Abstract

We reported about several common terns with dark bill (subspecies Sterna hirundo minussensis and S. h. longipennis) in the Lower Ob region of Western Siberia, including nesting of the Central Siberian tern here. The ratio of terns with a dark bill and nominate color was about 8 to 1. Our findings change the previous understanding of areas of the distribution of those subspecies.

Keywords: Area, common tern, distribution, lower Ob, Sterna hirundo minussensis, S. h. longipennis.
