Interested in urban wildlife, birds in particular. Following the arrival of new species to consolidated urban areas (and not all are invaders !).
But my first request for help hasn't to do with urban species. 2 weeks ago I saw this duck in Fão (north Portugal) in the middle of mallards. Any idea of what it is?
Thanks
