English: :This is something amazing and unusual for me, also a very lucky catch: a flock of 15-20 individuals playing, singing and chasing each others in my garden, very close to the window from which I've recorded them. Here's what happened: one of the birds picked up a dry leaf from the ground and the others chased him walking, then they rose in flight together noisily (as evidenced from the recording) and chased each others around the garden until one of them grabbed the leaf and the game started again, over and over for about 15 minutes.

Note: this is an agonistic behavior typical of Baywings, known as "Leaf Gathering" (Fraga 1991).
