Climatic changes may reduce overwinter survival or reproductive potential, while widespread pesticide use may cause decreases in the abundance or diversity of flying insects. Bird-Banding 50:69-70.

Garrison, B.A. Observed percent reduction in total number of mature individuals over the last 10 years. Bank Swallows have a grey-brown head, mantle, rump and wing coverts, contrasting with darker brown remiges and white underparts (see cover photo). Clutch size is typically 3-6 eggs, but averages 5 eggs (Peck and James 1987, Turner and Rose 1989, Campbell et al. Regroupement Québec Oiseaux, Canadian Wildlife Service of Environment Canada, Bird Studies Canada. Black dots depict distributional losses; squares where Bank Swallows were recorded during 1981-1985, but not 2001-2005. The second atlas of breeding birds in New York State. In the operational pit that did not have Bank Swallows, suitable nesting habitat was created late in the breeding season. From 1970 to 2010, the proportion of ÉPOQ checklists including Bank Swallow declined at a rate of −4.4% annually (C.I. 2010. Nest records may be biased toward higher proportions of colonies in artificial sites compared to natural sites, but the level of bias may be similar across Canada. COSEWIC: Designated Threatened in May 2013. In Sweden, large-scale declines in the Bank Swallow population have been associated with changes to gravel and sand pit operations (Lind et al. [accessed 25 July 2011]. Eastern provinces generally have higher conservation status ranks (Table 5). Sixty-three percent of the occupied pits conducted excavation activities that directly destroyed some nesting burrows during the breeding season, amounting to a total loss of 32% of all burrows in the study area (1,762 of 5,868). The Bank Swallow is considered to be among the more evolutionarily basal-branching or “primitive” groups of swallows due to its burrow-excavation habits (Sheldon and Winkler 1993). 270 pp. California Department of Fish and Game: Sacramento, CA., 16 pp. The number of Bank Swallow colonies reported each decade since the 1930s is similar except during the 1970s and 1980s, when the number of colonies reported increased by 2-3 times (Figure 9). These include American Kestrel, Barn Owl (Tyto alba), Belted Kingfisher (Megaceryle alcyon), Northern Rough-winged Swallow, Violet-green Swallow (Tachycineta thalassina), Cliff Swallow (Petrochelidon pyrrhonota), Mountain Bluebird (Sialia currucoides), European Starling (Sturnus vulgaris), and House Sparrow (Passer domesticus) (Hjertaas 1984, Garrison 1999, T. Hoar, pers. Canadian Field Naturalist. Interestingly, the availability of artificial habitats likely increased at the same point available habitat in rivers and streams began to decline (due to dam construction and flood control). However, the population remains in decline. and B.P. Ralph, T.D. This mat is 1-inch thick and 5-inch in diameter to offer support and firmness. Distribution of the Bank Swallow in the western hemisphere. COSEWIC Assessment and Status Report on the Bank Swallow Riparia riparia in Canada, Bank Swallow (Americas) Sand Martin (Eurasia, Africa) Collared Sand Martin (southern Asia), Scientific name: Riparia riparia Linnaeus (1758). In Alberta, Saskatchewan, and Manitoba, the Bank Swallow occurs most commonly across grassland, aspen parkland, and plains ecoregions. vi + 142 pp. Bull, J. Northwest Science 54:210-215. Over large areas of suitable habitat (e.g., Lake Erie bluffs), colonies are nearly continuous and are difficult to demarcate (BSC, unpubl. In 2010, Environment Canada (CWS) conducted burrow count surveys on the Saugeen River (11 km) and in aggegrate pits throughout Wellington County, ON. Figure 9. Population trends in selected species of farmland birds in relation to recent developments in agriculture in the St. Lawrence Valley. The Bank Swallow occurs as far north as the Ungava Peninsula in Quebec (e.g., Kuujjuaq, Umiujaq and Kuujjuaraapik) (Gauthier and Aubry 1996, Quebec Breeding Bird Atlas 2012, M. O’Connor, pers. 1982. 1979. McCracken and P.D. Traditionally, the bank swallows nest in colonies along the streamside banks of North America. 2007. Are there extreme fluctuations in number of locations. ; Celsus sp.) 1997, BSC 2011b). 172 pp. University of Massachusetts, Amherst, 127 pp. No studies of genetic variation in Bank Swallows exist. Eats many flies (including house flies and crane flies), beetles, wasps, winged ants, small bees, and true bugs, plus some dragonflies, stoneflies, moths, caterpillars, and others. The distribution of the Bank Swallow in northern regions of most jurisdictions may be more extensive than described here because survey effort across these vast regions is limited. They mostly eat insects like bees, wasps, ants, butterflies or moths. xviii + 1295 pp. Rimouski, Québec : Regroupement QuébecOiseaux. Males and females have similar annual survival rates (Cowley and Siriwardena 2005). (Trent) on the population dynamics of Semipalmated Plovers. COSEWIC Secretariat c/o Canadian Wildlife Service Environment Canada Ottawa, ON K1A 0H3, Tel. No information exists on the direct impact of climate change on Bank Swallows and thus the following hypotheses are largely speculative. The contributions of many people made this status report as comprehensive and up-to-date as possible.

Initiated in 2010, the Ontario Bank Swallow Research and Monitoring Project is a collaborative effort between Ontario Power Generation, Bird Studies Canada, Environment Canada (CWS), and Beacon Environmental, Ltd. Chart showing the percentage of Bank Swallow colonies recorded in roadcut habitat from the Ontario Nest Record Scheme over the last eight decades. ** Formerly described as “Not In Any Category”, or “No Designation Required.” *** Formerly described as “Indeterminate” from 1994 to 1999 or “ISIBD” (insufficient scientific information on which to base a designation) prior to 1994. The reasons for these declines are not well understood, but are likely driven by the cumulative effects of several threats. Small, compact swallow that is brown above and white below. This may provide a potential explanation for observed population fluctuations on Lake Erie, but it is unclear whether droughts on wintering grounds are a concern for Western Hemisphere Bank Swallows. Whitworth, T.L. Different groups of birds arrive separately where suitable habitat exists, and breeding is synchronized within these areas, thus forming sub-colonies (Petersen 1955, Kuhnen 1985). The greatest distributional changes were observed in the Northern (−52% fewer squares occupied) and Southern Shield regions (−61% fewer squares occupied), despite observer effort being greater in the second atlas period (Cadman et al. GNWT (Government of the Northwest Territories). This doesn’t however mean that there aren’t any factors which might cause a decrease in their number. In 1978, COSEWIC designated its first species and produced its first list of Canadian species at risk. 2007). The Bank Swallow is primarily an aerial forager, consuming mostly flying insects, although sometimes terrestrial/aquatic insects or spiders are taken when locally abundant.
