Migration Info This is one of the latest U.S. arrivals in spring, and is also one of the first to leave; some individuals spend less than a month in the breeding territory. This is possible because of the extremely rapid development of the young: The entire breeding cycle, from egg laying to fledging of young, may be completed in as little as 17 days. Eastern populations reach the New England states in late May or early June, while western birds at the same latitudes may arrive two weeks later. This species has been nearly extirpated in California due to loss of riparian breeding habitat.
