If you're interested in this, you should definitely check out the documentary Birdmen of Istanbul[1]. Turn on captions for English subtitles. It tells the story of the residents of bird cafes in Istanbul and the very old tradition of goldfinch, greenfinch and siskin training for singing.

They're completely obsessed with birds, dedicating their whole lives to finding and training them. They have special vocabulary for classifying different bird songs. It's known to be a dying tradition as well but this documentary might have rekindled the interest.

Volume 2 ("The Desolate One") of the 2015 Portuguese film trilogy "Arabian Nights" has a 40-min story about bird trainers, as well. They love their birds, they love their songs, and they love to compete.
