HORNED GREBE. 567 



innei qnills white ; lower parts pale silvery-ash, the sides watered or obscurely mottled, 

 sometimes obviously speckled with dusky ; bill black, more or less yellow at base. 

 The young will be recognized by these last characters, joined with the peculiar dimen- 

 sions and proportions. 



Habitat, the typical form, Europe. Var. hoUolU from Greenland and North America ; 

 with this Asiatic and Japanese specimens are said to agree. 



Rare spring and fall migrant, perhaps also winter resident. It has 

 been taken several times on the lake, at the St. Mary's and Licking 

 Reservoirs and on the Scioto River, at Circleville, by Dr. Howard E. 

 Jones.

Tarsus about equal to the middle toe without its claw ; bill much shorter than the 

 head, little more than half the tarsus, compressed, higher than wide at the nqstrils, 

 rather obtuse ; crests and ruffs highly developed. Small, length, about 14 ; extent, 24 ; 

 wing, 6 or less; bill, about f ; tarsus, IJ. Adult: — Above, dark-brown, the feathers 

 paler edged ; below, silvery-white, the sides mixed dusky and reddish ; most of the 

 secondaries white ; fore neck and upper breast brownish-red ; head glossy black, includ- 

 ing the ruff; a broad band over the eye, to and including the .occipital crests, brownish- 

 ish-yellow ; bill black, yellow-tipped. The young differ as in other species, but always 

 recognizable by the above measurements and proportions. 



Habitat, North America. Europe. Asia. 



Rather common spring and fall migrant and summer resident, most 

 frequently seen in the fall. Audubon states that it breeds in Northern 

 Ohio, and Mr. Langdon gives the following regarding their supposed nest- 

 ing in Ottawa county at the present time : 



" Two sets of eggs taken July 2d, I refer, with a query, to this species as the birds 

 were not seen in either instance. They present such differences, however, in shape, 

 coloration and complementary number, that they can hardly be credited to P. podiaepa, 

 and I therefore prefer to consider them under the head of P. oornmtus, for the present at 

 least. 



"These eggs are chalky- white, with a faint, though definite, tinge of pale bluish- 

 green, much like the tint of the Least Bittern's eggs, and very unlike the pale 

 whitey- brown of the eggs of P.podAceps observed by us ; they are also more elongated 

 in shape than the ordinary egg of P. podweps, and taper nearly equally toward both 

 ends, which are decidedly pointed, rather more so than the eggs of P. podiceps; another 

 important point of distinction is the number in a full set, whi«h is apparently but two.
