Large- and Small-Scale Climate Influences Spring Migration Departure Probability of American White Pelicans
Endogenous (e.g., age and sex) and exogenous (e.g., climate and resource availability) factors influence avian migration phenology. However, little is known regarding the migration ecology of birds at the non-breeding grounds, including the American white pelican ( Pelecanus erythrorhynchos ). We us...
