    After being absent from Cornwall for 54 years, the Cornish choughs returned 11 years ago

    Researchers from Aberdeen University took DNA samples to get a genetic fingerprint of the birds and their results suggest that the Cornish chough population, came from the Republic of Ireland.

    For Dr Jane Reid this is a surprising finding because usually the chough was a "very, very sedentary" bird. Quoted by BBC, Dr Reid said that "genetic evidence now suggests the new Cornish ones came from some point along the coast of southern Ireland."
    "Our study also showed that all the populations we sampled right though from Scotland, Wales, Brittany, Ireland, are really quite genetically distinct from each other, which suggests that typically there is very little movement between them."

    Choughs belong to the crow family and they have a red beak and legs and an excitable high-pitched 'chi-ow' call from which it gets its name.
