Justification of Red List category
This species has a very 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 is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size may be moderately small to large, but it is not believed to 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 40,000 mature individuals, equating to 60,000 individuals (Wetlands International 2020).

Trend justification
The current population trend is not known (Partners in Flight 2019, Wetlands International 2020).

The Yellow-footed Gull is primarily found in the Gulf of California (Mexico) and rarely in southern California (U.S.A.), with some post-breeding dispersal north to the Salton Sea and south to Sonora (del Hoyo et al. 1996).

This species is found on sandy and rocky islands usually with little or no vegetation. Its diet includes fish, invertebrates, carcasses or marine mammals and offal. It can also take small seabirds and pelican eggs. Egg-laying begins in early April in colonies mostly under 100 pairs (del Hoyo et al. 1996).

At present there are no factors known to pose a genuine threat to this species.
