Abstract
In 1974-1975, a breeding bird survey with the cartographic method was carried out on 5 sample sites covering in total 49.8 ha of open or willow-overgrown sedge fens of Carex elata and alder-birch forest on fish ponds near Siedlce. 43 breeding bird species were recorded that included from 11 to 17 species in sedges and 32 species in forest. The density of the whole community ranged from 379 to 98.3 ( x = 62.0) pairs/10 ha. Dominant species, comprising over 5%, were: Sedge Warbler Acrocephalus schoenobaenus, Common Reed Bunting Schoeniclus schoeniclus, Mallard Anas platyrhynchos, Eurasian Coot Fulica atra and Eurasian Reed Warbler Acrocephalus scirpaceus. Average density of birds typical of flooded sedges and willow shrubs was equal to 38.0 pairs/10 ha, waterbirds – 10.4, and forest and coppice species – 8.4 pairs/10 ha. Two other groups distinguished according to their habitat preferences (meadow birds and birds of semi-open farmland habitats) were recorded in low numbers (on average 1.4-3.7 pairs/10 ha). The study sites re# ected vegetation succession from open sedge fens, with only a limited number of willow shrubs, where meadow species occurred (Northern Lapwing Vanellus vanellus, Whinchat Saxicola rubetra, Common Snipe Gallinago gallinago), through flooded sedges considerably or totally overgrown with willows, where numerous waterbirds and reed birds were recorded, to dense alder-birch forest and bird species typical of woodland and coppice. A significant influence of water level on the density of some waterbird species, and to a lesser degree on reed birds was documented. Flooded and willow- overgrown sedges on fish ponds were important breeding habitat for many species of waterbirds and reed birds, including rare and endangered species, like the Eurasian Bittern Botaurus stellaris and Little Bittern Ixobrychus minutus.
