in the same breeding stage at the same time, is a well-known phenomenon. Individuals birds are expected to adapt their breeding schedules to changing environmental conditions: they all should aim to raise their chicks when they have the highest chance of survival. This way birds living in the same place and having the same environmental conditions will develop the same breeding schedules. But sharing comparable environmental conditions is not the only reason why birds might develop equal breeding times. Recent studies have shown that birds adapt their breeding schedules to the breeding schedules of close living neighbors. And although this can create breeding times which deviate from the optimal response to environmental change in an individual birds’ perspective, it still may enhance their fitness. In this paper, I will discuss how breeding synchrony may enhance or reduce fitness in colonial birds and what selection pressures may have led to breeding synchrony.
