(2014) confirmed that Streaked Horned Lark is well-differentiated from other subspecies. 1997). Each of the three clades was supported by bootstrap values ≥86%. The larks, or Alaudidae (pronounced ah-LAU-dih-dee), are composed of ninety-seven species in twenty-one genera found mostly in Eurasia and Africa. © 2020 All Rights Reserved. The historical extent of occurrence (EOO) in Canada stretched from Campbell River south to Victoria and east to Chilliwack, an area of about 15,000 km2. While airports are known to provide some of the last habitat refuge for grassland species, including Horned Larks, mowing and other activities at airports during breeding disturbs larks and can cause nest destruction or abandonment, even with modified mowing regimes (Wolf and Anderson 2014). 2001. Scientific name: Eremophila alpestris strigata. Environment and Climate Change Canada, Ottawa, Ontario. McNichol, M., pers.

Boyd (ed.). : "http://www. This low fecundity was the result of low egg hatchability and fledging success, high clutch depredation, and long intervals between failed nests and re-nests. However, this population consists of only about 150 pairs. 1997. 1942. Washington Department of Fish and Wildlife, Olympia, Washington. Campbell et al. For Horned Larks at our study site, the incubation period lasts around 11 days. Global range. A clutch of four eggs is typical, although two to seven eggs are possible (Baicich and Harrison 1997). Map of the current and historical breeding distribution of the Streaked Horned Lark in the Pacific coastal plains of southwestern British Columbia, Washington, and Oregon. The birds of Canada, revised edition. Streaked horned lark. Cooper, J.M., pers. 1997; Cooper pers. 2016. Preferred habitats include plains, fields, airports, and beaches. This information is used to ensure that we give you the best experience on our website. Among the breeders, Streaked Horned Lark (E. a. strigata) has the most restricted distribution (Campbell et al. The 2016 Partners in Flight Landbird Conservation Plan classifies the Horned Lark as a "Common Bird in Steep Decline." Gotz, M., pers. The horned lark breeds across much of North America from the high Arctic south to the Isthmus of Tehuantepec, northernmost Europe and Asia and in the mountains of southeast Europe. 2011. : "http://www. Slate Creek Press, Bolinas, California. Volume 3: Passerines. xi + 29 pp. It is unlikely to be a source of dispersing birds to re-establish a breeding population in British Columbia. Low fecundity is believed to be the result of low egg hatchability and fledging success, high clutch depredation, and long intervals between failed nests and re-nests. pageTracker._trackPageview(); Belly, undertail coverts, chest, flanks, and foreneck. Elsewhere, prairie habitat in western Washington has declined 98% since the arrival of European settlers, with prairies being converted to urban or unsuitable agricultural areas, returning to forest because of fire suppression, or being invaded by exotic plants (Smith et al. Owner, Cooper, Beauchesne and Associates, Qualicum Beach, British Columbia. In the Fraser Valley, patches of suitable habitat in agricultural land may now be too small to support Streaked Horned Lark, so the potential breeding range is likely limited to sparsely vegetated coastal dune and meadow habitats elsewhere in the Lower Mainland and southeastern Vancouver Island areas (Environment and Climate Change Canada 2016). Photo Credit: Madeline Aberg. The Horned Lark is widely distributed in North America, breeding throughout the United States and Canada except in the southeastern United States and in boreal forests. The soils of these prairies are thin, have low nutrient levels, and drain rapidly – characteristics that help maintain a prairie grassland condition. comm. These birds return to their birthplace after every migration (a characteristic known as philopatric). This report may be cited as follows: COSEWIC. 1998) and 95% or more (Fuchs 2001; MacDougall et al. Streaked Horned Lark in Canada has been historically restricted to southwestern British Columbia (Godfrey 1986; Campbell et al. The current range of the streaked horned lark can be divided in to three regions: (1) the Puget lowlands in Washington, (2) the Washington coast and northern Oregon coast, and the lower Columbia River (including islands and dredge spoil deposition sites west of Portland, Oregon), and (3) the Willamette Valley in Oregon. 2014. Although Streaked Horned Lark habitat was never large in extent, suitable habitat has been in decline over the last few decades. Committee on the Status of Endangered Wildlife in Canada. They sampled 32 individuals and compared them to 68 Horned Larks from Alaska, alpine and eastern Washington, Oregon, California, and Asia. Criterion E (Quantitative Analysis): Analysis not conducted. Journal of Field Ornithology 83:315-322. It was listed as Endangered under the federal Species at Risk Act in 2005 (Environment and Climate Change Canada 2016) and Threatened under the US federal Endangered Species Act (2016).

BIRD OF THE WEEK: September 29, 2017 SCIENTIFIC NAME: Eremophila alpestris POPULATION: 97 million TREND: Decreasing HABITAT: Open, sparsely-vegetated habitats (including prairie, desert, shore, and tundra) across several continents, Horned Lark range in North America, NatureServe. Pearson. Environment and Climate Change Canada. The historical breeding distribution of Streaked Horned Lark is restricted to the coastal lowlands of southern British Columbia, Washington and Oregon (Beason 1995; Figure 1). The female incubates. Boise State University, Corner of Capitol Boulevard and University Drive, Morley Nelson Snake River Birds of Prey National Conservation Area in southwest Idaho, negative impact on birds and other wildlife. (2011) is 0.91 ± 0.17 female fledglings/female/year (n = 4 years; 95% CIs 0.63, 1.19). comm. Munro, J.A., and I. McT. 1997. Pearson, S.F., M. Hopey, W.D. In fact, potential mates seem prone to confusion on this score: a male catching a glimpse of a dust-bathing female may attempt to mate with her. var sc_security="340ce72a"; This area could contain suitable habitat, but only if fields are mowed short prior to the nesting season (i.e., when mowing will not disturb birds). British Columbia birds typically migrated south to Washington and Oregon for the winter, but a few may have overwintered in British Columbia in some years. Victoria, British Columbia. (2011) documented mean breeding season length in Washington across six sites and 4 years: breeding season length (days) was 94.0 ± 10.5. 1993. 1997; Rogers 2000; Stinson 2005). American Midland Naturalist 136:358-366. One of the last known summer occurrences was 10 birds seen on 1 May 1987 (Campbell et al. As a regional rarity, it is sought by birders and sightings tend to be recorded in eBird and BCVIBird Yahoo Group (which functions as a rare bird alert on Vancouver Island and the Lower Mainland); such local observations are generally credible for this taxon because to be publicly posted in eBird, rare bird sightings must be documented and verified. Beauchesne, S.M. "https://ssl." She is currently a member of the COSEWIC Birds SSC, and a daily contributor to eBird. Horned Larks will also form mixed flocks with other species such as longspurs and buntings (Beason 1995). 2014. However, the subspecies breeds in Washington State and small patches of potentially suitable habitat remain on Vancouver Island and in the lower Fraser River Valley in British Columbia, although these continue to decline in both extent and quality. They forage on the ground year-round, walking or running in erratic patterns as they glean seeds and pursue small insects.
