Gulls

[Aimee Cokayne]

Hi All,

Is this Heuglin's and a group of Slenderbills?

Thanks

Hi Aimee

Your small gulls are mostly Slender-billed, but there are at least a couple of Black-heads in there too; one stretching on far left (4th in) is the most obvious example. It is not possible to say for sure what the big gull is - at least, I cannot do it - but I would say possibly not Heuglin's as many of those have rather more extensive dusky trailing edge to the underwing; your bird seems not to have this. Mind you, Steppe Gull ususally shows this to a reasonable degree as well...
