| Description | The Common Redshank (Tringa totanus) is one of our most endangered waders. South Moravia is an important area for this species in the Czech Republic. We studied its breeding occurrence there in 2016–2021. Breeding occurrence of the species was found at 117 sites in 2010–2021, at 24 of them Redshanks bred repeatedly. Most localities were found in the Břeclav and Hodonín districts. A temporal field wetland represents the most frequently occupied habitat type (61 %). Breeding sites were located at altitudes of 151–384 m, but most of them were below 200 m above sea level. During the period of systematic monitoring of the species in 2016–2021, the number of breeding Common Redshanks in South Moravia fluctuated between 26–34 and 45–52 pairs. This fluctuation is mainly related to the course of the climatic situation in particular years, specifically to precipitation in the period before breeding, which significantly increases the number of temporal field wetlands. At a site, usually one pair of Common Redshanks bred (69 %), maximally 6–7 pairs bred. Breeding was only proven in 13 % of pairs, which is related to the mapping methodology, but probably also due to low breeding success. The incubation started from the end of March to the end of May with a maximum in the first half of May, which indicates more replacement clutches. The main causes of the threat are discussed in the article and the possibilities for protecting the species in our country are described. |
