Black guillemots thrive in and around Bangor harbour and have been nesting here since at least 1911. During the reconstruction of the harbour in the 1970s and 1980s local people campaigned to ensure that nesting holes were maintained in the new pier and marina and that no birds were harmed during the building work. They are usually seen from early March to mid summer, laying 1 or 2 eggs in mid May. The birds are very friendly and usually allow humans to get within a few feet of them on the pier wall.
