This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The loggerhead shrike (Lanius Iudovlcianus) is a strictly North American passerine experiencing population declines throughout its range. It is a former candidate for listing as Threatened or Endangered by the U.S. Fish and Wildlife Service. Shrikes are well-known for their behavior of impaling their prey on thorns and barbed wire. There are two subspecies that occur east of the Mississippi River, a resident subspecies and a rarer migrant subspecies. Shrikes breed throughout the southeastern United States, except for the Appalachian Mountain region and the eastern portions of North Carolina and Virginia. Loggerhead shrikes prefer open country, such as pastures with fence rows, old orchards, and mowed roadsides, where they feed on a variety of vertebrate and invertebrate prey. Longleaf pine savannas and open, mature stands of loblolly pine-shortleaf pine also provide suitable habitat for the shrike in the Southeast. Shrikes have been documented and are locally common on several military installations in the Southeast. This report is one of a series of 'Species Profiles' being developed for threatened, endangered, and sensitive species inhabiting southeastern United States plant communities. The work is being conducted as part of the Department of Defense (DoD) Strategic Environmental Research and Development Program (SERDP). The report is designed to supplement information provided in plant community management reports for major United States plant communities found on military installations. Information provided on the loggerhead shrike includes status, life history and ecology, habitat requirements, impacts and cause of decline, management and protection, and inventory and monitoring.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to summarize the methods, conceptual issues and results of studies using the interpretation of feather growth rates as an index of nutritional condition in birds. The author has coined the term ptilochronology (literally, 'the study of feather time') to describe this technique, which relies on the fact that as a feather grows it produces visible growth bars. Both the technique and its conceptual foundations have been applied worldwide to numerous studies ofavian evolution, ecology, and conservation biology. The author reviews this work, chronicles the various criticisms that have been made, and describes how these have influenced the development of ptilochronology. He goes on to suggest experimental methodologies and analytical techniques to safeguardagainst invalid results. A final chapter summarises this new technique's contribution to avian biology, and suggests potential applications and a future research agenda. An appendix details specific measurements and describes the methodology associated with ptilochronology.Ptilochronology provides a practical resource as well as a conceptual understanding of how this technique can be used to address important questions in avian biology. It will be of relevance and use to professional avian biologists and ornithologists as well as to graduate students of avian behavioural ecology, evolution and conservation.

This book was released on 2006 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Loggerhead Shrikes (Lanius ludovicianus) have been declining in the United States since the 1960s, and in Kentucky they declined by 9.6% from 1980-2003. Suggested causes for their decline include eggshell thinning due to DDT exposure, loss of suitable habitat, low reproductive success, and competition with exotic species in parts of their range. None of these, however, have provided a definitive reason for the decline. The objective of my study was to examine the reproductive success of Loggerhead Shrikes in central Kentucky and to determine the possible effect of habitat availability and suitability on the abundance and reproductive success of Loggerhead Shrikes. Shrikes were studied from 15 March-30 September 2005 in Madison and Garrard counties, Kentucky, and breeding adults were fitted with radio transmitters so that I could measure their territory sizes. Additionally, I measured nest-level and territory-level habitat characteristics and I also monitored active nests to assess reproductive success. Lastly, hunting behaviors and habitats were recorded. Mean territory (N = 12) size was 9.0 ha and nests (N = 18) were most often located in Eastern red cedar, Osage orange, and multiflora rose. Nest-level habitat characteristics of used and unused sites differed, with the percentage of bare ground and vegetation height within 10 m of nests being the best discriminating variables between such sites. there were no differences between the habitat characteristics of successful and unsuccessful nests, or between used and unused territories. Shrikes most often caught prey that were identified as arthopods and usually hunted from linear man-made structures such as fencelines and utility wires. Reproductive success was low in my study, with 50% of nests failing and only 42.8% of eggs resulting in fledglings. The availability of suitable breeding habitat does not appear to be a limiting factor in central Kentucky Loggerhead Shrikes populations, though low reproductive success prior to fledging may be a limiting factor. Low reproductive success of Loggerhead Shrikes in central Kentucky may be a result of recent increases in local avian and mammalian predators. Loggerhead Shrike management should focus on ensuring that nesting habitat is available in habitats that are not foraging corridors for mammalian predators (i.e., non-linear habitats), and Shrikes may also benefit from a hand-rearing program that increases the yearly production of young.

Available in PDF, EPUB and Kindle. Book excerpt: Focusing on families and their shared traits makes bird identification easier than ever. This guide takes readers beyond merely identifying birds to understanding them. Many birders can tell the difference between a White-eyed and Bell's Vireo but cannot begin to describe a vireo and what distinguishes members of this family from warblers or flycatchers. The "species by species" approach makes it difficult to appreciate birds for what they are: members of well-organized groupings united by common traits. Putting the focus on families, and their shared characteristics, makes bird identification easier and more meaningful. More than 150 color photos illustrate the 81 bird families of the United States and Canada.
