Description

Earlier offspring mortality before independence saves resources for kin, which should be more beneficial when food is short. Using 24 years of data on age-specific common tern (Sterna hirundo) chick mortality, best described by the Gompertz function, and estimates of energy consumption per age of mortality, we investigated how energy wasted on nonfledged chicks depends on brood size, hatching order, and annual abundance of herring (Clupea harengus), the main food source.
The dataset contains raw data on age-specific survival (in days) of common tern chicks (hatched in a colony in Wilhelmshaven, Germany) in relation to year (1992-2015), brood size, hatching order and standardized North sea herring abundance.
