The Black Guillemot had a Radio Lancashire slot today and a visit to see if they had not promptly departed revealed one bird in the water below the jetty but bad light preventing seeing whether one was 'in the hole'. Communication with Alan Davies, the Conwy warden, suggests that the behaviour of these birds is very similar to the Fishguard harbour prospective colonists - plenty of display, mainly from the male but lukewarm female reaction. As Gavin Thomas pointed out, this might be because both the Heysham and Fishguard females are first summers.
