Amongst a recent batch of ringing recoveries received
from the BTO, via our partners at the Wildfowl and Wetlands Trust, came quite an
extraordinary movement of one of our Greylag Geese - relating to a gosling caught
with our team of volunteers in the annual round up on the 30th May
2017, pictured below. It was subsequently found on Sanday, on the Scottish Island
of Orkney – c604km to the north-east on 8th September 2018. This
is by far the furthest one of ‘our’ 1200 Greylags has been
reported – most seem to head south towards the Humber estuary and
down into Lincolnshire, whilst some move north-west towards the Harrogate and
Ripon area. We’ve had two more into Scotland before, to Dumfries and
Galloway and to Loch Eye in the Highlands, but not as far as this individual
which also made a significant flight across the North Sea.
From Greylag Geese ringed elsewhere there is also growing
evidence that birds from the valley take part in the developing moult migration
to Cumbria and the Lake District by Yorkshire birds, whilst we’ve also had several
Icelandic birds and three from Sweden seen in the valley – so whilst they may just
appear to be a local Greylag Goose, who knows
where they may have come from. We still have so much to find about these
birds – please let us know if you come across any of the birds wearing colour-rings in
and around the area.
