This video from the USA is called Wood Thrush singing song close-up. The wood thrush is one of the over 9,000 animal species with sound recordings at the Macaulay Library of Natural Sounds from the USA, which is on the Internet.

Nature Zen: Audio Library of Nature
By Gwen Pearson
Stuck at your desk? Need a soundtrack to mellow out on a Monday? I have just what you need! This hour-long recording of a dawn chorus in the mountains of Costa Rica is lovely to listen to, especially as winter edges closer here in the Northern Hemisphere. You might also like an interlude in a very different sounding forest in Queensland, Australia.
The Cornell Lab of Ornithology is a massive digital repository of cool stuff, and a big piece of it is the Macaulay Library of Natural Sounds‘s audio and video recordings of wildlife all over the world. Since 1920 scientists at Cornell have been recording wildlife, at first mostly birds, and then branching out to other animals.
In early 2013, they migrated over 150,000 digital recordings online, dating from 1929 to the present. It’s over 10 terabytes of data, representing more than 9,000 species. This museum has thrown open the doors and invites you into rummage around their collection. Beware, though–this library of natural recordings is huge and addictive.
