134 THE BIRDS OF BERKS AND BUCKS. 



On the Qth of December, 1867, a Grebe of this 

 species was killed upon the Thames at Datchet, and 

 passed into Mr. Ferryman's hands for preservation. 

 About the same time I heard of another specimen of 

 this bird which was shot on the Thames, close to 

 Eton. 



RED-THROATED DIVER (Colymbus septentrionalis). 

 Local name, Silver Grebe. This is the commonest of 

 the three species of Divers, and some are killed on 

 the river nearly every winter, especially if the weather 

 happens to be severe. A male bird of this species, 

 in good plumage, was killed by Mr. S. Hall, of 

 Windsor, on the water opposite Clewer Mill : this 

 was in the depth of a severe winter, about fifteen 

 years ago. A young one was shot on the Thames, 

 close to the village of Datchet, in the winter of 

 1863-64, and was stuffed by Mr. Ferryman. Several 

 examples have occurred near Maidenhead and Surley ; 

 others have been shot on the river at Windsor, 

 always in winter. Individuals have been taken at 

 Reading and Hungerford; and a single bird of this 

 species was procured near Burnham some years since. 



A Red-throated Diver is preserved in the fine col- 

 lection at Formosa, near Cookham, which was shot 

 in the immediate neighbourhood by Mr. Briggs, a 

 few winters ago. 



An immature bird was shot opposite Tull's Lock, 

 Windsor, by a man named Joel, in 1864; it was 

 described to me as a ' Silver Grebe,' but on inspection
