Justification of Red List categoryThis species has a very large geographic range size (extent of occurrence >9 million km
2 in both the breeding and non-breeding seasons), and so does not approach Criterion B thresholds. It also has a large estimated population size (190,000 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 rapid decline of
c. 50%, albeit with interannual fluctuations. Conversely, the Breeding Bird Survey (Ziolkowski
et al. 2022) recorded a
c. 5% increase over the same period, as part of a slow long-term increase. This is mirrored by data from the Christmas Bird Count (Meehan
et al. 2022), which suggest an increase of
c. 17% in the non-breeding population in the southern USA (following a slow long-term increase there, possibly due to short-stopping under climate change). Partners in Flight (2023) infers that the most likely overall trend is a
c. 11% increase. Overall the trend is considered unknown, and the species therefore does not approach Criterion A thresholds. The species therefore continues to warrant listing as Least Concern.
