Spatial consistency affects foraging effort in a benthic diving seabird, the Black‐faced Cormorant Open
For animals which exploit predictable food resources, greater foraging site fidelity has been hypothesized to lead to increased foraging efficiency. However, evidence for this in free‐ranging species is limited. In the present study, forag…
