The osprey young are still using the nest as home base and will continue to do so until they migrate in September. The female adult usually migrates first, while the male adult remains behind to help the young with meals. The male will migrate about the same time as the young, which is a few weeks after the mother, depending on the chicks' development.
All but the southernmost breeding populations in North America are migratory, vacating their breeding grounds in late summer for rain-forest rivers and fish-rich seacoasts and lakes of Central and South America.
