Abstract:

Migratory birds breeding at high latitudes face challenges in relation to timing of breeding vs. annual weather, climate change, and predator abundance. Hunting pressure along migration routes and wintering quarters forms an additional challenge.We studied population structure and interaction with environmental factors in a small population of threatened Lesser White-fronted Geese Anser erythropus, living in sub-arctic zone in Lapland in 1989–1996. Thereafter the population disappeared. The population comprised 2–15 breeding pairs plus 0–12 non-breeders, which left in June to moult elsewhere. 30 broods were observed (0–8 annually) with an average number of 2.9 goslings. Of the 3 satellite tagged plus 7 ringed geese at least 3were shot and altogether 4 killed during the first year. Only 2 were seen alive next year or later. Laying started on average 4 June (21May – 13 June) and hatching took place 2 July (21 June–10 July) with an intra-seasonal clutch size decline. Variation in nesting initiation was not explained by local phenology, but instead by the date of staging peak in the last pre-breeding staging area 600 km south. Reproduction was affected negatively by cold spells and positively by the sum of daily effective temperatures by 5 July. Vole populations were low and a real cycle missing. No effect of reindeer abundance or human presence on reproduction could be found.

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.
