Between 19th July and 1st August 1997, at the Chany Lakes in southwestern Siberia, data were collected on phenotype features and behaviour of the local populations of gulls Larus belonging to the taxonomically vague form barabensis.These were compared with data from the literature and museum material on the morphological, oological and behavioural characters of L. c. cachinnans and L. (fuscus?) heuglini, as well as those of some other related gull forms.
