Abstract
In 2014, a total of 1883 nests were recorded in occupied colonies of the Rook Corvus frugilegus on an area of 1219 km2 of the Węgrów county. Rooks nested at 25 sites containing from 1 to 280 nests, with a mean density of 150.4 nests/100 km2. This density was lower than in the neighboring Sokołów county in 2014, and a little higher than in the Siedlce county in 2012.
