When were they released ?  Hunters have been known to take cages full of  birds up the Barranc de  Caramella. leave them overnight and then release at dawn.  The birds are so keen to escape that they make easy targets for the gun happy hunters (?).

They were released day before yesterday. about 5 in the evening, to multiply ready for the hunting season.
