Long-billed dowitcher (Limnodromus scolopaceus Say, 1823) in the Asian part of Russia: area and chronology of the meetings in the Baikal Siberia

Long-billed Dowitcher (Limnodromus scolopaceus) is a migratory breeding species of the North-East of the tundra zone of Russia, distributed from the Anabara river valley the East to the Eastern extremity of the Chukotsky Peninsula and the Anadyr river basin, Islands Ayon and Wrangel [Stishov et all., 1989; Stepanyan, 1991, 2003; Koblin et al., 2006]. The ecology of the species within the breeding area is relatively well-represented in the special ecological and faunistic monographs [Kistchinski, 1988; Labutin et al., 1988; Kretchmar et al., 1991, etc.]. Non-breeding Dowitcher, according to the latest data [Romanov, 2013], are found on the Putoran Plateau, Kolyma and Koryak uplands, in the mountains of Yakutia.

In Baikal Siberia this species belongs to the causal [Yelayev, 2005, 2013, 2016]. This status is based on a some finds during autumn migration. So, solitary Dowitcher was shot on 22.09.1987 on the Western shore of the Middle Baikal in the Maloe More area; it is saved in the Zoological Museum of Irkutsk State University [Pyzhyanov, 1989; Pyzhyanov et all., 1998]. Yu. I. Melnikov (1998) writes about the findings of causal exemplars in the neighboring Baikal Lake basin areas, in particular in the Bratsk reservoir and Northern Mongolia. The author with two Italian birdwatchers — Gian-leonardo Allasia and Enrike Garofanini — observed a flock of at least 12 ind. of Black-tailed Godwits (Limosa limosa) feeding in the coastal shoals in the Posol’sk village on the southern Baikal Lake and 2 ind. of Long-billed Dowitcher 13.08.2016.
