Podilymbus podiceps (6). Pied-billed Grebe. 
Common from September 1 (’93) to March 31 (88, Res- 
ler), a few stay with us to breed, but, as far as I know, the 
nest has not been found in Maryland. Specimens have been 
taken on April 28 (93) and July 31 (’75, Resler), at Back 
River. At Hagerstown, in June (’80, Small), and near 
Westminster, early in September (’80, Fisher) nine, possibly a 
family, were taken in one day from a mill pond. At Wash- 
ington, common from August 25 to May (Richmond). 
Family Urinatorip=—Loons. 
Urinator imber (7). Loon. 
Fairly common during winter on ocean front, Chesapeake 
Bay, and larger waters of Maryland. In New Jersey it is 
given as arriving October 3 (Birds E. Pa. and N. J., 39), but 
I have only spring dates ranging from March 9 (’91, Fisher), at 
Legoe’s Point, to June 17 (’93, J. F. Hargreaves), when a very 
noisy pair were on the Gunpowder River, near the Pennsylvania 
Railroad bridge. Mr. W.S. Walker, of Chestertown, writes 
me that it is “one of the last birds to leave Chester River.” 
At Washington, from September to April 25 (Richmond). 
Audubon says (vii, 284): “the Loon breeds in various parts of 
the United States from Maryland to Maine. I have ascertained 
that it nestles in the former of these states on the Susquehanna 
River.” Not known to nest here now. 
Urinator lumme (11). Red-throated Loon. 
Occasionally taken on our waters during winter. On February 
16, 1878, the late A. Wolle presented the Maryland Academy 
of Sciences with shells taken from the stomach of one of these 
birds, presumably captured near Baltimore. 
“Not uncommon on the (Potomac) River during the winter 
months” (A.C.,110). “In the spring of 1882 one was caught in 
a gill net in the Potomac River, a few miles below Washington, 
and is now in the possession of Mr. O. N. Bryan, of Marshall
