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. Sutherland, Kandyd Szuba, David White, Allen Woodliffe, and Katharine Yagi. This species has also experienced a significant long-term population increase and northward expansion in its core range in the United States. A female Hooded Warbler banded at the SWCR site in Ontario in July 2000 was at least 11 years old when last re-sighted in July 2009 (BSC unpubl. Does male extra-territory foray effort affect fertilization success in hooded warblers Wilsonia citrina? A summary of the breeding status of Hooded Warblers in Ontario. Collins, and E.H. Dunn. ** Formerly described as “Not In Any Category”, or “No Designation Required.”. BREEDING HABITAT. 2011). 2011). Available population models are limited by the lack of information on the scope and scale of dispersal movements, especially the lack of quantitative measures of adult emigration rates (see dispersal and migration). James. Even so, this species often succeeds in raising two broods to fledging in a single breeding season (early May through September in Ontario). Other migrants included a female Summer Tanager, Rose-breasted Grosbeak, two Yellow-billed Cuckoos and 11 warbler species including Cape May, Ovenbird, Blue-winged and Yellow-throated. 2007 Surveys of Acadian Flycatcher & Hooded Warbler in southern Ontario. Thursday, September 1st It's nice to see that migration is happening and new birds are arriving from up north. Juvenile birds (recent fledglings) of both sexes have a dull yellowish plumage with no head markings. Moorman. In most squares within the breeding range of this species, at least 25 point counts were completed (mostly at predetermined roadside locations). University of Waterloo Press, Waterloo, ON. Survival of fledgling Hooded Warblers (Wilsonia citrina) in small and large forest fragments. BBS data have been used to calculate population estimates and population trends at various geographic scales (Rich et al. 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. Partners in Flight North American Landbird Conservation Plan. Hooded Warbler population counts and estimates for southern Ontario in 1988, 1997, 1998, 2002 and 2007 (data from Gartshore 1988; Heagy, Table 2. Committee on the Status of Endangered Wildlife in Canada, Ottawa, ON. 2011; NatureServe 2011). 2005). 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. The Hooded Warbler is protected in Canada under the Migratory Birds Convention Act (MBCA 1994). Information on dispersal in this species is limited (Chiver et al. 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. Explore Birds of the World to learn more. This estimate seems reasonable given the amount of potentially occupied habitat that was not surveyed, the clumped breeding distribution of the species, and the overall intensity and distribution of the survey effort during this 10-year period. Hooded Warblers construct their nests in a wide array of plant species (Chiver et al. The breeding biology of the population in southern Ontario has been the focus of several studies at core sites, including longer-term work at two large (>1000 ha) public forest complexes with the largest known Hooded Warbler population in Canada: the South Walsingham Forest in 1988-98, and the St. Williams Forest (now St. Williams Conservation Reserve, SWCR) in 1999-2010 (both in Norfolk County). Reforestation efforts in the early- to mid-20th century to stabilize areas of erosion-prone sandy soils in southern Ontario have, however, resulted in tracts of pine plantations that have matured to a point where they now provide suitable breeding habitat for this species (Badzinski 2007). Historical records of the Hooded Warbler have been summarized by Baillie (1925), Gartshore (1988), Austen et al. Second clutches are typically smaller than first clutches. National Recovery Plan No. Due to its Threatened status, the Hooded Warbler was identified as a Priority Species in the landbird conservation plan for southern Ontario (OPIF 2008). 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). Canada’s first Hooded Warbler nest prelude to population expansion of today. 2011. Auk 125(1):183-191. However, the ecological mechanisms underlying the correlations identified in these empirical studies are not understood. Austen, M.J.W., M.D. Hooded Warbler Migratory Habitat. 1998. Planning Act (PA). BBS routes consist of 50 roadside points along randomly selected, stratified routes across the United States and southern Canada. Page, A.M. and M.D. Dispersal of many young and some adults over longer distances is considered likely but has not been documented (e.g., there are no banding encounters involving longer distance movements of birds captured or banded in Canada, Brewer et al. The continued absence of breeding Hooded Warblers in the Kingston area is surprising given the proximity of breeding populations in New York, an increase in forest cover, and the species’ status as a regular rare spring migrant there for more than 30 years (Austen et al. Although not statistically significant, the 10-year trend is equivalent to an 80% increase. 2011). John Carreau. 2011). Black-throated gray warbler. 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). Bird Studies Canada, Port Rowan, ON. Woodsworth, B.T. Most public and private sites are working forests that are being actively managed for timber and fuelwood production, as well as being used for recreation (off-road motorized vehicles, hunting, hiking, etc., BSC unpubl. There is no evidence of population structuring within the Canadian or North American population of this species. © Her Majesty the Queen in Right of Canada, 2012.Catalogue No. A few males are polygynous and have two females, and a variable proportion of territorial males remain unmated. Hanula, S.Horn and M.D. 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). Moreover, a recent population model of SWCR population dynamics suggests that breeding numbers are maintained through frequent dispersal into and out of the population, a phenomenon that likely also occurs in other breeding areas (Calvert and Badzinski in prep.). 1997. In the forest undergrowth, this skulking warbler seems to call attention to itself by frequently fanning its tail quickly … 2007. 1987. A surprise was a calling Cooper’s Hawk that alighted on several of the parade ground buttonwoods. 2011). Cadman, M.D., P.F.J. 1989; Freemark and Collins 1992; Norris et al.

Head on over to Habitat Network to learn about which native species are good matches for your yard and more. Ontario Landbird Conservation Plan: Lower Great Lakes/St. There is some evidence that young birds may scout out breeding territories before undertaking their first migration (Chiver et al. Loss and degradation of habitat at migration stopover sites and on the wintering grounds have been identified as potential threats, but the magnitude of these threats is unknown. Hooded Warbler nesting success adjacent to group-selection and clearcut edges in a southeastern bottomland forest. 2011). data; Badzinski and Calvert in prep.). A wildlife species facing imminent extirpation or extinction. University of Waterloo Press, Waterloo, ON. In the past decade, Hooded Warblers have expanded in the Greater Toronto Area, particularly in Durham Region and Northumberland County east of Toronto. 1997. Conversely, some studies have found that selective logging, insect outbreaks, and severe weather events that open the forest canopy can increase local Hooded Warbler breeding densities (see Breeding Habitat requirements). 2011. Forest Ecology and Management 261:111-119. 1999). Within southern Ontario, most of the increase in forest cover has occurred in southeastern Ontario and elsewhere in the Lake Simcoe-Rideau region, which now has 35% forest cover (and 56% agriculture) (OMNR 2006). Females weave together bark, fine grasses, and plant down into a cup. Breeding latitude and timing of spring migration in songbirds crossing the Gulf of Mexico. During migration this species is found in wooded habitats, including edge and canopy gaps in mature forests in inland situations, and coastal woodlands and wooded islands along the Gulf Coast in southeastern United States (Langin et al. Directed searches at known and potential breeding locations in southern Ontario in 1997, 1998, 2002, and 2007 also documented ongoing increases in population size, number of occupied sites, and breeding distribution. Brown, D.R., T.W. Threatened (T) Is there an observed continuing decline in index of area of occupancy? But as impressive as they are, these charismatic critters have nothing on the Blackpoll Warbler—an unassuming bird with one of the most ambitious migration routes on the planet. Check-list of North American birds, 7th edition. 2003; Heagy and Badzinski 2008). Weir, R.D. 2007. The hooded warbler (Setophaga citrina) is a New World warbler. 2011; BSC unpubl. 2011. Hurricane Katrina impacts the breeding bird community in a bottomland hardwood forest of the Pearl River basin, Louisiana. Stutchbury. At the start of OBBA1 in 1981, the species was considered “a straggler that occasionally bred in Ontario” (Sutherland and Gartshore 1987). 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 … The Hooded Warbler feeds mostly on insects, small spiders and other arthropods in all seasons (Chiver et al. Journal of Field Ornithology: 11-20. Population models using SWCR data show that growth rate is most sensitive to local adult survivorship (Calvert and Badzinski in prep.). The count of 436 territories reported in 2007 is almost five times the 88+ known territories reported in 1997, just 10 years earlier. 2011). Hitch, A.T., and P.L. 8 +iv pp. The observed pattern of northward range expansion of the Hooded Warbler (and other “southern” landbird species), as depicted by BBS and BBA data from recent decades, is generally consistent with the pattern of change in various climatic variables associated with climate warming (Matthews et al. 1995). Reason for designation In Canada, the range and abundance of this forest-nesting species have increased substantially since the species was last assessed. 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.

In the 2002 and 2007 surveys, these “mega-sites” were each split into several smaller parcels and considered as multiple sites. Overwinter survival does not appear to vary by habitat (Conway et al. Becker, and P.S. Larson, B. J.L. Quantitative information on trends in forest quality is not available, but most forest habitat within the current Ontario breeding range is relatively young; only about 12% of southern Ontario forest is classified as mature, and < 1% is considered old-growth (OMNR 2006). 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). Walters, B.J. Available habitat in southern Ontario does not appear to be saturated, even at core sites such as SWCR, which have been occupied for more than a decade (Melles et al. 140/2005. 19 pp. Bird Studies Canada, Environment Canada, Ontario Field Ornithologists, Ontario Ministry of Natural Resources, and Ontario Nature, Toronto. 2002. 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. COSEWIC status reports are working documents used in assigning the status of wildlife species suspected of being at risk. Would immigrants be adapted to survive in Canada? Ratcliffe. 15 pp. 28 pp. New occurrences away from the core breeding areas are often identified as a result of these incidental observations. Bird Banding Laboratory. In: IUCN 2009. 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. Counts have also increased in areas east and northeast of Norfolk, particularly in Niagara and Hamilton Regions, but have not increased in other parts of southwestern Ontario, where numbers remain generally low. Parker, T.H., B.M. A trend analysis of LPBO migration count data for Hooded Warbler for 1961-2010 was provided by Tara Crewe (BSC, pers. 2007). 2008. 2002. DRAFT National Recovery Strategy for Carolinian Woodlands and Associated Species at Risk: Phase 1. Forest health and diversity across southern Ontario is also compromised due to various native and exotic invasive plants, pests, and diseases (e.g., Scarr et al. An analysis of range-wide occurrence data shows that a high proportion (80%) of the total Hooded Warbler population occurs in landscapes with contiguous forest cover (Donovan and Flather 2002). There are now 34 warbler species within this genus (AOU 2011). 71 pp. 1994. Females can build a nest in as little as 2 days, but it often takes them 5–6 days to complete a nest. Species at Risk Act, Statutes of Canada 2002, Chapter 29. http://laws.justice.gc.ca/en/s-15.3/text.html. Cadman, P. Carson, K. Elliott, M.E. data; and 76% to 83% in smaller woodlots near SWCR, Bisson and Stutchbury 1998; Eng 2007; Melles 2007) are lower than rates reported in areas of high forest cover (e.g., 94% paired males at a site in Pennsylvania, Chiver et al. The breeding range of this species has been expanding northwards for at least 40 years. Cadman. 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). Food supply does not appear to be a limiting factor during the breeding season or during spring and fall migration (Nagy and Smith 1997; Buehler et al. 2011; Calvert and Badzinski in prep.). Stutchbury. Hooded Warbler breeding evidence during Ontario Breeding Bird Atlases, 1981-1985 and 2001-2005 (based on Cadman et al. Jalava, J.V., J. D. Ambrose and N.S. SARA prohibits harming or possessing a listed species, or damaging its residence or critical habitat. 2000; Parker et al. Provided that there is an ongoing supply of suitable habitat, then it is likely that the Hooded Warbler population will continue to be stable, or increasing. These were, and what plumages they possessed - like everything American, Flashier and grander by … 1998). Twedt, D.J., J.M. 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. By the end of OBBA1, it was clear that Hooded Warbler was a rare but regular breeding species in Ontario and it was suggested that the species “probably always bred in southern Ontario in small numbers but generally escaped notice” (Sutherland and Gartshore 1987). United States Geological Survey, Patuxtent Wildlife Research Center, Laurel, MD. Hooded Warblers are common and their populations increased by around 1% per year between 1966 and 2015, according to the North American Breeding Bird Survey. Landscape ecology of birds breeding in temperate forest fragments. thesis, Dept. Stutchbury, and N.C. Kopysh. Forests within the Carolinian region in particular are highly fragmented, with < 500 patches over 100 ha in size (Flaxman 2004). Powell, and J.D.

There is no reason to expect that the population will not continue to grow and expand, at least over the next ten years. 2011). Federation of Ontario Naturalists. Cover illustration/photo: Hooded Warbler -- Photo: Ron Kingswood. Stutchbury. Data from all sources show a consistent pattern of strong increases in the abundance and distribution of the Hooded Warbler population in Canada. 2010. 1992. BBS population trends for Pennsylvania and Ohio, respectively, are 3.9 and 6.1%/yr for 1966-2009, and 4.4 and 6.4%/yr for 1999-2009 and are statistically significant (Sauer et al. This legislation prohibits the possession or sale of migratory birds and their nests, and activities that are harmful to migratory birds, their eggs, or their nests, except as permitted under the Migratory Bird Regulations. 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). Kingston Field Naturalists, Kingston, Ontario.611 pp. 1994. Sutherland, G.G. Norris, D.R, and B.J.M. 2002; Lacki et al. These limits assume that breeding evidence was reported for 50-85% of all cells occupied between 2001 and 2010. The current draft of the proposed federal Recovery Strategy identifies 56 sites in Ontario with critical habitat for this species, with a total area of about 9000 ha. 171 pp. A List of Municipalities with Bylaws, Ontario Woodlot Association, updated August 2010. 1998.

The 1997 and 1998 surveys covered 51 sites whereas the 2002 and 2007 surveys included 184 and 168 sites, respectively. Pither, R. 1997. Although subjective, these assumptions seem reasonable given the extent of known and suitable habitat not checked in 2007, and available population trend information for Ontario (see Fluctuations and trends) and adjacent jurisdictions (see Rescue effect). The total global breeding range (extent of occurrence) is approximately 2,000,000 km², while the total global wintering range is much smaller at approximately 750,000 km² (derived from Ridgeley et al. In the United States, the species is nationally secure (N5B) and is ranked as secure (S5) or apparently secure (S) in most jurisdictions.

The lower value of 1000 individuals is very conservative and assumes that the 2007 survey included >85% of the total population (i.e., detected all or most of the territorial birds at the sites that were covered, few or no birds were present elsewhere) and that the population has been stable since 2007. 2003. 2011). 2002; Hetzel and Leberg 2006; Chiver et al. Dawson, and B.A. 2011). The same could be said for Hooded Warbler – seen in Britain in 1970 and 1992 (and never in Ireland), another is overdue, given that Corvo has scored no fewer than four since 2005. Like many of the ruby-throated hummingbirds that make their home in the United States for the summer, the hooded warbler’s fall migration takes it across the vast open waters of the Gulf of Mexico, crossing to the Yucatan and then dispersing from there to various points in Central America. 2002. Longer-term changes in the extent and distribution of woodlands in southern Ontario have been described by Larson et al. The Hooded Warbler is socially monogamous with most breeding males having a single female on their territory. Hooded Warbler spring migration count indices 1961-2010 and trend at Long Point Bird Observatory, Norfolk County, Ontario (courtesy of Tara Crewe, Bird Studies Canada). Hooded Warbler breeding evidence during Ontario Breeding Bird Atlases, 1981-1985 and 2001-2005 (based on Cadman, Figure 4. Ridgeley, R.S., T.F. Sherry, and J. Harris. 128 pp. Ontario Ministry of Natural Resources, Peterborough, ON. It appears that a greater proportion of the population uses the shorter Gulf of Mexico crossing in spring migration than in fall, and that adults are more likely than immature birds to cross the Gulf in the fall (Chiver et al. The Canadian Wildlife Service, Environment Canada, provides full administrative and financial support to the COSEWIC Secretariat. Many forested areas on private land in southern Ontario have never been searched for this species. The Committee meets to consider status reports on candidate species.
