The common rosefinch (Carpodacus erythrinus) or scarlet rosefinch
Judging by the redness of the plumage, this male is more than a year old, maybe even 2 or 3. The older the male, the brighter and more red in his head and abdomen. It’s like a tree cut ring :)
So this beautiful bird jumped off a tree and fumbled in the grass. But he was not looking for food, he was just wandering around and looking for something or someone.
