Oxyura leucocephala (Anatidae: Anseriformes) on the Black Sea coast of the Caucasus

Abstract

New information on the distribution of Oxyura leucocephala on the Black Sea coast of the Caucasus is provided. The first appearance of the species in this region was recorded in 1991. At present Oxyura leucocephala is a small wintering and migratory species found on the Black Sea coast of the Krasnodarsky Krai (Russia) and Abkhazia. Single individuals or pairs of birds are usually noted, less often groups of up to ten white-headed ducks. The most significant was the wintering of Oxyura leucocephala on the lakes of the natural ornithological park in the Imeretinskaya lowland (Sochi, Russia) in 2016-2017. An assumption is being made about the formation of a new wintering area for Oxyura leucocephala occupying the northeastern coast of the Black Sea.

New synonymy and two new species of Caucasian moth flies (Diptera, Psychodidae, Psychodinae) from Azerbaijan and Georgia

“…The Caucasus region, as a biodiversity hotspot, is known especially for its species diversity and endemicity of vertebrates (e.g., Tuniyev 2016;Litvinchuk & Kidov 2018;Tilba et al 2018) andplants (e.g., Efimov 2020;Mursal et al 2020). Entomological activities are relatively rare (e.g., Maslova et al 2020).…”
