Porthcawl seawatch [1030 - 1400hrs]
1030hrs - 35/min
1100hrs - 42/min
1130hrs - 78/min
1200hrs - 83/min
1230hrs - 59/min
1300hrs - 46/min
1330hrs - 32/min
Although the total figure maybe regarded as a best guess estimate and not a completely accurate count. I used the1030hrs total for the next 30mins giving a total of 1050 (35*30) birds between 1030 - 1059. Then repeated this for the next 1/2 hr spell and so on. Working on this premise, the total for the 3 1/2 period would make a total of 11,250 birds. Next time I will try the same method at 15min intervals for even greater accuracy. The peak count coincides with the hour/hours after high tide when birds start to leave the upper channel as the tide drops.
Other birds seen :- 2 Storm Petrel [1 d/c @ 1042hrs, 1 u/c @ 1316hrs], 2 Common Tern [d/c @ 1220hrs], 26 Fulmar, 29 Gannet, 4 Guillemot.
Other observeres present - M. Meehan, G. Roblin
