Notes on the Birds. 319 
1. COLYMBUS AURITUS (Linnieus). HORNED GREBE. (3) 
' A rare spring and fall migrant, probably in all the counties, though I 
liave no definite record for Carroll or Monroe. The only record for Vigo 
is of one brought to Professor Blatchley in the fall of 1890 by a boy who 
found it tied as a decoy in the Wabash River near Terre Haute. 
2. PODILYMBUS PODICEPS (Linnzeus). PIED-BILLED GREBE. (6) 
Any one who has spent much time in the spring or fall about any of the 
small lakes with which northern Indiana is so abundantly supplied, or along 
the larger streams of the state, has doubtless become familiar with the queer 
little duck-like birds which he probably called “helldivers”’. 
The most common and best known species is the Pied-billed Grebe, other- 
wise known as helldiver, dabchick, or waterwitch. It is a summer resident 
in the ponds about Terre Haute and elsewhere along the Wabash River. 
Vigo County: Usually a few were seen every time a visit was made to 
the Five-mile Pond or the Goose Pond; occasionally seen along the old 
canal. When at the Goose Pond, nine miles south of Terre Haute, May 3, 
1890, Mr. U. O. Cox and I found a nest of this curious, witch-like little diver. 
It was a floating mass of dead flags and Scirpus stems, more or less matted 
together with mud. The eggs, of which there were seven, were covered up 
with nest material when found, and were very dirty. Incubation had slight- 
ly advanced. Four of the eggs measured, in inches, 1.66x 1.12, two 1.70 x 
1.12, and one 1.66 x 1.09. 
Doubtless other nests could have been found in this pond had we searched 
thoroughly. It no doubt nests in the Five-mile Pond, in Greenfield Bayou, 
and in other similar places in the county. 
Carroll County: A few said to remain through the winter in open places 
in the Wabash near the Georgetown mill. I do not remember ever to have 
seen it on Deer Creek or Wild Cat, but it was seen on the Wabash occasion- 
ally. -On February 21, 1885, my friend. Charles Metsker, saw one in the 
Wabash near the Pittsburg dam, and Wm. Coble told me that a few usually 
remain all. winter in air-holes in the Wabash near the Georgetown mill. 
I never saw this species in Monroe County. 
3. GAVIA IMMER (Briinnich). Loon. (7) 
A rare spring and fall migrant. 
Carroll County: Seen once on Wild Cat Creek many years ago. 
Vigo County: One seen on the Wabash November 6, 1886, and another 
a short distance below Durkee’s Ferry, in April, 1889. No record for Mon- 
roe County. 
4. TLARUS ARGENTATUS (Pontoppidan). TWERRING GULL. (5) 
Rare spring and fall migrant. 
Carroll County: Occasionally seen on the Wabash about Pittsburg and 
above. 
Vigo County: There was a specimen in Dr. Scovell’s collection obtained 
on the Wabash near Terre Haute many years ago. No Monroe County rec- 
ord.
