hooded warbler migration

This section of the report draws on information from the US range as summarized in the revised Birds of North America species account (Chiver et al. Porter. Mark-recapture estimates of local survivorship (birds that survive and return to the same breeding site) for SWCR are 9.8% (SE=1.6%) for young, and 48.0% (SE=2.9%) for adults (Calvert and Badzinski in prep.). Hooded warblers are very rare vagrants to western Europe. Gartshore, M.E. A category that applies when the available information is insufficient (a) to resolve a species’ eligibility for assessment or (b) to permit an assessment of the species’ risk of extinction. McCracken. High densities occur in forests that have been selectively logged within the past 5-15 years, provided that many large-trees have been retained (Whittam et al. However, habitat degradation at breeding sites and habitat loss and degradation at migration stopover sites and on the wintering grounds are potential threats. Annand, E.M. and F.R. WHEN TO GO: This tour is timed when the peak of warbler migration occurs in the Midwest – around the middle two weeks of May – but also after the southern warblers have arrived on their breeding grounds in Kentucky and … Evans Ogden, L.J. 2011). Ithaca, New York. Both sexes have olive-green upperparts, a bright yellow underside, and characteristic white tailspots that are visible when the tail is fanned out. 2005. 2007). plus appendices. Stutchbury. 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. Blancher, P., M.D. Robbins, C.S., D.K. John Carreau. Climate change appears to be an important factor in the observed range expansion. Efforts to model Hooded Warbler habitat in Ontario at a landscape scale using satellite imagery have had limited success because the coarse spatial and temporal resolution of the Landsat images are not well suited to identifying the specific fine-grained habitat requirements of this species (Pither 1997; Flaxman 2004; Pasher et al. 2011). Laurel MD. However, there is also evidence that the Hooded Warbler population is very dynamic, and is characterized by high levels of immigration and emigration in response to habitat quality. During the second atlas, 5-minute point counts were used to provide relative abundance information. 8 +iv pp. American Ornithologists’ Union. Accessed 26 April 2011. Hooded Warblers are common in moist leafy woodlands of the Southeast.. Hooded Warbler (Wilsonia citrina) Status: Vagrant. Unpublished report for the Acadian Flycatcher & Hooded Warbler Recovery Team. 2011). In winter, males compete for territories in humid lowland forest and females occupy mainly disturbed scrub or secondary forest. Hooded Warblers capture insects and spiders by picking them off leaves or the ground and by flying up to grab them, a foraging technique called hawking. Hooded Warbler nesting success adjacent to group-selection and clearcut edges in a southeastern bottomland forest. Due to its predilection for early successional canopy gaps, this species consistently occurs at higher densities in mature forests that have been subject to selective logging within the past 2 to 20 years than in forests that have not been logged for at least 30 to 50 years (Annand and Thompson 1997; Robinson and Robinson 1999; Hetzel and Leberg 2006; Eng 2007). Females lack the bold black hood, but their yellow cheeks still stand out. The authors also acknowledge the collective contributions of the hundreds of volunteers who have helped monitor this species through their participation in the Ontario Breeding Bird Atlas projects and the North American Breeding Bird Survey. Recent changes (AOU 2011) have now placed Hooded Warbler within the genus formerly known as Dendroica; now named Setophaga. It appears that the current population in Canada may already have achieved the population objective set in the proposed Recovery Strategy, specifically, of having 500 breeding pairs distributed within the species’ current Ontario range (Environment Canada 2011). McCracken, C.M. 2009. The Hooded Warbler is identified as one of 195 species of Continental Importance in the North American Landbird Conservation Plan because 98% of its global population breeds within the Eastern Avifaunal Biome, and that avifaunal region has a very high stewardship responsibility for the conservation of this species (Rich et al. Cadman, and R.D. Brown, D.R., T.W. 2004. Canadian Field-Naturalist 39:150-151. Population dynamics of a threatened neotropical migrant at the edge of its range. There is no reason to expect that the population will not continue to grow and expand, at least over the next ten years. Journal of Avian Biology 40:309-316. Stutchbury. Cornell Lab of Ornithology, Ithaca, New York, USA. Environment Canada, Canadian Wildlife Service, Ottawa, ON. Long Point Bird Observatory, Port Rowan, ON. 2011).

Each point is surveyed once (3-minute point count) by an experienced birder during the breeding season. 340 pp. (2011). Due to this species’ dependence on early-successional nesting habitat, Hooded Warbler occupancy of large sites tends to shift and vary over time and can fluctuate moderately (e.g., 11-23 territories at South Walsingham Forest from 1985-2002 and 37-67 territories at SWCR from 1999-2010, BSC unpubl. The Hooded Warbler database maintained by Bird Studies Canada represents the cumulative results of hundreds of field days of effort by numerous dedicated field biologists and assistants.

Females often wrap dead leaves around the bottom of the nest cup as well, making the nest look like a clump of dead leaves. 2007). 2007. The index of area of occupancy (IAO) was calculated by assigning available geo-referenced breeding evidence data to standard 2 km x 2 km cells. Committee on the Status of Endangered Wildlife in Canada. 2008. 2011). plus appendices. Only in the past decade, with completion of OBBA2 and additional intensive surveys, has uncertainty as to whether the observed increase was real or due entirely to increased search effort and searcher efficiency (see Austen et al. 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. Land ownership and habitat protection statistics for the known population overestimate the overall level of protection of the population because survey effort has focused on protected areas and public lands. Fitzgerald. Bird Studies Canada, Port Rowan, ON. United States Geological Survey, Patuxtent Wildlife Research Center, Laurel, MD. Website: [accessed December 2010]. 2011. comm., October 2011). The results (by county/region) of the four extensive Hooded Warbler surveys carried out in Ontario between 1997 and 2007 are presented in Table 1, along with the 1988 population estimate by region as prepared by Gartshore (1988). Recovery strategy for the Acadian Flycatcher (Empidonax virescens) and Hooded Warbler (Wilsonia citrina) in Canada [Proposed]. Sorenson, J.L. Pairing rates at study sites in Ontario (e.g., 75%, range 60% to 90% at SWCR, BSC unpubl. and B.J.M. Estimated percent of continuing decline in total number of mature individuals within 5 years. One study comparing birds wintering in mature versus early-successional forest habitats in Belize found no evidence of a large difference in overwinter survival (Conway et al. Special Concern (SC)* The Hooded Warbler flits through shrubby understories in eastern forests, flicking its tail to show off its white tail feathers. ): Atlas of the Breeding Birds of Ontario. At SWCR, single-brooded pairs that are parasitized have the lowest seasonal productivity (0.8 nestlings surviving to 5 days post-hatch), compared to double-brooded pairs that are not parasitized (5.2 day-5 nestlings) (Badzinski and Calvert in prep). Iverson, A.M. Prasad, S.N. A species, subspecies, variety, or geographically or genetically distinct population of animal, plant or other organism, other than a bacterium or virus, that is wild by nature and is either native to Canada or has extended its range into Canada without human intervention and has been present in Canada for at least 50 years. 2011). Pond, M.D. Extensive targeted searches of known and potential Hooded Warbler (and Acadian Flycatcher) breeding habitat in southern Ontario were carried out in 1997, 1998, 2002, and 2007 (Heagy et al. 2011). The Hooded Warbler is frequently double-brooded and will re-nest up to three times if previous nests are unsuccessful (Evans Ogden and Stutchbury 1996; Howlett and Stutchbury 2003). The Hooded Warbler is a small songbird (body length: 13 cm, body mass: 11 g) with a striking plumage and a distinctive vocal repertoire. Hooded warbler upperparts are olive green; underparts are yellow. The Hooded Warbler was first reported in Canada before 1860 at Hamilton, Ontario and it was considered “a rare migrant” in Ontario during the early 1900s (Baillie 1925). M.Sc. Unpublished report to the Endangered Species Recovery Fund, World Wildlife Fund Canada and Canadian Wildlife Service. 2011). The Hooded Warbler is a forest-obligate species and breeds in mature forests in upland or bottomland situations (Chiver et al. Riley, E.A. Friesen, L., M.D. ** Formerly described as “Not In Any Category”, or “No Designation Required.”. Butcher, D. Demarest, W.C. Hunter, E. Inigo-Elias, J.A.

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. In prep. Hooded Warblers breeding in southern Ontario and in fragmented landscapes in the US have low productivity relative to birds breeding in areas with continuous forest cover (Eng 2007; Badzinski and Calvert in prep. 2007). 2009). Individuals often return to the same overwintering territory in subsequent years (Chiver et al. Norris, D.R, and B.J.M. Landscape ecology of birds breeding in temperate forest fragments. As with other small passerines, the expected life span is short, and the generation time (average age of breeding adults) is likely about 2-3 years. 15 pp. Search effort in forested areas north and east of the Carolinian region consisted of incidental reports from volunteers and researchers. The estimated global breeding population is 5.2 million and has approximately doubled since 1970, according to Partners in Flight. 2007). There is strong sexual segregation by habitat, with males preferring closed canopy forests whereas females prefer open woodland, early successional forest, and scrub habitats (Lynch et al. For example, Melles (2007, 2011) found that the cooler temperatures were positively related to a lack of range expansion and that the number of extreme weather days in July was an important predictor of Hooded Warbler presence in Ontario. The small Canadian population is contiguous with much larger breeding populations of the northern United States. Each year it flies all the way to the UK from Africa, travelling more than 8,000 kilometres (5,000 miles) across seas, mountains and … Several municipalities have designated significant wildlife habitat and significant woodlands in their Official Plans. Alfred A. Knopf, New York, NY, USA. Hooded Warblers experience relatively high nest predation rates (e.g., 25-44%) across their range (Sargent et al. COSEWIC -- Committee on the Status of Endangered Wildlife in Canada. Nesting success of forest songbirds in mixed mesophytic forests in eastern Kentucky. Couturier (eds.).

The Canadian breeding distribution is restricted to southern Ontario, where it is considered to be a rare or locally uncommon breeder. 2002; Hetzel and Leberg 2006; Chiver et al. Figure 3. Lutmerding, J. 'Black-throated Green Warbler', 'Black-throated Blue', 'Chestnut-sided', - even 'Hooded ' and 'Yellowthroat' are quite helpful, as long as the birds are in spring plumage. 2011. Data from southern Ontario are consistent with information summarized in Chiver et al. Hooded Warblers exhibit low fidelity to their natal sites, whereas adults frequently return to the same breeding site, and males in particular often return to the same territory (Howlett and Stutchbury 2003; Melles et al. Couturier (eds.). 140/2005. The male's bright yellow cheeks and forehead surrounded by a black hood and throat will surely capture you. This species has also experienced a significant long-term population increase and northward expansion in its core range in the United States. Range: Post-breeding migration This map depicts the range boundary, defined as the areas where the species is estimated to occur at a rate of 5% or more for at least one week within the post-breeding migration season. Pp.524-525 In Cadman, M.D., D.A. The Hooded Warbler feeds mostly on insects, small spiders and other arthropods in all seasons (Chiver et al. Atlas of the Breeding Birds of Ontario, 2001-2005. The range-wide BBS data also show statistically significant increases of 40% (3.4%/yr) for 1999-2009 and over 100% (1.8%/yr) for 1966-2009 (Figure 4). Parasitized nests fledge fewer host young than non-parasitized nests (Chiver et al. A few males are polygynous and have two females, and a variable proportion of territorial males remain unmated. Hooded Warbler breeding evidence during Ontario Breeding Bird Atlases, 1981-1985 and 2001-2005 (based on Cadman et al. Various demographic studies in Ontario (and also in northwestern Pennsylvania) found evidence of depressed productivity and survival, leading to the suggestion that Hooded Warbler populations in fragmented landscapes at the northern range periphery may be population sinks, where local productivity is not sufficient to offset adult mortality/dispersal (Eng 2007; Rush and Stutchbury 2008; Chiver et al. Page, Annette M. and M.D. 2011. Survival of fledgling Hooded Warblers (Wilsonia citrina) in small and large forest fragments. Thursday, September 1st It's nice to see that migration is happening and new birds are arriving from up north. The upper value of 2000 individuals assumes that the 2007 survey detected only about 50% of the total population and that the population has increased 20% (~5%/yr) since 2007. Forest Ecology and Management 260:1241-1250. Smith. Ridgeley, R.S., T.F. Hanula, S.Horn and M.D. In states bordering its Canadian range, the Hooded Warbler is ranked as secure (S5) in New York and Ohio, apparently secure (S4) in Pennsylvania, vulnerable (S3) in Michigan and Minnesota, and imperiled to vulnerable (S2S3) in Wisconsin (NatureServe 2011). The Hooded Warbler winters in humid to semi-humid lowland forest and scrub habitats (Chiver et al. IUCN Red List of Threatened Species. 2011). BBS data have been used to calculate population estimates and population trends at various geographic scales (Rich et al. Endangered Species Act, 2007. 2003; Heagy and Badzinski 2008). Online database, updated 8 August 2011. http://www.aou.org/checklist/north/index.php [accessed 7 November 2011]. Kyser, and L.M. Only five more nests were found over the following 36 years (Gartshore 1988). Bowen, J.C. Kilgo, C.E. Does breeding density covary with extra-pair fertilizations in Hooded Warblers? Francis and R. S.

Predation is the primary cause of nest failure at sites in Ontario and elsewhere and has a much larger influence on overall productivity than does nest parasitism (Stutchbury 1997; Eng 2007; Chiver et al. 1994. like most warblers - will be most visible over the spring/fall migration periods (May/June and September/October) even during migration will favor dense forest understory and forest edge brush; Hooded Warbler Behavior (What to look for) frequently twitches tail and exposes white outer tail feathers Definition of the (DD) category revised in 2006. Seasonal Bird News. Cream-colored with scattered brown spots. Other studies in southwestern Ontario reported similar rates (Bisson and Stutchbury 1998; Badzinski 2003; Melles 2007). 2007). The incubation period is 12 days; incubation and brooding is by the female only and begins with the laying of the last egg.

Zook. Federation of Ontario Naturalists. Changes in Bird Distribution between Atlases. data). Adult females have a variable amount of black on the head, ranging from none (typically during the first breeding season only) to almost a full black hood in some individuals. Although males are detected more frequently than females on the breeding grounds, similar numbers are captured during migration and the adult sex ratio is presumed to be approximately equal (Eng 2007; Melles 2007). Journal of Avian Biology 29:145-154. Females in small fragments do not travel far (<130 m) and therefore have limited mate choice relative to females in continuous forest (Norris and Stutchbury 2002). Second clutches are typically smaller than first clutches. Stutchbury, B.J.M. 86 pp. National Museum of Canada, Ottawa, ON. Wilson Bulletin 115(3):277-284. Hooded Warblers construct their nests in a wide array of plant species (Chiver et al. The breeding range of this species corresponds closely to the North American Eastern Deciduous Forest Biome, being widely distributed in forested landscapes east of the Great Plains.
