Conservative estimate, with help from the photos. There was a very big group, shown in its entirety in the last photo, and whose subgroups are shown in the other group photos, except the penultimate (which shows a second, separate group). The closeup photos (shown first) are of birds in a third smaller group of 15 gulls. I counted the birds using zoom on the photos, in groups of 10, sometimes 5 when possible, leaving birds out of the count when in doubt. The big group has, from my gross (but conservative) counting, 700+ birds. The second group has 100+ birds. Joining these 2 groups (ignoring the third smaller one), there is a bare minimum of 800 individuals present. There were also some 20 L. michahellis mixed with the larger group, which I think probably offset with all the birds I left out, but for good measure I will bring the count down to 780, to ensure that I am being properly conservative.
