Trends

Trends

Moderate increase (low reliability) based off shorebird migration monitoring which has low precision because coverage is heavily on coastal sites and BASA migrate mainly through central N.A. where coverage is low (Status of Birds in Canada 2014 update, unpublished data provided by H306); Long term trend (42 years) uncertain, but thought to be increasing or stable (see Rosenberg et al 2019 supplemental info S1:Median: + 73 534 individuals, lower CI: -21, 388 individuals, upper Cl: +338, 993 individuals)
