The stream is a down chorus walk in Parc del Guinardó in Barcelona, Sunday morning 6-7 AM CET.

Parc del Guinardó drapes over a hillside between El Carmel and Horta districts in Barcelona. Stone paths curve like they remember something. Up top, remnants of civil war defenses crumble into the view. We expect to hear the Serin, Blackbird, Sardinian Warbler, Monk Parakeet, among others.
