Large gulls have been increasing at most sites around Northern Ireland, with particularly good annual data collected by the National Trust for Strangford Lough. In 2021, the numbers of Great Black-backed Gulls in the lough were at their highest since 1972, with 143 nests recorded.
Black Guillemots are a favourite of seabird monitoring volunteers in Northern Ireland, and we closed the census period with an incredible 80% of sites in NI covered for this species, with those sites left un-surveyed very unlikely to contain Black Guillemots. In 2021, a total of 718 Black Guillemots were counted around the coasts, with concentrations particularly high at The Maidens (60 individuals), Bangor (75 individuals), Lighthouse Island (60 individuals) and at Annalong Harbour (58 individuals). A volunteer-led productivity study found that their breeding success at Annalong was 0.5 chicks fledged per nest.
