Book excerpt: From 1988 to 2002 we studied the breeding ecology of Florida Scrub-Jays (Aphelocoma coerulescens) on John F. Kennedy Space Center/Merritt Island National Wildlife Refuge. We examined phenology, clutch size, hatching failure rates, fledgling production, nest success, predation rates, sources egg and nestling mortality, and the effects of helpers on these measures. Nesting phenology was similar among sites. Mean clutch size at Titan was significantly larger than at HC or T4. Pairs with helpers did not produce larger clutches than pairs without helpers. Fledgling production at T4 was significantly greater than at HC and similar to Titan. Pairs with helpers at HC produced significantly more fledglings than pairs without helpers; helpers did not influence fledgling production at the other sites. Nest success at HC and Titan was low, 19% and 32% respectively. Nest success at T4 was 48% and was significantly greater than at HC. Average predation rates at all sites increased with season progression. Predation rates at all sight rose sharply by early June. The main cause of nest failure at all sites was predation, 93%.

Book Synopsis Bird Population Studies by : Christopher M. Perrins
Download or read book Bird Population Studies written by Christopher M. Perrins and published by Oxford University Press, USA. This book was released on 1991 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are more than one thousand species of threatened birds in the world, while many others are valued for sport and some are serious pests. This volume reviews our current understanding of avian population dynamics and explores ways in which population studies can contribute to effective conservation and management. Estimation of demographic parameters, the role of mathematical modelling, and the special problems of island populations and seabird populations are discussed. The emphasis throughout is on how bird populations are regulated under various constraints and conditions, including the impact of environmental changes.
Book Synopsis The Florida Scrub Jay (MPB-20), Volume 20 by : Glen Everett Woolfenden
Download or read book The Florida Scrub Jay (MPB-20), Volume 20 written by Glen Everett Woolfenden and published by Princeton University Press. This book was released on 2020-03-31 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Florida Scrub Jays are an excellent example of a cooperative-breeding species, in which adult birds often help raise offspring not their own. For more than a decade Glen E. Woolfenden and John W. Fitzpatrick studied a marked population of these birds in an attempt to establish a demographic base for understanding the phenomenon of "helping at the nest." By studying both population biology and behavior, the authors found that habitat restraints, rather than kin selection, are the main source of the behavior of Florida Scrub Jays: the goal of increasing the number of close relatives other than descendants in future generations is of relatively minor importance in their cooperative-breeding behavior. The Florida Scrub Jay lives only in the Florida oak scrub. All acceptable habitat is constantly filled with breeders. Each year about half of the pairs are assisted by one to several nonbreeding helpers. This book provides extensive data on fecundity, survivorship, relatedness, and dispersal to establish the demographic milieu and to address questions arising out of observed helping behavior--whom, how, when, and why the helpers help.
Book Synopsis Florida Scrub-Jay by : Mark Jerome Walters
Download or read book Florida Scrub-Jay written by Mark Jerome Walters and published by University Press of Florida. This book was released on 2021-02-08 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Florida Historical Society Stetson Kennedy Award A portrait of a species on the brink The only bird species that lives exclusively in Florida, the Florida scrub-jay was once common across the peninsula. But as development over the last 100 years reduced the habitat on which the bird depends from 39 counties to three, the species became endangered. With a writer’s eye and an explorer’s spirit, Mark Walters travels the state to report on the natural history and current predicament of Florida’s flagship bird. Tracing the millions of years of evolution and migration that led to the development of songbirds and this unique species of jay, Walters describes the Florida bird’s long, graceful tail, its hues that blend from one to the next, and its notoriously friendly manner. He then focuses on the massive land-reclamation and canal-building projects of the twentieth century that ate away at the ancient oak scrub heartlands where the bird was abundant, reducing its population by 90 percent. Walters also investigates conservation efforts taking place today. On a series of field excursions, he introduces the people who are leading the charge to save the bird from extinction—those who gather for annual counts of the species in fragmented and overlooked areas of scrub; those who relocate populations of scrub-jays out of harm’s way; those who survey and purchase land to create wildlife refuges; and those who advocate for the prescribed fires that keep scrub ecosystems inhabitable for the species. A loving portrayal of a very special bird, Florida Scrub-Jay is also a thoughtful reflection on the ethical and emotional weight of protecting a species in an age of catastrophe. Now is the time to act, says Walters, or we will lose the scrub-jay forever.
Download or read book Conservation by Proxy written by Tim Caro and published by Island Press. This book was released on 2010-06-23 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.

Book excerpt: "You are a rare bird, easy to see but invisible just the same." That thought is close at hand in Sparrow Envy: Field Guide to Birds and Lesser Beasts, as renowned naturalist and writer J. Drew Lanham explores his obsession with birds and all things wild in a mixture of poetry and prose. He questions vital assumptions taken for granted by so many birdwatchers: can birding be an escape if the birder is not in a safe place? Who is watching him as he watches birds? With a refreshing balance of reverence and candor, Lanham paints a unique portrait of the natural world: listening to cicadas, tracking sandpipers, towhees, wrens, and cataloging fellow birdwatchers at a conference where he is one of two black birders. The resulting insights are as honest as they are illuminating.
