Book Description
The characteristics of shrike nest sites, territories, and hunting perches were analyzed and compared to those of apparently suitable, but unoccupied sites and areas and unused perches. Multivariate analysis revealed no significant differences between used and unused nest sites, territories, and perches (P > 0.19), suggesting that availability of suitable breeding and foraging habitat is likely not contributing to the decline of Loggerhead Shrike populations in central Kentucky. Additional information is needed concerning adult and fledgling mortality, prey abundance, and winter habitat use to provide further insight into factors contributing to the decline in populations of Loggerhead Shrikes.

Book Description
I observed 1372 hunting attempts by Loggerhead shrikes, with trees (36.9%) and fences (34.9%) the most commonly used perches and arthropods (65.3%) and other invertebrates (23.3%) the most common prey. Vegetation analysis revealed the characteristics of used and apparently unused perches were significantly different (P

Book Description
Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.

Book Description
Many animal species live and breed in colonies. Although biologists have documented numerous costs and benefits of group living, such as increased competition for limited resources and more pairs of eyes to watch for predators, they often still do not agree on why coloniality evolved in the first place. Drawing on their twelve-year study of a population of cliff swallows in Nebraska, the Browns investigate twenty-six social and ecological costs and benefits of coloniality, many never before addressed in a systematic way for any species. They explore how these costs and benefits are reflected in reproductive success and survivorship, and speculate on the evolution of cliff swallow coloniality. This work, the most comprehensive and detailed study of vertebrate coloniality to date, will be of interest to all who study social animals, including behavioral ecologists, population biologists, ornithologists, and parasitologists. Its focus on the evolution of coloniality will also appeal to evolutionary biologists and to psychologists studying decision making in animals.
