THE BLACK-NECKED OR EARED GREBE. 
PODICIPES NIGRICGLLIs, C. L. Brehm. 
This Grebe is rather smaller than the preceding species ; and is 
chiefly a southern bird which at intervals pushes its migrations in 
spring and summer as far to the north-west as the British Islands ; 
it also visits us—though more rarely—in autumn and winter, to 
escape the severe cold of the Continent. Individuals in complete 
breeding-dress have been obtained occasionally in most of our 
southern and eastern counties ; and there is even strong presumptive 
evidence that the bird has bred in Norfolk, for Booth had “a full- 
plumaged adult and a couple of downy mites” brought to him by a 
marshman (cf Tr. Norfolk & N. Nat. Soc. vol. iv. p. 416, footnote). 
Northward, this Grebe is fairly common on the coast of Northum- 
berland; beyond the Tweed, however, it becomes scarcer, though 
it can be traced to the Orkneys, but not to the Shetlands. On the 
west of Scotland the only authenticated occurrences appear to be 
those of an adult on Loch Sunart in the spring of 1866, one in Skye 
in January 1895, and a pair shot on the Nith. A few instances are 
on record from Cumberland, Lancashire, and tke Isle of Man; while 
the bird is a regular visitor in February and March to the coast of 
Merionethshire, and has been obtained in Pembrokeshire. In
