As predicted, the north and north westerly airflow of the
last week produced an arrival of Pink-footed
Geese and Whooper Swans to the
UK, along with a few Grey Phalaropes
and a distinct movement/arrival of Wigeon.
The same winds that brought the geese and swans here were probably also
responsible for the arrival of Lapland
Buntings, with birds being seen from the northern isles to Scilly. Perhaps
indicating a late breeding season, Swifts
continued to trickle out of the UK while Swallows
and martins are beginning to move in force. With winds becoming lighter towards
the end of the week Meadow Pipit
migration began to ramp up too.

Whilst the influence of hurricane Dorian wasn’t felt
immediately last week the arrival of several North American waders this week
showed it did have an effect, several Semi-palmated,
White-rumped and Buff-breasted
Sandpipers were found but it was the double figures of American Golden Plover that stole the show, at least fifteen were
found. There was also a small arrival of
Long-billed Dowitchers, but the star billing of the Dorian effect has to go
to the Common Nighthawk that was
found in Argyll.
Species Focus
Lapland Bunting
is a scarce passage and winter migrant to the UK, typically arriving here
towards the end of September. It is one of the most abundant and widespread
arctic passerines, breeding from southern Norway across Siberia to the Bering
Sea and from Alaska east across Canada to west and southeast Greenland. Most
winters between 200 and 500 are typical in the UK but in some winters many more
are found, mostly in saltmarsh or coastal fields but not exclusively, with
birds often found far inland in similar habitat.
The dry, rolling ‘tiddlip-tew’ flight call, uttered on
take-off or whilst flying over, is often the first sign of a Lapland Bunting but when located on the
ground it is a very distinctive bird, showing an obvious chestnut nape, dark,
spotted upper breast on clean white underparts, and a black-framed pale cheek
below a broad supercilium flaring behind the eye. With a good showing already this autumn, it might be one to
look out for this winter.
During the weekend the country will mostly be sat in a
southeast and southerly airflow, but as the week progress the winds in the
south are going to swing to the southwest and in the north remain in the east,
at times coming straight out of Scandinavia.

Over the next couple of days there ought to be a mass exodus
of Swallows and House Martins, taking advantage of the relatively light winds and
warm temperatures as a result of a high-pressure system centred to the south
and east of us. There is a low pressure system centred in the Atlantic to the
south of Greenland and Iceland that may well bring a few more North American
waders to Ireland’s shores, and who knows? Maybe the first Red-eyed Vireo of the autumn.
Enjoying a week of easterly airflow the northern isles ought to shine,
with the first push of Yellow-browed
Warblers, along with a few Common
Rosefinches and maybe something much rarer like a Collared Flycatcher in the offing. With Pallid Harrier being a scarce migrant these days we could expect a
few of these to be found during the next week. The warm southerly winds might
also bring the odd Hoopoe, Alpine Swift,
Red-rumped Swallow and Red-backed
and Woodchat Shrike to southern
Britain.
Mid to late September is a time for finches to start moving
with Linnet being the herald of this,
and we should also see a distinct increase in the numbers of Wigeon, Teal and Red-throated Divers on the move. The easterly airflow should bring
the first Dark-bellied Brent Geese
to many sites along the east and south coast. Mid-September to mid-October is
when migration peaks and we will be keeping a very close eye on the weather
forecast during the next few weeks to help us keep ahead of the game.
