I dont't know if dwarf desease can exist in birds but how can you explain this (apparently) pygmy juvenile Black-headed Gull ?
The individual is in direct comparison with other Black-headed Gulls so there is no trick behind.

We feel confident to rule out Bonaparte's Gull and Little Gull but not some kinds of hybrid forms between BHG and LG (if they exist in nature).

Do you have any other explanation?

Thanks for help
Luciano

I have seen a small BHG - though not as tiny as yours.

I was doing all I could to claim a Bonaparte's Gull!

I don't know how common it is.

I once seen dwarf Vervet Scoter which took me much effort to identify!

Coincidentally, I also saw a very small BHG at Chard Reservoir the other day. Nothin on it to suggest anything other than BHG, except that it was nearly two inches shorter in height than the bird next to it.

Sometimes you do see small BHG and on rare occasions even with black bills.
However with a spread wing and a look like this:

the will sooner or later reveal themselfs as BHG like the one above.
