Question

how birds lay eggs.

Answer 1

Throughout the year, most birds use day length to tell what season it is. When the number of hours of daylight exceeds a certain critical level, physiological changes are triggered in birds which prepare them to breed. Most birds, especially those in temperate regions, also time their breeding activities so that they will be feeding their nestlings when food is most abundant. However, well before nestlings arrive, birds need to select a breeding territory. Non-migratory species may either maintain a territory throughout the winter or establish a new one in the spring. Migratory birds begin looking for and defending a territory as soon as they arrive in the spring. Good territories provide potential nest sites, reliable food sources, and protection from predators.
