If you have any questions on the above, try to post them on http://www.rbcu.ru/forum/. It's the most popular forum on birding in Russia.
Although it's in Russian you can post your question in English and most probably someone will get back to you
Russian birders rarely visit this section of Birdforum as you can see...
