MANX SHEARWATER First Manx Shearwater was on land in North Haven on 12 March with the first fresh carcass found 14 March (maybe an inexperienced bird). 17 on surface between farm and north haven by 22 March. Flock 100 offshore 29 March. One adult with puffinosis was seen on Green Pond 26 May sometimes Manxies do survive the disease. Chicks began to be observed from 18 June (two in response rate burrows). Large rafts observed in August and fledglings on surface. Only young observed on surface by 12 September with few young observed from 15 September onwards. Single observations in October including 2 between farm and north haven on7 October. Last observed bird 17 October with a possible fresh carcass 21 October. Whole Island Manx Shearwater census Full report available on request: Perrins, C.M., Wood, M.J., Garroway, C.J., Boyle, D., Oakes, N., Revera, R., Collins, P., & Taylor, C. (2012) Skomer Island Manx Shearwater Census 2011. Wildlife Trust of South and West Wales. Executive Summary In 1998 a census was made of the whole island, and the adjacent islands of Skokholm and Middleholm, in order to try to establish the size of the breeding population; the Skomer population was estimated to be just over 101,000 breeding pairs. A second census was carried out in 2011. First, a set of study burrows was opened and a tape of the male call (normally only males respond to these) was played down each burrow several times during the course of incubation in order to establish the male response rate. Then the same tape was played down all the burrows in each of 288 randomly selected plots across the island and the number of responses recorded. Extrapolating responses from census plots to the whole island yielded an estimate of 125,112 ± 16,445 responses. Adjusting this figure to take account of the response rate yielded an estimate of 316,070 (SE ±14,688) breeding pairs. SOOTY SHEARWATER One 17 July. Two in St Brides Bay 5 September, One flew north 19 September. BALEARIC SHEARWATER One in St Brides Bay 5 September.
