Podilymbus podiceps (6). Pied-billed Grebe. 



Common from September 1 ('93) to March 31 ('88, Ees- 

 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 Ueinatoeid^ — 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
