It's the culmination of an epic journey, from a group of islands in the Arctic Ocean to Dumfries and Galloway.
The entire barnacle geese population from Svalbard off the coast of Norway will winter on the Solway Firth.
After almost dying out in the 1940s, at its peak, more than 35,000 are set to arrive here this year.
Many have already made the journey.
Tens of thousands of barnacle geese are arriving in the region to winter on the Solway Firth.
The birds have travelled from a group of islands in the Arctic Ocean and have drawn in bird watchers from all over the UK

Tens of thousands of barnacle geese have begun arriving in the region for winter on the Solway Firth.
The birds have travelled from a group of islands in the Arctic Ocean. They draw in bird watchers from all over the UK.
In 2012 there was a row over proposals to cull 200 Canada Geese on Windermere.
It was postponed and now the two sides are working together on a plan to manage the problem.
The RSPCA, who were opposed to killing the birds, and rangers from the national park have joined forces.
Hundreds of the geese have now been ringed in an attempt to track their movements, as Samantha Parker reports:
A joint operation between the RSPCA and the Windermere Geese Management Group is being carried out to help understand and track geese in the area.
By ringing a number of birds, experts and wildlife officers are hoping to monitor where the geese come from and why.
