Population density of the Réunion Grey White-eye Zosterops borbonicus within the summit ecosystems of Réunion, Mascarene Islands
Assessing population density is crucial for studying the ecology and evolutionary biology of species as well as for conservation purposes. Here we used point count methods to infer population density in a single-island endemic passerine bird, the Réunion Grey White-eye Zosterops borbonicus, that dis...
