warning Near Threatened
NT (D1)

The Yellow-legged Gull is classified as Near Threatened (NT) because of its small population size (about 80 mature individuals), combined with a regional adjustment for the fact that its population is expanding and that the Israeli population has always been a marginal population at the edge of its global range. In the previous edition of the Red Book (2002), it was classified as Critically Endangered (CR). The improvement in the threat category reflects the population growth and its expansion to central Israel, in particular to the Tel-Aviv Metropolitan Area.

The Yellow-legged Gull is a resident breeding species found in small numbers on the northern Coastal Plain, in areas with fishponds and reservoirs close to the coast, and on small islands in the sea. In recent years the species began nesting in the Tel-Aviv Metropolitan Area as well. The estimated population in the different areas: 10-20 pairs on the Rosh HaNikra-Acre coast, 10-12 pairs on the Carmel coast, about 10 pairs in Tel-Aviv and 1-3 pairs in Yavne and Ashdod.
First nesting discovered in 1951. In the 1970s and 1980s, 5-12 pairs nested on the islands opposite Rosh HaNikra and between Atlit and Ma’agan Michael (Paz 1986, Shirihai 1996).

Occupancy 1990-2020

The map shows differences in the species breeding distribution between the 1980's breeding map and the current weighted breeding evaluation. Negative value - species previously bred in the grid and is not presently breeding; positive value - species has not previously bred in the grid and is currently breeding.

Change in Relative Abundance 1990-2020

The map shows the changes in the relative abundance of a species in each of the distribution grids between the breeding map of the 1980s and the weighted current breeding evaluation. Negative values - decline in abundance; positive values - increase in abundance; zero - no change in abundance.
