hooded warbler migration

2007. Disentangling habitat and social drivers of nesting patterns in songbirds. Unpublished report produced for Canadian Wildlife Service. Determinants of between-season site, territory, and mate fidelity in Hooded Warblers (Wilsonia citrina). Hanula, S.Horn and M.D. Auk 114(4):619-627. Wilson Bulletin 109(4):643-649. A small breeding population in the Ganaraska Forest (mostly in Durham Region) in south-central Ontario, 200 km northeast of Norfolk County, has been studied since it was first reported in 2006 (Walters and Nol 2011). Long-distance dispersal patterns of male Cerulean Warblers (Dendroica cerulea) measured by stable-hydrogen isotopes. Population counts and estimates for the Hooded Warbler in Canada, Committee on the Status of Endangered Wildlife in Canada, Wild Species 2005: The General Status of Species in Canada, NatureServe Explorer: An Online Encyclopedia of Life, Ontario Ministry of Muncipal Affairs and Housing, Generation time (usually average age of parents in the population). The Canadian breeding distribution is restricted to southern Ontario, where it is considered to be a rare or locally uncommon breeder. Sexual differences in gap-crossing ability of a forest songbird in a fragmented landscape revealed through radiotracking. 2007. Pete Dunne's essential field guide companion. The Hooded Warbler is a long-distance migrant that breeds in eastern North America and winters in Mexico, Central America and the Caribbean. 2011). These ranks are being revised to N4B and S4B (Apparently Secure) to reflect current abundance and distribution and increasing population trend (D.A. These preferences are not absolute: Hooded Warblers will use forest edges and they can nest successfully in very small forest patches (e.g., <5 ha in Pennsylvania, as small as 10 ha in Ontario) in areas with high regional forest cover (Norris et al. 2011). There is no substantive evidence to support the alternate view that this species likely occurred widely in the extensive forest habitat present before European settlement but subsequently declined or disappeared due to habitat loss in the 1800s, as suggested in previous status reports (Page and Cadman 1994; James 2000). Nesting success and nest-site selection by a neotropical migrant in a fragmented landscape. 2003. 140/2005. Both sexes have olive-green upperparts, a bright yellow underside, and characteristic white tailspots that are visible when the tail is fanned out. Wintering habitat in Mexico and Central America has been affected by deforestation and agricultural intensification (Conway et al. Auk 125(1):183-191. Draft manuscript, April 2010. data). It is a trans-Gulf migrant, wintering mostly in southeastern Mexico and on the Caribbean slope of northern Central America. The small Canadian population is contiguous with much larger breeding populations of the northern United States. Page, Annette M. and M.D. A trend analysis of LPBO migration count data for Hooded Warbler for 1961-2010 was provided by Tara Crewe (BSC, pers. Baker. data, 2004-05). Changes in wintering distribution have not been documented. As with other species dependent on early successional habitats, dispersal is considered to be an important factor in Hooded Warbler population dynamics (Calvert and Badzinski in prep.). Ontario Landbird Conservation Plan: Lower Great Lakes/St. 2008. Wilsonia citrina. Stutchbury. Howlett, J.S. Alfred A. Knopf, New York, NY, USA. During migration Hooded Warblers prefer any wooded habitat with a dense understory. The paternity of Hooded Warbler nestlings has not been studied in Ontario. ; Chiver et al. Most atlas squares (10 km x 10 km) within the Canadian breeding range of this species received a minimum of 20 hours of coverage, a level of effort considered adequate to detect the majority of species occurring in a square (Cadman et al. 2002. During the mid- to late-20th century, the breeding range of the Hooded Warbler expanded. James, R.D. Further to the Terms and conditions for this website, some of the photos, drawings, and graphical elements found in material produced by COSEWIC are subject to copyrights held by other organizations and by individuals. The Hooded Warbler is a forest-obligate species and breeds in mature forests in upland or bottomland situations (Chiver et al. Hooded Warbler. data). Ithaca, New York. Calvert, A.M. and D. Badzinski. Smithsonian Institution Press, Washington, DC. They spend the winter in lowland tropical forest, scrub, and brushy fields. 2011). The Appalachian range of mountains running through east Tennessee is along the major eastern flyway and is a great spot to do some spring migration birding. Unpublished report to the Endangered Species Recovery Fund, World Wildlife Fund Canada and Canadian Wildlife Service. Sibley, D. A. Due to its Threatened status, the Hooded Warbler was identified as a Priority Species in the landbird conservation plan for southern Ontario (OPIF 2008). Auk 102: 714-721. Lawrence Plain (North American Bird Conservation Region 13), Priorities, Objectives and Recommended Actions. The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assesses the national status of wild species, subspecies, varieties, or other designatable units that are considered to be at risk in Canada. Another water body that provided me with some excellent views of warblers was the Haw River. Badzinski (2007) provided a population estimate of 300 Hooded Warbler territories based on the OBBA2 data and some additional data from the 2006 breeding season. Nest site characteristics of Hooded Warblers at the northern edge of their breeding range. Survey effort at most other sites was similar in all surveys (Heagy and Badzinski 2008). 80 pp. Get Instant ID help for 650+ North American birds. 16 pp. Over half of the known Hooded Warbler sites in Ontario are on publicly owned lands, particularly working forests owned by local conservation authorities or municipalities. Creating a bird-friendly backyard can provide excellent stopover habitat to support warblers as they migrate to and from the breeding grounds. Atlas of climate change effects in 150 bird species of the Eastern United States. 2008. Fledgling care and male parental effort in the Hooded Warbler (Wilsonia citrina). Stutchbury. CW69-14/11-2012E-PDFISBN 978-1-100-20709-4. Females construct distinctive cup-shaped nests typically in low shrubs, tree saplings or ferns. “We almost always see hooded warblers in the same area of the forest and I try to take photos of them.” Stutchbury, W.H. Norris, D.R, and B.J.M. Tara Crewe of Bird Studies Canada provided the graph used in Figure 3.
