In Canada, the current Barn Swallow population is estimated at about 2.45 million breeding pairs (about 4.9 million mature individuals). Iverson (1988) reported that female Barn Swallows moved an average of 1.6 km from the previous year’s nesting site (n=5). 1996. In addition, changes in species occurrence (based on presence/absence data within 10 x 10 km squares) of widespread, common species like the Barn Swallow underestimate changes in actual population size (Francis et al. Bird Studies Canada, Environment Canada, Ontario Field Ornithologists, Ontario Ministry of Natural Resources, and Ontario Nature, Toronto, xxii + 706 pp. 2010). Factors affecting nest and site fidelity in Adirondack Barn Swallows (Hirundo rustica). Matson and J.W. Hirondelle rustique - description, habitat. This suggests that loss of foraging habitat does not, by itself, explain Barn Swallow population declines. 00:00 00:00. Elsewhere in Canada, however, the area of suitable foraging habitat may even be increasing, even in regions where Barn Swallow populations are in decline. Since the 1980s, however, data from BBS, breeding bird atlas projects and ÉPOQ all point to a significant and persistent decline of Barn Swallow populations. Beal, F.E.L. Over the most recent 10-year period (1999 to 2009), BBS data show a statistically significant decline of 3.5% per year, which represents an overall decadal decline of 30%. At the same time, the amount of open habitat needed for foraging also greatly increased. No information is available on site attachment to wintering areas. Association Québecoise des groupes d'ornithologues, Province of Quebec Society for the Protection of Birds, Canadian Wildife Service, Environment Canada, Québec Region, Montréal. Barn Swallows often cruise low, flying just a few inches above the ground or water. The species is capable of colonizing regions away from open agricultural areas as a result (e.g., logging roads in boreal forests; C. Savignac, pers. 2003) and the central part of the Northwest Territories, and south through British Columbia and the prairies (Godfrey 1986; Smith 1996; Campbell et al.

Ottawa: Minister of Public Works and Government Services Canada. In Canada, the Barn Swallow and its nests and eggs are protected under the Migratory Birds Convention Act, 1994. 2008), such as in the southern Shield region of Ontario, where it has been suggested that declines of Barn Swallows are linked to abandoned, non-productive farmlands returning to forest conditions (Cadman et al. Semenchuk, G.P. Another threat is increased nest predation from non-native predators such as Fox Squirrels (Sciurus niger) in western Canada, rats in barns, and possibly increased predation of adults from increasing populations of several native species of diurnal raptors.

Is there an observed continuing decline in number of mature individuals? 1992. James. In the Fraser River delta in British Columbia, Barn Swallows have been reported throughout the year, and spring migrants can start to appear as early as late March (Campbell et al. 1997; Brown and Brown 1999a; Cadman et al. Biotics web explorer. Email correspondence to C. Savignac. and M.J. Schmoll. Incubation, which is performed mainly by the female (Smith and Montgomerie 1991), lasts 13-14 days in Ontario (Peck and James 1987) and 12-17 days in British Columbia (Campbell et al.

Safran, R.J., C.R. 1989. Møller. July 2009. Based on results of preliminary unpublished analyses conducted by P. Taylor, who took survey effort into account, the probability of detection for Barn Swallow decreased significantly in all three Maritime provinces between atlas periods – from 0.87 to 0.53 (New Brunswick), from 0.90 to 0.67 (Nova Scotia), and from 0.93 to 0.48 (Prince Edward Island; B. Whittam pers. University of British Columbia Press, Vancouver, BC. July 2009. It also does a poor job of monitoring populations in remote, natural situations associated with cliff faces. In addition to wooden outbuildings, Barn Swallows have adapted to the increase of human infrastructure along road systems such as bridges and culverts. In North America, the main insect groups are Diptera, but insects from many other families are consumed (Brown and Brown 1999a). Wilson Bulletin 108:540-549. 2002a. They concluded that “its population has clearly not yet recovered to the level that preceded its initial decline, and consequently it is evaluated as Depleted.”.

One limitation of the BBS is that it probably does not wholly track colonial and semi-colonial species like the Barn Swallow. 2006. In the mixed-grass prairies of southern Alberta, Barn Swallows were positively associated with large fields and long wetland edges (Koper and Schmiegelow 2006). Elle hiverne en Amérique du Sud, dans le sud de l'Asie, en Micronésie, en Indonésie, en Afrique ou en Australie, suivant son lieu de reproduction. 1997. 493. Construction of bridges and culverts since the mid-1900s is also thought to be responsible for the species’ range expansion (e.g., into areas of boreal forest; C. Machtans pers. Environment Canada, Gatineau, Quebec, K1A 0H3. Although poorly understood, the main causes of the recent decline in Barn Swallow populations are thought to be: 1) loss of nesting and foraging habitats due to conversion from conventional to modern farming techniques; 2) large-scale declines (or other perturbations) in insect populations; and 3) direct and indirect mortality due to an increase in climate perturbations on the breeding grounds (cold snaps). Clutch size may also be age-related. Cadman, D.A. [accessed May 2010]. 2007). Factoring in these declines yields a current population estimate of about 4.9 million mature individuals (equivalent to about 2.45 million breeding pairs).

Adults do not defend breeding “territories” per se, but do have minimum separation distances around active nests – ranging from 1.7 m in British Columbia (Campbell et al. Ibis 141:652-659. Barclay, R.M.R. In Canada, clutch size is generally four to five eggs in the east (Ontario: range: 1-7 eggs, n = 467 nests; Peck and James 1987), and three to five in the west (British Columbia: range: 1-10 eggs, n = 1705; Campbell et al.

The SQBP database covers all regions south of the 52nd parallel and all seasons (Cyr and Larivée 1995). During the haying season, Barn Swallows are known to chase insects that flush up behind mowers. For the period 1970-2008, the ÉPOQ database shows a significant long-term decline in Barn Swallow abundance in Quebec of 2.4% per year (P < 0.001; Larivée 2009; Figure 6), representing a 60% decline over 38 years. The nestling period is 19-24 days in British Columbia and extends from 10 May to 22 September, with 51% of nestling records being between 26 June and 30 July (Campbell et al. 2010). and T. Szép.

Direct evidence for trans-Caribbean migratory flights of swallows and dragonflies. In Europe, Barn Swallows are responding to climate change by nesting earlier due to warmer temperatures in spring (Møller 2008). Is there an [observed, inferred, or projected] continuing decline in number of locations? Little information on the effect of parasites is available for North America, nor is there any information as to whether rates or severity of infestations has been increasing. Rosenberg, C.M.

Thanks to Mike Cadman and Becky Stewart for granting permission to reproduce maps from the Ontario and Maritimes breeding bird atlas projects, and to Andrew Couturier for technical assistance in their reproduction. Eckert, and N.L. Despite these losses, both the current distribution and abundance of the Barn Swallow in Canada (and North America) are still greater than they were before European settlement created large amounts of artificial nesting habitat and foraging opportunities that were readily exploited by the species. Extirpated (XT) A wildlife species no longer existing in the wild in Canada, but occurring elsewhere. Rosenberg, A.O. A comparison of the Barn Swallow’s probability of occurrence in Ontario between the first (1981-1985) and second (2001-2005) atlas periods shows an overall significant decline of 35% (Cadman et al. 2010). 1997), but takes less time if old nests are reoccupied and repaired (Brown and Brown 1999a). Nestlings are, however, frequently exposed to high rates of ectoparasitism (mites, fleas, feather lice, blowflies), which can limit productivity. For example, in the St. Lawrence Lowlands of Quebec, the number of dairy farms fell by half from 1971 to 1988 due to farm abandonment, industrialization and urbanization (Jobin et al. Lohoefener, R.R. Breeding pairs form each spring after arrival on the breeding grounds. 595 pp. Elle fait son nid, couve et nourrit ses petits Threats are not well understood, but are thought to include: COSEWIC HistoryThe Committee on the Status of Endangered Wildlife in Canada (COSEWIC) was created in 1977 as a result of a recommendation at the Federal-Provincial Wildlife Conference held in 1976.

The above abundance estimates are based on BBS count data from the mid-1990s; the current species’ abundance in Canada is about 55% lower when declines that have occurred since then are taken into account (see Fluctuations and trends). 1999. [accessed November 2009]. Barn Swallows are diurnal, long-distance migrants that winter in Central and South America (Brown and Brown 1999a). Patterns of spring arrival dates differ in two hirundines. Loss of Barn Swallow foraging habitat has also occurred in Ontario (Cadman et al. This report was overseen and edited by Jon McCracken, Co-chair of the COSEWIC Birds Specialist Subcommittee. The causes of the recent Barn Swallow declines, and indeed of those for many other aerial insectivore birds in Canada, are recent and poorly understood (Nebel et al. While there have been losses in the amount of some important types of artificial nest sites (e.g., open barns) and in the amount of foraging habitat in open agricultural areas in some parts of Canada, the causes of the recent population decline are not well understood.

In Canada, it is identified as being ‘Secure’ in six provinces/territories and as ‘Sensitive’ in six (Canadian Endangered Species Conservation Council 2006; Table 4). NatureServe. 1983. In the 1800s and early 1900s, there was a significant increase in the amount of suitable anthropogenic habitat for Barn Swallows, especially in eastern North America. Møller. More studies are needed to test this hypothesis, and particularly how it might be operating across the Barn Swallow’s range. 1997), but generally average no more than 10 nests (n = 161 colonies; Peck and James 1987). Catalogue No. An index of area of occupancy (IAO) in Canada based upon the 2x2 km grid cell method cannot be calculated at this time, because coordinates of the vast number of nesting sites are impossible to map. Adults display a high-degree of fidelity to nest sites (Brown and Brown 1999a). 1999. Not only has the level of this threat been diminishing over time, its timing does not overlap with the onset of recent decline in Barn Swallow populations. 2006). The Canadian Wildlife Service, Environment Canada, provides full administrative and financial support to the COSEWIC Secretariat. The global population of Barn Swallows in the 1990s was estimated at 190 million adults (PIF LPED 2007), whereas the North American population was estimated at 51 million adults and the Canadian population at roughly 10.9 million (Table 1). Atlas of the Breeding Birds of Ontario, 2001-2005. In New York, 36% of returning birds used the same nests from the previous year (Shields 1984). Colonial breeding in the Barn Swallow (Hirundo rustica) and its adaptive significance. Designations are made on native species for the following taxonomic groups: mammals, birds, reptiles, amphibians, fishes, arthropods, molluscs, vascular plants, mosses, and lichens. There is no doubt that they occur widely on public lands that are protected as federal and provincial protected areas, such as national parks (the Barn Swallow is present in at least 44 protected areas managed by Parks Canada; Parks Canada 2009), Migratory Bird Sanctuaries, National Wildlife Areas, and provincial parks.

Indeed, the species persists in relatively “pristine” natural areas in at least some regions of Canada. For example, the Seneca, Cayuga, Onondaga, Oneida and Mohawk are collectively referred to as the Haudenosaunee or ‘People of the Long House’. 2005. 1995. London: Christopher Helm. Winnipeg, Manitoba.

Sparks T. and P. Tryjanowski. While they did find a small decrease in the amount of natural grassland cover (from 24.2 to 23.6% of the landscape), they also found that the area of row cropland decreased, and that the area of planted pasture and hayfield increased from 9 to 16% of the landscape. In southern Canada, adults start to return in the spring by the end of April and the first week of May, but the main influx occurs in mid-May, tailing off in early June (Landry and Bombardier 1996). Kaiser. Federation of Alberta Naturalists. The extent to which declines in the availability of artificial nesting sites is actually limiting the Canadian population is unclear. Will. SARA establishes COSEWIC as an advisory body ensuring that species will continue to be assessed under a rigorous and independent scientific process. Generally, the removal of cattle from pastures causes a decline in aerial invertebrate abundance, which has been reported to be more than twice as abundant over pasture fields compared to cereal fields and silage (Ambrosini et al. Some also practised burning and agriculture, thus creating open landscapes that Barn Swallows would presumably have found attractive. In the last few decades, loss of nesting habitat due to the replacement of older-style wooden farm structures by modern buildings that lack easy access to suitable nesting sites has been cited as a principal reason for recent Barn Swallow declines in North America (Erskine 1992; Campbell et al. In 1978, COSEWIC designated its first species and produced its first list of Canadian species at risk. In Canada, BBS data give the most reliable estimations of the Barn Swallow’s population size and trends. The strength of this survey method lies in the fact that it covers most of the breeding range of the species in Quebec (Cyr and Larivée 1995). 2008). D'autres oiseaux sont également présents, tels le moineau classique (Passer domesticus) et, en été, l'hirondelle vulgaire (Hirundo rustica).
