A dull drizzly day of strong south easterly wind so we headed again for Brevig
and another look at the sooty shearwater passage down the east of the island.
It wasn't as easy today, with distant mist making viewing difficult or
impossible. However occasionally the shearwaters came a little closer or the
mist cleared for a while and we did manage to see at least 15 birds.
A useful characteristic of sooty shearwater is that in strong winds they tend
to glide in long graceful arcs, shearing low over the water and then rising high into
the air before dropping again. This distinguishes them from Manx shearwater even at long distances.
I've seen quite a few sooties in the past but never knowingly seen this flight
action before so the past couple of days have been very educational.
They also have a different wing shape to Manx, having longer and narrower
wings. Of course they also have dark bellies and silvery underwings but seeing
that on a dull day in strong winds at a range of two miles is quite a challenge!
Still, I'm pretty sure that all of the birds we have seen did have dark
bellies.
This afternoon we headed for Eoligarry where despite the drizzle and wind we managed four species of raptor, white-tailed eagle, ringtail hen harrier,
buzzard and merlin, plus juvenile wheatear at the jetty, 80 golden plover and
red-throated diver. So not a bad day!
