Chick. The colony is in reeds at a shallow lake in the forest-steppe zone, and is a mixed one. That is, cachinnans and barabensis-type gulls are the two taxa which breed there, at times in mixed pairs and some intermediate types are also present. Here you can have a look at adults from there. Probably heuglini does not breed this far south (tundra breeding species), though few birds were nearly as dark as heuglini (clearly darker than baraba's from SW Siberia). When the chicka are ringed, several alrming adults fly overhead, but it is impossible to tell which is the parents, and therefore which taxon the pullus belongs to. Observations from ringed birds, once they are adult, should confirm taxon.

Shallow lake near Kuznetsk, Penza Oblast, between Moskwa and River Volga.
