The common rosefinch (Carpodacus erythrinus) or scarlet rosefinch
A wonderful beautiful bird! I found them everywhere. And in mixed forests, and on the shore, and in the steppe zone. You are not confusing their charming whistling songs with anyone else. As I wrote earlier, their songs can be voiced as "nice to meet you!".
Bird cautious, but not particularly shy, you need to let it know that you are not dangerous, and not to make sudden movements. And these birds are easily lured via sounds.
