The social structure of a communal roost of Choughs Pyrrhocorax pyrrhocorax was studied between July and September 1985. Different age classes within the roost were spatially segregated. Third‐year birds were significantly more likely to attack another Chough and roosted in the densest part of the roosting flock. First‐year birds roosted significantly lower down the roost cliff and on the periphery of the flock.
