uk – ukr – Українська – Ukrainian | About 40 million speakers in Ukraine, Russia and some other East European countries | Avionary Species Coverage >99% | The Ukrainian names are those of the book ‘Vitchyzniana nomenklatura ptakhiv svitu’ (2018) of Hennady V. Fesenko of the Zahidnoukraïns’ke Ornitologičke Tovarystvo (West-Ukrainian Ornithological Society). Further names, especially recent and potential splits, were elaborated through fruitful personal communication with Mr. Fesenko. Ukrainian names were originally provided by Igor Gorban of Lviv State University, who sadly passed away in 2017. Ukrainian consistently uses two-word names for species (exceptionally one-word names for one-species families), and three-word names for subspecies. The Ukrainian names are also listed on the relevant species list G, together with Russian, Belarusian and Turkish: la/uk/be/ru/tr.
