Summary:
The author examined two adjacent populations of endangered Hawaii Akepa (Loxops coccineus coccineus) that differed in density by a ratio of 3:1. A comparison of demographic characteristics between these two populations suggested that differences in environmental carrying capacity, such as in food or nest-site availability, maintain current patterns of density. This study points to nest-site availability as a strong determinant of population size in the remaining habitat of the Hawaii Akepa. The mixed-species flocking phenomenon in a Hawaiian rainforest was characterized, which showed that the abundance of Akepa within flocks was significantly greater, relative to their density, at the low density site.
