Identification of nest predators: a sampling perspective
Videotaping is currently recognized as the most reliable method of predator identification at active bird nests but it is relatively expensive and labour intensive. While the number of published studies has increased over the past 10 years, the mean sample size is not increasing. Thirty-one case studies (n 5 events) reported 6 70 (median 22) predation events by 2 14 (6) species of predators. Th...
متن کاملIdentification of Sprague's Pipit Nest Predators
Nest predation is the primary factor influencing grassland songbird reproductive success. Understanding factors driving spatial and temporal variation in nest survival requires that we identify the primary nest predators and factors influencing predator abundance and behavior. Predation events are rarely witnessed, and the identification of nest predators is inferred, often incorrectly, from ne...
متن کاملFlight Behaviour of Passerines on Nocturnal Migration
Many passerines migrate during the night and at high altitudes, making their migration difficult to observe. By using tracking radars we have been able to make exact observations of the flight behaviour of passerines on nocturnal migration, which has enabled us to test several hypotheses about adaptive values and constraints regarding migratory behaviour in different ecological contexts. We hav...
متن کاملMicrohabitat structure and avian nest predation risk in an open Argentinean woodland: an experimental study
We studied the effect of the general structure of the nest plant, especially the presence of thorns, and the structural homogeneity of the nest patch, on the vulnerability of nests to predation, using natural and artificial nests. Artificial nests placed in non-thorny plants had a significantly lower predation rate and higher daily survival rate than those in thorny plants. The addition of a ‘t...
متن کاملDo artificial nests simulate nest success of greater sage-grouse?
Artificial nests have been used to study factors affecting nest success because researchers can manipulate them more than natural bird nests. Many researchers have questioned the validity of generalizing the results from artificial nests onto naturally occurring nests. Other studies have assessed the validity of artificial nest studies by simultaneously comparing overall depredation or daily su...
