Dialect clue to decline in Western Isles corn buntings
Variations in the songs of different groups of corn buntings in the Western Isles have helped scientists to chart the decline in numbers of the birds. By studying the pattern of male birds' songs, researchers can identify different groups of buntings. In the past males could find enough mates within their own groups. But Aberystwyth University scientists have found the dialect groups are beginning to mix together suggesting males are flying further to find mates.
