Pelican Swallows A Pigeon

Parents ground-nesting species have another strange behavior: they sometimes drag older young around roughly by the head before feeding them. The young these species gather in "pods" or "crèches" up to 100 birds in which parents recognize and feed only their own fspring. By 6 to 8 weeks they wander around, occasionally swimming, and may practice communal feeding.
Young all species fledge 10 to 12 weeks after hatching. They may remain with their parents afterwards, but are now seldom or never fed. Overall breeding success is highly inconsistent.
Pairs are monogamous for a single season, but the pair bond extends only to the nesting area; mates are independent away from the nest.
