--Queen's University, 2002. 549-562. in Ecology and conservation of neotropical migrant landbirds. Breeding primarily occurs on ridge tops and steep slopes within the species’ Appalachian breeding range. var imgAlt = dom_i.query(this).attr("alt") == undefined ? '' } Results from presence and absence modeling were inconclusive as no habitat-related differences were identified between occupied and unoccupied locations within the study area. 2000b. %PDF-1.4 %���� 0000004268 00000 n 2000. Cerulean warbler settlement has been associated with productive northeast facing slopes in some parts of its range (Wood et al. : dom_i.query(this).attr("title").trim(); 0000008443 00000 n Preadaptive and physiological features alone appear insufficient to allow many species to adapt to the desert completely. There were no differences in small- or medium-sized mammalian predator abundance between edge and interior. }) After developing a Cerulean warbler “recognizer”, Song Scope found 4,328 potential Cerulean vocalizations of which 1,552 could be confirmed with only one hour of human labor. Pages 455–473 in Ecology and conservation of neotropical migrant landbirds. Roth, K. L. 2004. 0000008676 00000 n 0000017833 00000 n imgMarginTop = imgMarginTop.replace("px",""); Average territory size was 1.04 ha (N = 18). 0000229705 00000 n 0000003454 00000 n In winter, its home is the Andes, from Venezuela south to Bolivia. In addition, the conservation practices that create or enhance Cerulean Warbler habitat also help in recovering historically mismanaged forests. The Appalachian Region is known for its extensive tracts of mature hardwood forest and high biodiversity, including that of songbirds. However, several non-mutually exclusive hypotheses can explain this relationship. Cary, North Carolina, USA. ). SAUER, J. R., J. E. HINES, AND J. FALLON. Singing and foraging were the most common of 11 observed behavioral activities (81.6%), while maintenance and mating behaviors were uncommonly observed. We estimated site occupancy rates for two anuran species at 32 wetland sites in Maryland, USA, from data collected during 2000 as part of an amphibian monitoring program, Frog-watch USA. Although Kentucky likely supports one of the largest breeding populations of the species, no information exists on cerulean warbler habitat selection within the state. 0000007580 00000 n 0000003300 00000 n Generalizations about nest predators and edges should thus be made with caution, and conservation plans should consider the composition of local nest predator assemblages in order to predict potential impacts on nesting birds in edge habitat. The open-source system from the 3D printer delivers high-resolution images like commercial microscopes at hundreds of times the price. 0000015579 00000 n Recent article: http://www.srs.fs.usda.gov/about/newsrelease/nr_2004-02-02-warblers.htm CONTACT: Paul Hamel, Research Wildlife Ecologist. Hamel is part of a new international effort to determine the status of the cerulean warbler in both the breeding and nonbreeding ranges and to promote conservation efforts based on sound science. var count = 1; They are … We hypothesized that forest gaps and adjacent closed-canopy forest would differ in bird density, richness, diversity, and relative abundances of some species. The general physiological similarity of desert and nondesert birds, however, has led to the conclusion that birds have no special adaptations to the desert (Miller 1963). 612 Tree/Shrub Establishment Fifty percent of all territories were on ridges. Nesting Nest Placement.
