United States Fish and Wildlife Service Alaska Maritime National Wildlife Refuge20250314130050tabular digital dataSurvival estimates are needed for population models, and have been shown to be a particularly sensitive parameter in long-lived seabirds. Alaska Maritime National Wildlife Refuges estimates and detect trends in average overwinter survival rates for adult least auklets (LEAU) on St. George Island. Annual survival of least auklets apparently covaries with broad-scale climate patterns (e.g., Jones et al. 2002) and is intended to provide insight into causes of population change.Banding history table details the combination of metal and auxiliary bands that individuals in the banded population of LEAU on St. George Island wore, and when those bands would have been resightable.The banding history table relates to the organisms table on the organismID field, with potentially multiple band history records per organism record.Track the changes to metal and aux bands on birds through the duration of the survival study.
