17/05/18. Skokholm. Manx Shearwaters coming and going.

Tiny Skokholm has the densest Manx Shearwater colony on earth.

When it becomes dark, and the moon is either absent or obscured, the Manx Shearwaters make their move to leave their burrows, or to return to their burrows from the sea.   The photo above was of shearwaters in rafts at sea in St Brides Bay off Skomer  prior to sunset.

They all have quite different voices; some of this variation is down to gender, and some to individual differences.    The air is full of their movement.

This recording was made at 11:30pm on the track just before “the gap” as you head northeast from the lighthouse.  The photo below is of the same spot in sunlight:
