Boiler Bay Seawatch

29 April


After yesterday’s great movement we were back to the slow migration seen last week. Not much can be said about the seawatch today. Small flocks of Western/Least Sandpiper along with Pacific Loon were heading north and some movement of Sooty Shearwater moving south very far in the horizon. Counting time: 05:50-10:50. 4849 seabirds of 29 species counted. Weather was mostly nice even though some areas of rain passed just north and south of Boiler Bay. Wind was slow from southwest < 3 m/s (< 7mph).
