Editor's Choice: Experimental assessment of South African vultures competing for food resources


Recommended Posts

Mark E. Hauber, Editor-in-Chief of The Auk: Ornithological Advances:

"Experimentation is at the heart of robust ecological research, and it is especially so to test predictions of foraging theories. Ornithologists have often pioneered sophisticated experiments in the lab and large-scale manipulations in the field, and Corinne Kendall's new research on vultures used provisioned carcasses to assess the interaction between daytime and species identity in competing scavengers. The results show that even vultures can have too much of a good thing; daily satiation by dominant species generates a time window during which a subordinate species is able to feed, but this is still not enough to compensate for being excluded from the carcasses earlier during the day, and so overall competition for carrion remains intense on a daily basis."
