Community Ecology of Neotropical Kingfishers (UC Publications in Zoology)

To determine the mechanisms for species-spacing in a group of closely related bird species—namely, five species of Neotropical Kingfishers—the author studied their feeding behavior and diet at three sites, two in Bolivia and one in Colombia. He found that changes in number of coexisting species were correlated with changes in abundance and size distribution of their prey, surface-dwelling fishes.
