RED-NECKED GREBE. 413 



cept at the base, where it is yellow ; the irides red ; top of 

 the head, and back of the neck, rich dark brown, almost 

 black ; cheeks, chin, and throat fine bluish-grey, margined 

 with white ; back, wing-coverts, tertials, and rump dark 

 brown ; wing-primaries nearly black ; the secondaries white ; 

 neck in front rich chestnut red ; breast and belly silky 

 white ; sides under the wing, the flanks, and under tail- 

 coverts greyish-brown ; legs and toes dark greenish-brown 

 on the outer surface, the inner surface greenish-yellow. 



The whole length is sixteen inches and a half. From 

 the carpal joint to the end of the primaries seven inches. 



Young birds have the head and neck behind dusky 

 brown ; the back and wings neither so dark in the brown 

 colour, nor so uniform in the tint, as in the adult birds, 

 the margins of the feathers being ash brown ; chin, throat, 

 and neck in front greyish-white ; other parts as in the 

 more adult birds. I have seen young birds more than half 

 grown which exhibited longitudinal dark stripes on a light 

 ground colour down the neck. 



The figure below represents the form of the foot in the 

 Grebes.
