Download or read book New World Warblers written by Jon Curson and published by A&C Black. This book was released on 2010-06-30 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the same format as other book in the series, this guide to North American wood warblers, the parulinae, looks at their distribution throughout the USA and into Central and South America. New World warblers are one of the most colourful, popular and enigmatic groups of North American birds. This is the first time comprehensive guide to the identification, ageing and sexing of all 116 species. Thirty-six colour plates show the major age, sex and racial variations for all species (many of which have never been fully illustrated before). They are accompanied by colour distribution maps and black-and-white drawings. Jon Curson's up-to-the-minute text is based on over ten years' field research in North, South and Central America coupled with meticulous museum work by both author and artists. The book contains a full text for each species, including wing-formulae drawings. Some of the species covered find their way to the UK and Europe. New World Warblers represents a significant step forward in our knowledge of one of the most beautiful and conspicuous groups of North American birds.

Available in PDF, EPUB and Kindle. Book excerpt: “A wonderful book that highlights the globally unique and important boreal forest ecoregion from an avian perspective, with fresh twists. Your ideas about where those migrant and wintering birds in your backyards have come from will be forever changed after you read this.”--Gordon Orians, Professor Emeritus of Biology, University of Washington “One of the planet's most amazing spectacles is the seasonal ebb and flow of migrants from the boreal forests to warmer winter quarters, with stopovers in our neighborhoods in between. This book tells you how connected the world is and what's at risk if we damage any part of it.”--Stuart Pimm, Doris Duke Professor of Conservation Ecology, Duke University, winner of the 2006 Dr. A. H. Heineken Prize “This diverse set of contributions about birds that nest in and migrate to and from North America's boreal forest demonstrates the remarkable interconnectedness of ecosystems across the hemispheres and the incredible responsibility we face to protect them.”--Bridget Stutchbury, York University, author of Silence of the Songbirds and The Private Lives of Birds “The fact that billions of birds breed in North America’s boreal forest is amazing enough, but this assemblage is even more remarkable when understood as playing completely different, major ecological roles across the temperate and tropical Americas during the northern winter. This book definitely will broaden your thinking about ecological connections across the hemisphere and the global-scale phenomenon that crosses our skies twice each year.”--John W. Fitzpatrick, Louis Agassiz Fuertes Director, Cornell Lab of Ornithology

This book was released on 2010-09-21 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hugh P. Possingham Landscape-scale conservation planning is coming of age. In the last couple of decades, conservation practitioners, working at all levels of governance and all spatial scales, have embraced the CARE principles of conservation planning – Comprehensiveness, Adequacy, Representativeness, and Efficiency. Hundreds of papers have been written on this theme, and several different kinds of software program have been developed and used around the world, making conservation planning based on these principles global in its reach and influence. Does this mean that all the science of conservation planning is over – that the discovery phase has been replaced by an engineering phase as we move from defining the rules to implementing them in the landscape? This book and the continuing growth in the literature suggest that the answer to this question is most definitely ‘no. ’ All of applied conservation can be wrapped up into a single sentence: what should be done (the action), in what place, at what time, using what mechanism, and for what outcome (the objective). It all seems pretty simple – what, where, when, how and why. However stating a problem does not mean it is easy to solve.

Download or read book Cerulean Warbler Status Assessment written by Paul B. Hamel and published by Createspace Independent Pub. This book was released on 2012-08-16 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cerulean warbler, Dendroica cerulea (Wilson), is a wood warbler in the Subfamily Parulinae of the Family Emberizidae, Order Passeriformes. No controversial or unsettled issues exist in the taxonomy of this bird. The numbers of cerulean warblers are declining at rates comparable to the most precipitous rates documented among North American birds by the cooperative Breeding Bird Survey. Recent evidence suggests that events on breeding, stopover, and wintering grounds are implicated in this decline. However, no detailed life history study of the species exists. This status assessment is an attempt to assemble what is known of the species into a form that will enable biologists in the U.S. Fish and Wildlife Service to make a decision on whether or not to propose listing of the species under the Endangered Species Act. The report will also help the Service and others establish priorities for monitoring; research; and habitat protection, restoration, and management that will conserve this species. Cerulean warbler is a small, neotropical migratory bird that weighs approximately 8-10 grams, and has relatively long, pointed wings and a short tail. All plumages have two white wing bars and white tail spots. Males have streaked backs in all plumages; females do not. Males in breeding plumage are blue above, white below, with a blueblack neck ring. Females in breeding plumage are bluish green above, white below washed with yellow, with a white or yellowish line over the eye. Young birds are similar to the adult females but greener. Cerulean warblers feed primarily on insects throughout the year. Open-cup nests are placed in the canopy of forest trees where the birds raise usually a single brood. Clutch size is usually 3-4 eggs. Adult and juvenile mortality rates are unknown. The longevity record is at least 6 years. Only 1 of 1399 banded individuals has been encountered later away from the original capture locality. Conventional wisdom about habitat for cerulean warblers is that the birds breed in large tracts of deciduous forest having large trees and an open understory. These tracts may be in upland or bottomland situations. Migratory and winter season habitats are poorly known. Cerulean warblers breed in eastern North America primarily in the Ohio and Mississippi River valleys. The range generally extends from the eastern Great Plains, north to Minnesota; east to Massachusetts; and south to North Carolina and Louisiana. During migration the birds pass through the southern U.S., across the Gulf of Mexico to the highlands of Central America, and on to South America. They winter in the lower elevations of the subtropical zone of the eastern slope of the Andes and other mountains in northern South America. Historical data on the occurrence and abundance of the species are sparse and do not permit estimation of total numbers. However, it is clear that this species was a conspicuous and abundant bird throughout the Ohio and Mississippi River valleys in the past century. Currently the birds are much less numerous in areas where formerly they were abundant. The North American Breeding Bird Survey suggests that, during the past 30 years, the population has declined at an average annual rate of approximately 4%. Summaries of the Breeding Bird Survey, Breeding Bird Census, Breeding Bird Atlas, conservation status, and other information pertinent to individual nations, states, and provinces are presented for each political division within the range of the species. Current numbers and distribution of the species are such that an adequate summary of occurrence by land ownership categories cannot be prepared, other than to state that the birds are found on public lands, industrial forest lands, and other private lands. One study found the birds more frequently on public than on other land ownerships.

Download or read book Golden winged Warbler Ecology Conservation and Habitat Management written by Henry M. Streby and published by CRC Press. This book was released on 2016-10-26 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Golden-winged Warblers (Vermivora chrysoptera) are migratory songbirds that breed in temperate North America, primarily in the Great Lakes region with remnant populations throughout the Appalachian Mountains, and winter in Central and northern South America. Their breeding range has contracted dramatically in the Appalachian Mountains and many populations have dramatically declined, likely due to habitat loss, competition and interbreeding with Blue-winged Warblers (Vermivora pinus), andglobal climate change.. As a result of population declines in much of the eastern portion of their breeding range, Golden-winged Warblers are listed as endangered or threatened in 10 U.S. states and in Canada and have been petitioned for protection under the U.S. Endangered Species Act. Published in collaboration with and on behalf of The American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series compiles extensive, current research on Golden-winged Warblers and summarizes what is known and identifies many remaining unknowns, providing a wealth of peer-reviewed science on which future research and listing decisions can be based.

We are sure that it is disappearingfast, yet at present we cannot even measure progress (orotherwise) towards the 2010 target set by world leaders forslowing this loss. This BirdLife assessment examines what the bestknown group of living things, birds, can tell us about the stateof biodiversity, the pressures upon it and the solutions that arebeing, or should be, put in place. It is a synthesis of currentknowledge and provides a benchmark against which we can assess ourefforts to conserve biodiversity in the future.`Anexciting testimony to BirdLife's Intent and capacity to influencepolicy at the highest levels... gives a clear overview of howindividual observations contribute to the bigger picture...auseful digest of contemporary conservation science presented in aless technical way.
