Justification of Red List category

This species has a large geographic range size (extent of occurrence >9 million km² in both the breeding and non-breeding seasons), and so does not approach Criterion B thresholds. It also has a large estimated population size (1,500,000 mature individuals; Partners in Flight 2023), and so does not approach Criteria C or D thresholds. Considering its population trend over three generations (c. 10 years), the data presented in Smith et al. (2023) indicate a small increase of c. 6%, albeit with wide confidence intervals. This is broadly consistent with the c. 14% increase recorded by the Breeding Bird Survey (Ziolkowski et al. 2022). Data from Partners in Flight (2023) suggest that the population may have declined by c. 4%, again with wide confidence intervals. Since the 1980s, declines have been noted at some of the salt lakes where this species congregates on passage, probably associated with drought, but evidence for overall population decrease is inconclusive (Colwell and Jehl 2020). As there is no evidence that the population is declining, it does not approach or meet the thresholds for listing under Criterion A. The species is therefore listed as Least Concern.
