Purple martins typically lay three to six eggs, and the young nestlings usually fledge at around a month in age. On the East Coast of the United States, this species relies heavily on man-made bird houses, and it’s fine to check on the eggs and hatchlings—nest checks can help birdhouse “landlords” prevent problems.
