AFTER successfully connecting
with the Amur Falcon in Cornwall
in July 2017, Ernie Davis has
become the  rst person to see

850 bird species in the Western
Palearctic (WP).
Having spent years searching
for hard-to- nd birds in some of

the region’s most remote areas,
including the Cape Verde Islands,
Western Sahara, the Upper Nile
Valley in Egypt and Russia’s Ural
Mountains and
south-eastern
steppe, Ernie
just had to
cross the county
border from his
home in south
Devon to get his
landmark 850th
tick.
Amur Falcon
would have
been high on
the wants lists
of many of
the region’s
biggest listers,
particularly those
in Britain. The

one previous British Amur spent
a month in residence at Tophill
Low, East Yorkshire, from 14
September-15 October 2008, but
was believed to be a Red-footed
Falcon – until it was reidenti ed
from photos, by which time the
bird had moved on.
In an increasingly competitive
WP listing  eld, Ernie Davis is
three species clear of Pierre-André
Crochet of France, and six ahead
of Chris Bell from Co Durham.
Based on BWP boundaries, just
18 birders have so far passed
the 800-species mark, with 71 on
700 species or more.

■ International protection for UK’s
second-largest seabird colony
A huge new Special Protection Area (SPA)
has been designated off the Northumberland
coast, giving 200,000 seabirds greater
security. The Northumberland Marine SPA
stretches 12 miles from the coast into the
North Sea.

 News round-up


NORTHERN SHRIKE SPLIT
THE recent update of the International Ornithological
Congress’s world list, as used by Birdwatch and from
next year the British Ornithologists’ Union, included
several splits relevant to the Western Palearctic, some
of which were covered in last month’s Listcheck.
However, also of note is the separation of
Northern Shrike Lanius borealis, the mainly North
American counterpart of Great Grey Shrike L
excubitor, of which Northern until now was usually

considered a subspecies.
DNA analysis has shown Northern to be more
closely related to Loggerhead Shrike L ludovicianus,
another widespread Nearctic species.
However, the new species is not just con ned to
North America. Morphological similarities between
Northern and Siberian forms of Great Grey Shrike
have long been noted, and the following four Siberian
subspecies are now subsumed into the former:
sibiricus, bianchii, mollis and funereus.
The taxonomy of the grey shrikes
is still not yet fully resolved, as the
position of the nominate Iberian
subspecies of Southern Grey Shrike
L meridionalis meridionalis remains
uncertain; it currently appears to
form a clade with L borealis to judge
by analysis of its mitochondrial
DNA, but is closer to L excubitor in
plumage and range.
Northern Shrike has occurred as
a vagrant to Finland (one record),
Norway (one
record) and
Ukraine (seven).
There is a
pending record
for the Azores. ■

will be the fi rst for the islands.
