Millions of this large, leisurely shearing shearwater
breed on the tussocky islands within the Tristan da Cunha group and
also on other southern Atlantic islands. Its long
post-breeding transequatorial migration leads northwest to rich
feeding grounds off the coast of Greenland, where it overwinters
(effectively during our ‘boreal’ summer). It then migrates
clockwise around the NE Atlantic during our autumn, returning then
back to the Southern Hemisphere. Spring records in the NE
Atlantic are rare†.
Great Britain
Rare in spring, small numbers appear annually mid-summer
to autumn off west Cornwall, but stormy conditions with strong winds
from the southwest quarter can exceptionally result daily counts of
thousands†. It is rarely reported from
headlands away from the far SW and E of Devon along the S coast it
is a vagrant, with only four 20th century records for Dorset†.
Devon
Recorded in only 22 of a 41-year period (1969 - 2010) on
51 dates (excluding the long-staying flock off north Devon coast in
autumn 2002)†. However, even under optimal
conditions, only three dates exist with three-figure counts†, and in only six of the
41-year period (1969 - 2010) have more than five individuals been
recorded in Devon†.
