How often do birds lay eggs in a year?

The frequency with which birds lay eggs in a year can vary significantly depending on the species. Some birds, such as pigeons and mourning doves, are capable of laying multiple clutches of eggs throughout the year. These multi-brooded species can lay anywhere from 2 to 12 clutches per year, each consisting of one to two eggs. On the other hand, some bird species, including many birds of prey and seabirds, lay only a single clutch of eggs per year. These single-brooded species lay a larger number of eggs in their single clutch, ranging from one to several eggs depending on the species. The size of their clutches, the number of eggs, and the duration of the breeding season also greatly differ among species. Therefore, the actual number of eggs laid by different bird species in a year varies widely.
