PART II 
ANNOTATED LIST 
1. Colymbus holbelli Holbcell’s Grebe. Rare 
winter visitant, apparently included by Barnard and 
Pennock upon personal observation. I have record 
of a flock of six observed on Valley Forge dam, Feb. 
IO, 1903, and there are two recent records at Ken- 
nett Square, Feb. 9, 1904, and Feb. 15, 1912, the 
last a capture (Pennock, Cassinia, viii, 543; XVl, 44). 
2. Colymbus auritus Horned Grebe. Rather rare 
transient visitant, though listed by all but Mont- 
gomery. Mar. 29-Apr. zo. I have a female (No. 
580, coll. F. L. B.) found dead under the telegraph 
wires at Paoli, Apr. 20, 1896 (Wilson Bulletin, No. 
8,6). The additional records that have come to my 
notice are: Westtown, Mar. 29, 1911, by G. H. 
Haliett, and Apr. 5, 1913, by Emily M. Webster ; 
Kennett Square, Apr. 16, 1914, by C. A. Thomas 
(Cass., xv, 53; xvii, 40; xviii, 50). There are no 
spring dates. 
3. Podilymbus podiceps Pied-billed Grebe, ‘“dab- 
chick,” “dipper,” “hell diver,” “little diver.” Not 
very common transient, most frequent in spring. 
Apr. 7 (1911)-May 2 (1915); Ave. 4 years, Apr. 
12. ‘Two fall records are available both at Berwyn, 
Sept. 25, 1902, and Aug. 27, 1913. In Highland 
Twp. it is sometimes found in winter. A living 
specimen was taken from a flock of five or six on 
Buck run, in December, 1902 (Wilson MS.).
