I notice on The Gurn that some are suggesting that the Caper might be a Black Grouse. It is quite easy to mix the two, but I can confirm that this is definitely a Caper. Size and colour of wings - and particularly the large bill are the main give away.
As for it's well-being: it is lost and vulnerable in a town centre and people are right to be concerned. There are precious few of these iconic birds surviving in The Highlands and we need to treat this situation very sensitively to prevent a premature demise.
A number of expert authorities in the conservation field are aware of this ongoing situation and I will keep you updated. Please let me know of any more sightings.
