The ornithologists in the Caspian Sea carry out surveys at the beginning of each year of wintering waterfowl, most of which have the status of self-replicating biological resources of international importance. The 50th anniversary status report was held in the Turkmen sector of the Caspian Sea According to the already established tradition.
Wintering conditions turned out to be quite favorable for our feathered guests and their numerous flocks filled the rich in forages and coves protected from strong storms and bays near the coasts of our country. The migratory path of birds flying from nesting places in Western Europe and the northern half of the Asian continent at wintering grounds in the Caspian basin, the Red Sea, on water bodies and off the coast of Africa, the southern half of Asia, Indonesia, Australia, New Zealand and Polynesia.
The scientists not only conduct a census of the feathered population studying the flights of birds, but also catching chicks or adult birds with special traps, they wear metal rings that are original "bird passports", and in recent years also special electronic sensors that allow track their movement using satellite navigation in real time.
Over 13 thousand different bird species have been ringed in different years in the water areas of the Turkmenbashi Branch of the Hazar Nature Reserve of the State Committee for the Protection of the Environment and Land Resources. Through the International Ring Center in the Swedish capital of Stockholm have been received returns from 18 border and remote countries.
In the early 70's in Daradan - a vertically installed fine-meshed network on the protected islands of the Osushnye, a small red-bellied curlew sandpiper came into its nest in the subzone of the Arctic tundra of Siberia, and on wintering, it was ringed on the coast of South Africa, to the south of the Sahara. Thus, feathered migrants, due to the specificity of their way of life, freely cross borders and huge distances through the territory of many states. International Conventions and a number of environmental acts, many of which have been ratified by Turkmenistan, regulate their study, protection, reproduction and rational use by hunting communities in our time.
Thirty-two species with different statuses were caught in the register of wintering birds of the current year. Pleased especially protected red book flamingo, whose number was 1416 individuals. In 17 surveyed areas (47.2%), the category of waterfowl, which are the objects of amateur hunting, amounted to a group of one and a half dozen species with a total number of about 178 thousand individuals at the average multi-year level. Extrapolating the obtained data to other parts of the Caspian Sea is to mention, that the total stocks of game amounted to at least 300 thousand, a third of which fell to the share of coots.
The obtained data will be statistically processed and used to compile a survey of wintering grounds over a half-century period and will make it possible to make a scientific analysis of the state of hunting game reserves and provide valid recommendations for hunting management by the Turkmen-Fishery Union, the 80th anniversary of which will be celebrated this year. In general, the data obtained correspond to the worldwide trend of decreasing the reserves of the planet's biological resources, which is associated with global changes in bird habitats within their ranges. They show special sensitivity in places of nesting and mass wintering, the state of which maximally affects their numbers.
