Conservationists in Northumberland have called for pet owners to get their dogs under control after footage was shared of a dog chasing nesting shorebirds at the Aln Estuary.
The winter months see rare species of wading birds of 'international importance' feeding and roosting on the Northumberland coast, such as ring plovers, purple sand pipers and sanderlings.
However, being disturbed can harm their chances of survival.
