Abstract:

The global population of Anser erythropus has rapidly declined since the middle of the 20th century. The decline in numbers has been accompanied by the fragmentation of the breeding range and is considered as «continuing affecting all populations, giving rise to fears that the species may go extinct». Overhunting, poaching and habitat loss are considered to be the main threats. The official estimate of the dimension of the decline is in the range of 30% to 49% between 1998 and 2008. Monitoring and the prospection of new areas are needed for the future conservation of this species. The eastern part of the Nenetsky Autonomous Okrug, the Baydaratskaya Bay and the Lower Ob (Dvuobye) are important territories for the Western main population of Anser erythropus on a flyway scale. Moving along the coast to the east, Anser erythropus can stay for a long time on the Barents Sea Coast, from where they fly over the Baydaratskaya Bay to the Dvuobye. We made aerial surveys and identified key sites and the main threats for Anser erythropus on this part of the flyway. According to our data, the numbers of the Western main population of Anser erythropus amount to 48 580 ± 2820 individuals after the breeding season, i.e. higher than the previous estimates made in autumn in Northern Kazakhstan. The key sites of Anser erythropus in this part of the flyway were identified.

Abstract:

For the first time, we estimated the population sizes of two swan species and four goose species from observations during the non-breeding period in East Asia. Based on combined counts from South Korea, Japan and China, we estimated the total abundance of these species as follows: 42,000–47,000 Whooper Swans Cygnus cygnus; 99,000–141,000 Tundra Swans C. columbianus bewickii; 56,000–98,000 Swan Geese Anser cygnoides; 157,000–194,000 Bean Geese A. fabalis; 231,000–283,000 Greater White-fronted Geese A. albifrons; and 14,000–19,000 Lesser White-fronted Geese A. erythropus. While the count data from Korea and Japan provide a good reflection of numbers present, there remain gaps in the coverage in China, which particularly affect the precision of the estimates for Bean, Greater and Lesser White-fronted Geese as well as Tundra Swans. Lack of subspecies distinction of Bean Geese in China until recently also limits our ability to determine the true status of A. f. middendorffii there, but all indications suggest this population numbers around 18,000 individuals and is in need of urgent attention. The small, highly concentrated and declining numbers of Lesser White-fronted Geese give concern for this species, as do the major declines in Greater White-fronted Geese in China (in contrast to numbers in Japan and Korea, considered to be a separate flyway). In the absence of any demographic data, it is impossible to interpret the causes of these changes in abundance. Improved monitoring, including demographic and tracking studies are required to provide the necessary information to retain populations in favourable conservation status.

Abstract:

The mid-winter waterbird counts in Iran were initiated by the Department of the Environment in January 1967. The counts focused on pelicans, flamingos, swans, geese, ducks, cranes and coots, but some counts were also made of other species of waterbirds. By the early 1970s, the counts were sufficiently comprehensive to enable estimations to be made of the total numbers of many species of waterbirds present in Iran in the mid-winter period. The overall results of the counts and these population estimates are presented in a series of tables. It was estimated that in an ‘average’ year in the early 1970s, there were approximately 2,000–2,200 pelicans, 48,000–51,000 flamingos, 380–460 swans, 27,000–32,000 geese, 2.0–2.4 million ducks, 2,300–2,800 cranes and 370,000–410,000 coots wintering in Iran. The number of birds reaching Iran in autumn and remaining throughout the winter was greatly affected by weather conditions both in Iran and in the north Caspian region. In mild winters, large numbers of the hardier species, notably the swans Cygnus spp., remained throughout the winter in the north Caspian, while in extremely severe winters, a large part of the Russian wintering populations moved south into northern Iran. In dry years, when many of the wetlands in Khuzestan, central Fars and Seistan remained dry throughout the winter, large numbers of waterbirds continued on south to winter in the Indian subcontinent or Mesopotamia. In the winter of 1969/70, when conditions were unusually mild in northwestern Iran, large numbers of birds overwintered in the wetlands of the Urumiyeh basin in Azarbaijan, but in most years these wetlands froze over in December, and most birds had left the area by the time of the mid-winter counts.
