Abstract:
Northern Kazakhstan and adjoining areas of Russia have vitally important autumn staging sites for arctic breeding geese, especially for the globally threatened Lesser White-fronted Goose Anser erythropus (LWfG) and Red-breasted Goose Branta ruficollis (RbG). Part of the Fennoscandian and the entire Western Main subpopulations of LWfG and the global population of RbGs are believed to stage there, which facilitates obtaining up-to-date population estimates for these species. A total of 80 lakes were surveyed across four survey areas in autumn 2016, recording more than 1.2 million geese in the region. Greater White-fronted Geese Anser albifrons (GWfG) were the most abundant with an estimated c. 890,000 birds, with counts of c. 250,000 Greylag Geese Anser anser, c. 53,000 Ruddy Shelduck Tadorna ferruginea, c. 39,100 RbG and c. 32,000 LWfG also recorded during the surveys. Based on a priori lake classification for both LWfG and RbG, to stratify survey lakes in order to generate total population estimates, survey teams visited a sample of different lake types. After removing lakes smaller than the observed minimum lake size used by each species, the total number of potential lakes available within the core staging areas of each species (335 lakes of > 320 ha for LWfG; 361 lakes of > 100 ha for RbG) was calculated. Bootstrapping procedures, with replacement, were then used to estimate the total numbers likely to be present in the region. These calculations produced total estimates of 34,250 birds (95% confidence intervals = 28,500–40,100 birds) for the Western Main population of LWfG (well in excess of current population estimates of 8,000–13,000 individuals) and an estimated population of 50,100 RbG (95% CI = 28,100–72,600 birds), broadly similar to recent population estimates of 55,000–57,000. We recommend that future surveys continue to monitor as large a region and as many lakes as possible in order to capture inter-annual variation in the distribution of birds and to provide more reliable assessments of population size and trends of these migratory species.

Abstract:
In Russia, the conservation of anseriformes is possible through the creation of temporary huntingfree zones during hunting season, especially in spring. A justification for creating such zones and outlining their boundaries (by analogy with the experience derived from the countries on North America) each season must be based on data on annual waterfowl monitoring. The present paper describes census experience drawn from the use of ultralight aviation for further delineating the key staging sites of waterfowl in western Siberia. To refine the duration of monitoring, observation data were combined with those derived from geese equipped with GSM-GPS transmitters. In the spring and autumn of 2012–2014, we covered over 50000 km of aerial surveys of 25 waterfowl species. A new method is advanced for assessing their numbers based on visual observations, flock photography, and modern statistics. We estimated the species densities in 16 habitat types delineated on the basis of Landsat imagery. In terms of this, a system is proposed for extrapolating the survey data on 25 waterfowl species onto model sites in western Siberia. Drops in the numbers of several mass game species were noted. Based on an evaluation of the habitat quality, ten waterfowl hunting-free zones were suggested and delineated. A GIS project was launched that incorporated the main migration routes, boundaries of the key sites, places of mass bird aggregations, and sites for the observation of rare, Red Data Book. A program of long-term monitoring and sustainable use of waterfowl in the study region is offered. Such an approach must also be applied to other regions of Russia.

Abstract:
The purpose is to investigate the area which the moulting lesser white-fronted goose, Anser erythropus, visits while it stays at the lake Lillfjärden in Hudiksvall, Sweden, during the summers. The lake Lillfjärden is unique due to the high amount of other different species of birds, visiting it, and the fact that the lesser white-fronted goose visit it makes it even more extraordinary. Which components affects the lesser white-fronted goose´s choice of place to conduct itself round the lake, and which components affects it to keep away from other places? The abiotic components to be considered is sunlight, amount of wind and the areas topography. The biotic components to be considered is producers, consumers, and both human settlements and human presence. Put the coordinates from three moulting lesser white-fronted geese, during a period in the summer, into Microsoft Excel. Further on, use the “3D-maps”-function and make three maps representing each one of the birds and one map with all three of them. From these results chose three places of where the birds have been most of the time and then two places which the birds have kept away from. Investigate these areas, from the biotic and abiotic components, in real life and write down the result in a table. Conclusions from the result could been drawn that show slightly that the lesser white-fronted geese preferred areas with evening-sunlight and ground plenty with solid food as grass and herbs. Components which the geese kept away from had the similarities that they had small grounds with grass, they were close to human activity and close to an inflow and outflow of a small river by the lake. The conclusions are built foremost by assumptions in the observations that have been made in the five selected areas round Lillfjärden. The amount of areas that have been observed are for the credibility of this study not enough, improvements can be done in future studies. Improvements such as increasing the quantity of studied geese, more scientific methods and change of time for the observations of the environments, from winter to the moulting-period in the summer.
