Russian scientists have completed an expedition in the Kara sea, which has estimated the number of gulls in the Arctic. This was reported TASS the head of the expedition, ornithologist Maria Gavrilo.
Gavrilo said that during the expedition the participants have studied the island of Haberga, red-Navy, stretch of coast of the Islands and the Bolshevik October Revolution and the island Home. They also visited the island of Solitude, Sergei Kirov, Visa, Schmidt and Komsomolets.
As it was established researchers, this year for the birds was unfavourable. “The number of the colonies was low and the breeding season late… In some colonies, such as key colony on the island Home, the birds began to nest, but then for some reason the nest emptied, we found an empty nest, devastated,” said the leader of the expedition.
According to her, probably this situation has arisen because of a long spring: this year winter in the area of the birds was very snowy, causing nesting sites free from snow later, and the birds not enough food. In addition, as emphasized by Gabriel, the white gulls are an indicator of the status of the Arctic ecosystem, so if the decline in their numbers across the region are confirmed, it would mean that the entire ecosystem is in a vulnerable state.
Russian specialists carried out a coordinated calculation of the birds at the same time with their foreign colleagues from Norway, Denmark and Canada. The results of the joint research across the Arctic will lead to the end of the year.
The expedition started in mid-July in the framework of the national project “Science”, which involves implies an increase in the number of marine expeditions to 250 by 2024. Only its implementation is planned to more than 625 billion rubles.
