LC
Seaside Sparrow Ammospiza maritima



Justification

Justification of Red List Category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The global population is estimated to number 200,000 mature individuals (Partners in Flight 2020).

Trend justification
The population trend is difficult to determine. Long-term trends from 1970 to 2017 suggest that the population is overall stable (Pardieck et al. 2018). Short-term trends report a population increase over the past ten years, but are subject to a large uncertainty (Pardieck et al. 2018). Precautionarily, the species is here assessed as stable.

Distribution and population

Ammospiza maritima is endemic to south-eastern U.S.A., occasionally moving into the extreme north-eastern Mexico and south-eastern Canada (del Hoyo et al. 2011). Subspecies nigrescens is extinct, the last record coming from 1980 (Walters 1992).
