First sighting of cormorant in area?

Is this the first sighting of a cormorant in our area?

These are coastal birds and we are at least thirty miles from the sea

Some though are known to winter inland.
But 30 miles?....

In China and Japan cormorants are trained to fish so it is somewhat ironic to see this cormorant perched on an old beer barrel, used as a buoy, on the former reservoir, above Bridge of Allan, which is now used by the local fishing club.


I wonder if any local ornithologists can throw light on this subject.
