Population justification: This species is widespread and very commonly observed. The global population is estimated to number 2,300,000 mature individuals (Partners in Flight 2023).
Trend justification:
A reduction of 22.0% (-26.9 to -18.0%) within three generations was estimated in the Avian Conservation Assessment Database December 2023 update (Partners in Flight 2023) based on modelled Breeding Bird Survey data. This species is abundant and commonly observed and this trend is considered well-supported. The above rate of decline is supported by an analysis of eBird trend data which estimated a three-generation reduction of 18.3% (-22.8 to -14.3%) (Fink et al. 2023).
Data from the North American Breeding Bird Survey and Christmas Bird Count indicate declines of c.19% and c.13% respectively in the three-generation period 2008-2021, with no indication the rate is slowing (Meehan et al. 2022, Ziolkowski Jr. et al. 2022). The Central American Waterbird Census found a moderate decrease (-16%) over the period 2012–2020 during the winter period in southern Mexico and Central America (van Dort et al. 2023). Although low, numbers wintering at Tomales Bay in California are declining and are thought to reflect population decreases elsewhere in the west (Warnock et al. 2021).
A recent analysis of migration count data at stopover locations throughout North America (Smith et al. 2023) also indicates declines, though only covers part of the population. A reduction of 37.0% was estimated over three generations, albeit within a wide confidence band of -63.8% to -1.1%.
Overall, based on data sources that cover most of the species’ range, a reduction exceeding 20% in three generations is estimated. Uncertainty over the future rate of decline means that a value for the future three generations is not determined.
