    Conservation DecliningThere is little information on Short-billed Dowitcher population trends. A 2012 study found no updated information, and so the latest population estimate is from 2006. At that time the North American breeding population was estimated to be 153,000 birds. After declines in the 1990s and 2000s, it appears that numbers are now similar to counts done in the 1980s. Three subspecies of Short-billed Dowitcher breed in North America. Overall, central and eastern populations appear stable, with the exception of ongoing declines since the 1970s in Ontario. It is not clear what population trends are in western populations. Short-billed Dowitcher is on the 2014 State of the Birds Watch List, which lists bird species that are at risk of becoming threatened or endangered without conservation action. Back to top
