Estimating the autumn staging abundance of migratory goose species in northern Kazakhstan. Wildfowl 68: 44-69.

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.

Keywords: Nakhchivan, Azerbaijan, wintering, Aras reservoir
Abstract:
A field survey of the Aras water reservoir within Nakhchivan Autonomic Republic and the adjoining flood-plain area of the Aras River valley within Sadarak district near the border of Iran and Turkey was carried out i 20-24 January 2015. Only four small flocks of Lesser White-fronted Geese were located, of which the biggest being 80 individuals. However, these observations together with tracking and location data on satellite transmitter tagged birds proves that at least for the LWfG the whole area of the Aras River valley from the border of Turkey to the Aras reservoir dam serves as a wintering ground. Considering their high significance, the wetlands of the Aras reservoir and Sadarak district should be assigned the status of highly protected area. The survey also covered the numbers and distribution of other water bird species in the area. Within Azerbaijan part, more than 25000 waterfowl and shorebirds winters, which qualifies this important area to the list of important RAMSAR wetlands.

Abstract:
Fecal lead (Pb) levels were investigated in the threatened European population of the Lesser White-fronted Goose (LWfG, Anser erythropus) and of the non-threatened Greater White-fronted Goose (GWfG, Anser albifrons) wintering in two wetland areas in northern Greece in order to assess the potential risk from Pb exposure. Fecal, soil and food plant samples were analyzed. Levels of Pb were normalized using Al concentrations in order to sep-arate the effect of possible ingestion of Pb shot from that of soil or sediment accidentally ingested with food. All concentrations are expressed on a dry weight basis. Geometric means of Pb content in the feces of LWfG were 6.24 mg/kg at Evros Delta and 7.34 mg/kg at Lake Kerkini (maximum values of 28.61 mg/kg and 36.68 mg/kg, re-spectively); for fecal samples of GWfG geometric means were 2.39 mg/kg at Evros Delta and 6.90 mg/kg at Kerkini (corresponding maximum values of 25.09 mg/kg and 42.26 mg/kg). Soil Pb was in the range of 5.2–60.2 mg/kg (geometric mean = 22.6 mg/kg) for the Evros Delta and between 13.4 and 64.9 mg/kg (geometric mean = 28.1 mg/kg) for Kerkini. A general linear model fitted to the data showed that Pb levels were very closely dependent on Al levels in the feces from both species and at both sites indicating soil or sediment were the only significant source of Pb; species and site, as well as their interaction, were not statistically significant factors. For both species and at both sites exposure to Pb was evidently very mild and the observed levels of Pb were well below the proposed thresholds for lethal or sublethal effects of Pb poisoning. Soil ingestion appeared to gradually increase from October to De-cember for LWfG at Kerkini, corresponding to a gradual depletion of their food source.

Abstract:
The Lesser White-fronted Goose is a species of conservation concern and considered to be globally threatened with extinction. Since the 1960s, the species has been reported from a total of 22 sites throughout Iran, but in the period 1992–2008, mid-winter counts of the species were received from only 16 sites. The status of the species in Iran is reviewed, and a map has been prepared showing the location of all the sites at which the species has been recorded. The highest number of birds recorded in Iran since the 1960s was a flock of 6,650 individuals in Miankaleh Protected Area in December 1972, while in 2007 and 2008, the total numbers recorded in Iran were only 264 and 26 individuals respectively.
