Predicting Source Populations of Vagrants Using Breeding Population Data:A Case Study of the Lesser Black-Backed Gull (Larus fuscus)
Vagrancy is critical in facilitating range expansion and colonization through exploration and occupation of potentially suitable habitat. Uncovering origins of vagrants will help us better understand not only species-specific vagrant movements, but how the dynamics of a naturally growing population...

Vagrancy is critical in facilitating range expansion and colonization through exploration and occupation of potentially suitable habitat.
