A mandarin duck unfolds its wings on the Solyonaya Protoka River in Vladivostok, Russia on April 14, 2020. The birds have flown in to nest in the Primorye Territory and are pairing up to hatch ducklings in July; they will migrate to Japan, Korea, and Southeast Asia after the first frosts hit in autumn. Russian laws ban hunting mandarin ducks, which are listed in the Red Book as an endangered species. (Photo by Yuri Smityuk/TASS)
