LC
Eastern Yellow Wagtail Motacilla tschutschensis



Justification

Justification of Red List category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but it is assumed to be relatively common within its large range. It is here tentatively placed in the band 50-150 million mature individuals.

Trend justification
In Europe, trends since 1980 show that populations have undergone a moderate decline, based on provisional data for 21 countries from the Pan-European Common Bird Monitoring Scheme (EBCC/RSPB/BirdLife/Statistics Netherlands; P. Vorisek in litt. 2008).

Distribution and population

Motacilla tschutschensis occurs from Siberia and Transbaikalia south to Mongolia and Manchuria, east to Amurland, Ussuriland, Sakhalin, Kamchatka, northern Kurils and Commander islands, and possibly Pribilofs and Aleutian islands, south to northern Japan (northern Hokkaido), as well as extreme northwestern North America (northern and western Alaska, extreme northwestern Canada). The species winters in southeastern Asia (Myanmar and Thailand east to Maly Peninsular, southeastern China and Taiwan, China), perhaps west to India and east to the Philippines, south to Indonesia, Sundas and Wallacea, and northern Australia.
