- Аннотация: As in 2020, due to the high level of water in the wetlands and the COVID-19 pandemic travel restrictions inside China, waterbirds flourished in 2021. Collectors of crane eggs and chicks in in China had to stop their activities and the long-awaited pressure from the Chinese government on National Nature Reserves, which hold hundreds of captive cranes for commercial use, took away poachers’ profit. Estimated number of Hooded Cranes staging at Muraviovoka Park for about 4 weeks in the fall was at least a thousand in 2020 (there was no comprehensive survey in 2020). In 2021, we also could not conduct a proper survey, but there were fewer (~400) Hooded Cranes roosting in the Park wetlands, since the birds could safely stay every night in their feeding areas – crop fields covered with water. For example, in such fields at Razdol’noye village, Hooded Cranes fed and roosted together with White-naped, Eurasian, and Siberian Cranes. In mid-May 2021, six Siberian Cranes stayed for three days in the Park with four Red-crowned Cranes. In the fall, we counted 15 Eurasian Cranes in the Park. Frequent pouring rains in the second half of June led to further flooding of the southern and southwestern parts of the Park. A few our lakes, including Kapustikha Lake, were connected by streams with Giltchin River even before this flooding, resulting in fish from the Amur River coming into the Park’s lakes and in abundance of amphibians and fish in the lakes and flooded wet meadows. So, it was not surprising that throughout the summer of 2021 we could watch Oriental Storks feeding near their nests in different parts of the Park. 30 pairs raised chicks in the Park – twice as many as in 2020. Nesting success of this species, which may raise up to six chicks per pair, mainly depends on availability of nesting trees and food (fewer chicks are raised in dry years). Good water conditions resulted in significantly higher numbers of ducks, such as Falcated Duck, Spotted Bill Duck, Little Grebe, and White-winged Black Tern, which nested even in flooded parts of crop fields on the Amur River terrace. At the same time, nests built in early April were flooded and abandoned in late April – May. In late June, the Amur River flood waters drowned rodents and chicks of pheasants, who could not yet fly well.
