| Popis | Temporary field wetlands, which occur periodically after heavy rainfall, are overlooked habitats hosting interesting communities of plants and animals in an otherwise homogenous agricultural landscape. Wetland birds are an important group inhabiting these habitats. We studied 84 field wetlands of this type in South Moravia to find out what bird species occur there and how they use them. We collected data on the occurrence of wetland birds at these sites in 2010–2021, including data from the faunistic database of Czech Society for Ornithology (http://birds.cz/avif ). In total, we found 98 species. Most were shorebirds (Charadriiformes; 38 species), followed by waterfowl (Anseriformes; 21 species), wetland songbirds (Passeriformes; 17 species) and Pelecaniformes (9 species). 41 species are protected in the Czech Republic. 2–65 species with an average of 17 species were recorded at particular sites. We found a positive effect of the site area and the number of years in which the site was flooded on the number of recorded species, while the effect of altitude or the district in which the site was located was not found. Particular species used field wetlands as breeding grounds, feeding habitats, migration stopovers or wintering grounds. Among the breeding species, the most important were the Northern Lapwing (Vanellus vanellus), the Common Redshank (Tringa totanus), the Mallard (Anas platyrhynchos), the Little Ringed Plover (Charadrius dubius), the Common Snipe (Gallinago gallinago), the White Wagtail (Motacilla alba), the Western Yellow Wagtail (Motacilla flava) and the Western Marsh Harrier (Circus aeruginosus). Among the non-breeding species, the most frequent were the Green Sandpiper (Tringa ochropus), the Grey Heron (Ardea cinerea), the Ruff (Philomachus pugnax) and the Wood Sandpiper (Tringa glareola). The Jack Snipe (Lymnocryptes minimus) was the most important wintering species. Due to the absence of territorial protection, there are limited possibilities for the conservation of temporal field wetlands. This should be primarily based on the adjustment of agricultural management to enable the creation and maintenance of an aquatic phase of field wetlands, including the breeding of important bird species in their vicinity. The large number of wetland bird species found on the South Moravian temporal field wetlands proves their great biological and conservation value. At the same time, these habitats are still overlooked, which is why we would like to motivate other ornithologists, conservationists and nature lovers to pay attention to these valuable habitats and support their protection. |
