Here's another 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.

Yellowhammer
This little sparrow-sized yellow-brown bird can be found here all year round. Interestingly, each male bird sings only one particular 'dialect song', and any area is usually inhabited by Yelowhammers singing in a single dialect.
Blackbird
The powerhouse of the dawn and evening chorus, Blackbirds can be heard already in the second half of March. Indefatigable and beautiful singers, as noted by The Beatles, among others.
White Wagtail
A nimble and attractive bird that loves to live close to humans, some people consider the White Wagtail as the true national bird of Latvia despite the better-known claim of the White Stork.
