Sound recorded by Paco and Fernando for the workshop at Ramon d'Alòs-Moner public library and IES Barri Besòs school. Birds. Seagulls crawing at Diagonal Mar park, Barcelona. This is a characteristic sound of that park. Recorded with a Zoom H2 handy recorder. What we can hear at the beginning is the place where the sound was recorded, "el parque de los patos". This sound has not been edited.
