Journal Title: KULON - Year 2016, Vol 21, Issue
Abstract
In 2015, we noted two cases of the Montagu’s Harrier Cirrus pygargus nesting very close (20m and 23m) to farm buildings in the agricultural landscape of the Mazovian Lowland. In the locality Olszewo-Grzymki, a nest was found containing a small nestling and four eggs, which was located in a 1-ha triticale crop field at a distance of 23 m from the nearest farm building. On the next visit, the nest was already abandoned. The second case took place near the locality Ukazy. The nest was placed in a triticale crop field at a distance of 20 m from the farm fence. The pair raised one chick. In the Mazovian Lowland at the end of the 1990s nests were located 150-200 m from farms, but during the recent 10-years the nests have been frequently discovered at a distance of 70-150 m.
