The Black-throated Diver is a not unfrequent visitor 

 to our coasts in winter, but it breeds regularly in 

 several of the lochs of the northern counties of Scotland 

 and in many of the islands of the Outer Hebrides and in 

 the Orkneys. Lord Lilford includes it in his ' Birds of 

 Northamptonshire,' an immature bird having been killed 

 on Naseby Reservoir on 25th October, 1881. Two 

 others are mentioned as having been obtained near the 

 borders of the county. [0. S.]
