Urbanization leads to the biotic homogenization. Some species adapt, others do not tolerate the changes caused by urbanization and disappear. One of the more tolerant species seems to be the Goosander Mergus merganser. In 2019–2023 (during 755 days

The number of records of Acrida ungarica in novel habitats and in places where the species was considered extinct, has markedly increased in recent years. We hypothesized that the newly revealed occurrences, on the northern margin of the species rang

The Western Yellow Wagtail (Motacilla flava) is typical species of agricultural landscapes, where the food supply is significantly limited. The nestling diet composition and its foraging ecology are little known in the entire range. Therefore, we stu

Seasonal differences of bird assemblages were studied using mist-netting method during four seasons (May, July, September, and December) in two years (2014 and 2021) in a secondary wetland habitat (7 mist-nets in willow grove, reed, and scrubland) in

Gryllotalpa gryllotalpa is widely distributed in the lowlands and hilly regions of southern, western, eastern Slovakia, outside the mountains as the High and Low Tatras. It was found at 516 sites, including 136 sites (5.3% of 2,561 studied sites) whi

Urbanization changes natural environments by transforming the landscape and reducing local biodiversity. However, some urban areas with heterogenous habitats can represent a supplementary breeding environment for non-urban birds. Successful and unusu

Breeding and breeding density was studied in the Short-toed Treecreeper (Certhia brachydactyla) in two sites (riparian forest and park habitat) in Western Slovakia in 2015–2020. The breeding density was 3–5 nests (mean 4.2, i.e. 2.63 nests/10 ha,

Abstract Reproductive interference can shape regional distribution patterns in closely related species, if prezygotic isolation barriers are weak. The study of such interaction could be more challenging in nuptial gift‐giving species due to the dir

During 2013–2017, assemblages of bush-crickets and grasshoppers were surveyed in two neighbouring flysch mountains – Čergov Mts (48 sites) and Levočské vrchy Mts (62 sites) – in northern part of Western Carpathians. Species were sampled most
