24 BIRDS OF OHIO. 
2. (3.) CotymsBus auritus Linn. 288. 
Horned Grebe. 
Synonyms: Dytes auritus, Podiceps cornutus. 
Audubon, Orn. Biog., III, 1835, 429. 
While this grebe is not common during the migrations 
it can hardly be called rare in most parts of the state. It 
is somewhat regular as a migrant, but may be fosnd during 
the winter. Companies of a dozen or more individuals in 
full spring dress are not infrequent on Lake Erie. During 
the southward migration there is a strong tendency for the 
birds to occur two at a time on the smaller waters. The 
report of the breeding of this species in Ottawa covnty has 
not been confirmed. 
This grebe is as good a diver as the more familiar Pied- 
billed, for which it is often mistaken. The slenderness of 
the bill should always easily distinguish it from that species. 
In the migrations the Horned Grebe reaches Oberlin 
about the middle of April and remains until about the first 
of May. It returns easly in October and tarries until ice 
forms on the ponds, and may be found at any time during 
the winter about open water. 
38. (6.) PopiLymMBuUs PODICEPS (Linn.). 289. 
Pied-billed Grebe. 
Synonyms: Podiceps carolinensis, Colymbus podiceps. 
Pied-billed Dabchick, Thick-billed Grebe, Dabchick, Dipper, 
Didipper, Diedapper, Water-witch, Hell-diver, Devil-diver. 
Kirtland, Ohio Geol. Surv., 1838, 166, 187. 
This is the most familiar grebe in Ohio, known by a di- 
versity of names to suit the experiences of each individual 
hunter. However, the modern shot-gun or rifle is too quick 
for him. To be sure he sometimes succeeds in dodging the 
lead thrown at him, but far oftener he falls a victim to it, 
as the breasts which may be seen on hats and in boas too 
well show. 
This grebe nests sparingly all over the state where con- 
ditions may be favorable. One could hardly call the species
