The Whimbrel migrates in long bouts from its arctic breeding grounds to its South American wintering grounds. Exact migratory routes are becoming better understood through the use of bird-borne data loggers (e.g., Watts et al. 2008). Results from migration monitoring surveys suggest that the population has changed little relative to about 1970. However, many birds may overfly the areas with the greatest coverage of migration monitoring surveys, so this assessment of the species' status is tentative. This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.

Conservation and management

Populations were greatly reduced by market hunting in the late 19th and early 20th century (Skeel and Mallory 1996). The species is still hunted in the Caribbean and South America, but current estimates of harvest are lacking for most regions. Climate change is expected to have a negative effect on arctic-breeding shorebirds because their conservative life-history strategy (low reproduction and long lifespan) makes it difficult for them to quickly adapt to the effects of accelerated climate change on their breeding habitat (Meltofte et al. 2007). Effects may include: drying of tundra ponds (Smol and Douglas 2007, Stow et al. 2004), shrub encroachment (Tape and Racine 2006, Callaghan et al. 2005), asynchrony of insect-chick hatch (Tulp and Schekkerman 2008) and unusual weather events (Tulp and Schekkerman 2006, Martin and Wiebe 2004).

 

Bird conservation region strategies

Environment and Climate Change Canada and partners have developed Bird Conservation Region Strategies in each of Canada’s Bird Conservation Regions (BCRs). In these strategies, selected species are identified as priorities for one or more of the following reasons:

  • conservation concerns (i.e., species vulnerable due to population size, distribution, population trend, abundance, or threats)
  • stewardship responsibilities (i.e., species that typify the regional avifauna or have a large proportion of their range or population in the sub-region)
  • management concerns (i.e., species that require ongoing management because of their socio-economic importance as game species, or because of their impacts on other species or habitats)
  • other concerns (i.e., species deemed a priority by regional experts for other reasons than those listed above or because they are listed as species at risk or concern at the provincial level)
