Sex-specific foraging behaviour in a monomorphic seabird.
Sexual differences in the foraging behaviour of parents have been observed in a number of sexually sizedimorphic birds, particularly seabirds, and the usual inference has been that these sex-specific differences are mediated primarily by differences in body size. To test this explanation, we compared the foraging behaviour of parents in a monomorphic seabird species, the northern gannet Morus b...
متن کاملForaging niche segregation in Malaysian babblers (Family: Timaliidae)
Tropical rainforests are considered as hotspots for bird diversity, yet little is known about the system that upholds the coexistence of species. Differences in body size that are associated with foraging strategies and spatial distribution are believed to promote the coexistence of closely related species by reducing competition. However, the fact that many babbler species do not differ signif...
متن کاملOntogenetic changes in foraging behaviour and habitat use by the Oregon garter snake, Thamnophis atratus hydrophilus
Foraging behaviour, stream habitat use and food habits of a population of the aquatic, Oregon garter snake were studied in the field during the spring and summer of 1987 and 1988. Continuous records of behaviour and habitat use were obtained for each snake. Adults foraged more actively and in a wider variety of stream habitats than juveniles or neonates. Adults also fed on a wider variety of pr...
متن کاملThe Foods, Foraging Behaviour and Habitat Use of North Island Kokako in Puketi State Forest, Northland
The foraging behaviour, diet and habitat use of North Island kokako (Callaeas cinerea wilsoni) were studied in Puketi State Forest from October 1981 to August 1982. Kokako fed mainly from branches and twigs of canopy and upper-understorey plants. Although 68 different foods were eaten, only eight contributed more than 5% to the observed diet in any season. The diet consisted of fruit (44%), unk...
متن کاملMale harassment drives females to alter habitat use and leads to segregation of the sexes.
Sexual conflict is ubiquitous across taxa. It often results in male harassment of females for mating opportunities that are costly for females, in some cases reducing reproductive success and increasing mortality. One strategy that females may employ to avoid sexual harassment is to segregate spatially from males. In fact, we do find sexual segregation in habitat use in species that have high l...
