Book excerpt: The Florida Scrub-Jay (Aphelocoma coerulescens) is an indicator of ecosystem integrity of Florida scrub, an endangered ecosystem that requires frequent fire. One of the largest populations of this federally threatened species occurs on John F. Kennedy Space Center/Merritt Island National Wildlife Refuge. Population trends were predicted using population modeling and field data on reproduction and survival of Florida Scrub-Jays collected from 1988 - 1995. Analyses of historical photography indicated that habitat suitability has been declining for 30 years. Field data and computer simulations suggested that the population declined by at least 40% and will decline by another 40% in 1 0 years, if habitat management is not greatly intensified. Data and computer simulations suggest that habitat suitability cannot deviate greatly from optimal for the jay population to persist. Landscape trajectories of vegetation structure, responsible for declining habitat suitability, are associated with the disruption of natural fire regimes. Prescribed fire alone can not reverse the trajectories. A recovery strategy was developed, based on studies of Florida Scrub-Jays and scrub vegetation. A reserve design was formulated based on conservation science principles for scrub ecosystems. The strategy emphasizes frequent fire to restore habitat, but includes mechanical tree cutting for severely degraded areas. Pine thinning across large areas can produce rapid increases in habitat quality. Site-specific strategies will need to be developed, monitored, and modified to achieve conditions suitable for population persistence. Breininger, D. R. and Larson, V.

This book was released on 2013-06 with total page 30 pages. Available in PDF, EPUB and Kindle. 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%.

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.

This book was released on 2018-11-07 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Florida Scrub Jay is endemic to Florida. The John F. Kennedy Space Center (KSC) provides habitat for one of the three largest populations of the Florida Scrub Jay. This threatened bird occupies scrub, slash pine flatwoods, disturbed scrub, and coastal strand on KSC. Densities of Florida Scrub Jays were shown to vary with habitat characteristics but not necessarily with vegetation type. Relationships between Florida Scrub Jay densities and habitat characteristics were used to develop a habitat model to provide a tool to compare alternative sites for new facilities and to quantify environmental impacts. This model is being tested using long term demographic studies of colorbanded Florida Scrub Jays. Optimal habitat predicted by the model has greater than or equal to 50 percent of the shrub canopy comprised of scrub oaks, 20-50 percent open space or scrub oak vegetation within 100 m of a ruderal edge, less than or equal to 15 percent pine canopy cover, a shrub height of 120-170 cm, and is greater than or equal to 100 m from a forest. This document reviews life history, social behavior, food, foraging habitat, cover requirements, characteristics of habitat on KSC, and habitat preferences of the Florida Scrub Jay. Construction of the model and its limitations are discussed. Breininger, David R. Unspecified Center...

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.
