Spatial consistency affects foraging effort in a benthic diving seabird, the Black‐faced Cormorant

open access: yesIbis, Volume 167, Issue 2, Page 468-480, April 2025.
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, foraging site fidelity, the factors influencing it and its effect on foraging effort were investigated in the Black ...
