The yellow-legged gull (Larus michahellis) breeds along the shores of Israel. Its largest breeding colonies are on Nachlieli Island at Rosh Hanikra, Pigeons Island at Maagan Michael, and in our Zoological Garden.

Since 2010, Amir Ben Dov has been studying the gulls in the Garden, their breeding extent and success. The study employs large and conspicuous leg rings that enable the individual identification of each gull from a great distance.

The chicks that were hatched this year on our lawn were ringed in mid-May and the beginning of June. This year saw a peak number of incubations (19) but not a peak number of chicks, as survival rates were not particularly high.
This year, as in previous years, several yellow-legged gulls nested in the Maoz Aviv neighborhood in Tel Aviv. One of the males that bred there this year was ringed four years ago as a fledgling in the Zoological Garden and today is a father of three! According to Amir, we can now, for the first time, start making a sort of family tree.
