✔️The Siberian rubythroat (Calliope calliope)
This thin nightingale appears in the forests of Siberia with the appearance of the first foliage. They arrive in the territories they occupied last year, might say "welcome back home." They begin to actively sing songs informing others that the territory is occupied, as well as attract females, invite them to inspect the surroundings for nesting suitability.
By the way, this nightingale is not particularly shy, so you can sit next to him, naturally carefully keeping your distance, and enjoy his wonderful songs. His songs can tell where he was and what he saw.
The fact is that in his songs he uses previously heard sounds from nature or the voices of other birds.
For 3 years of observation, these nightingales often pronounce the voices of Great Tits and Pied Flycatchers. And once, in the forest, which is located near a residential area, a village, I heard the sounds of a car alarm in song of this nightingale.
