Mongolian Short-toed Lark Calandrella dukhunensis, an overlooked East Asian species
2021
Alström, Per | Gombobaatar, Su̇ndėviĭn
The eastern subspecies of Greater Short-toed Lark Calandrella brachydactyla dukhunensis has recently been considered a separate species, Calandrella dukhunensis, by several authors based on molecular data. We present supporting evidence for this treatment based on studies of morphology, vocalisations and song-flight, and also present new data on other aspects of its biology based on field studies. We show that its breeding distribution is considerably smaller than previously thought, and is restricted to the eastern half of Mongolia and, marginally, neighbouring parts of China and perhaps Russia.
