How long is the incubation period for my backyard birds? How long until the young ones leave the nest?
The length of time varies from species to species. This webpage shows average clutch size, incubation and nestling period for a number of backyard birds. Note, these are averages, and actual numbers vary depending on location and time of year. You can also use our Common Nesting Birds page or All About Birds to determine the average incubation or nestling period of birds.Return to FAQ list
