In coming days we'll bring you a selection of the original twittersphere's greatest hits so that by the time you're swinging lazily in a sun-drenched hammock you won't even need to open your eyes to know what's up in the branches above.
The recordings are courtesy of ornithologist Edmunds Račinsks, with photographs from Jānis Jansons.
Marsh Warbler
The song of the Marsh Warbler is amazingly diverse and complex. This species is also a talented impressionist, able to accurately reproduce the calls of other birds into its own.
Corncrake
Like other smaller birds of the fields, corncrakes are rarely seen as they like to hide among the vegetation whenever possible. Their call however is anything but shy and is the definitive sound of Midsummer celebrations.
Nightingale
Famously the inspiration of the poet John Keats (currently having the 200th anniversary of his death marked), the Nightingale is the possessor of one of the most beautiful voices of the natural world. You can expect to hear them in Latvia from the end of April when they "Singest of summer in full-throated ease".
