Barnacle geese have been tagged with satellite trackers amid concern planned offshore wind farms could affect their migration to the Arctic.

The Wildfowl and Wetlands Trust (WWT) said it had tagged five male Svalbard barnacle geese, which overwinter in the Solway Firth, with GPS trackers.

It is concerned offshore wind farms in the Firth of Forth and off the UK coast could be an obstacle for the birds.

The tracking will gather information on migration routes and altitudes.

The geese - which have been tagged at Caerlaverock Wetland Centre on the Solway Firth - are due to migrate to the High Arctic Norwegian archipelago of Svalbard later this month.
