the young. The birds were last seen on Aug. 3. 
No search was made on the following year, but an 
adult was seen July 3, and it doubtless was breed- 
ing. 
37. Ardea herodias herodias Great Blue Heron, 
“big kingfisher,” “big blue crane,” “big crane,” “big 
blue shitepoke,” ‘“‘blue crane,” “brother Jonathan,” 
“crane,” “fish crane,” ‘frog eater,” “giant heron,’ 
“sreat big fly-up-the-creek.” An irregularly com- 
mon transient and an occasional, solitary, non-breed- 
ing summer resident. Earliest date of arrival, Mar. 
31 (1900), and latest date of departure, Nov. 18 
(1912), in the vicinity of Berwyn. Montgomery 
noticed a pair during two summers in East Brad- 
ford Twp. It has been frequently seen along Buck 
run during the breeding season, and may have 
nested, though but a single male has been taken in 
perfect nuptial plumage (Wilson MS.). 
38. Herodias egretta Egret, “white crane.” Strag- 
gler from the south. Barnard states that it is sel- 
dom found. Warren notes a capture in July, 188: 
(Bds. Pa., 1890, 60). One was reported shot out 
of a flock of seven, near Kennett Square, July 10, 
1902, by C. J. Pennock (Cass., vi, 16), and a male 
(No. 771, coll. F. L. B.) was taken along Darby 
creek near Berwyn, July 26, 1902 (Wils. Bull., 40, 
109). Another was observed on the Brandywine, 
near West Chester, for two weeks during the sum- 
mer of 1911, by Mrs. H. P. Brinton, and probably 
the same one was seen near Sugar’s bridge, July 26, 
same year, by Miss $. C. DeHaven (Cass., xvi, 45).
