Tweet of the Day is the voice of birds and our relationship with them, from around the world.

Miranda Krestovnikoff presents the long distant migrant Arctic warbler. These classic olive-grey warblers, slightly smaller than the European robin, with a pale eye-stripe, winter in south-east Asia, but each spring fly to northern forests to breed. This can be as far as Finland, up to 13,000 kilometres away as well as Arctic and sub-Arctic Russia, Japan and even Alaska. They do this to feed on the bountiful supply of insects which proliferate during the 24-hour daylight of an Arctic summer. A few make it to Britain, the Northern Isles, but whether they finally return to Asia is not known. Show less
