state. Only five, of over seventy, naturalists and collectors, who have 
kindly sent me lists of birds found in the different counties of our com- 
monwealth, seems to have observed this species. Their reports are sub- 
stantially as follows : Dr. John W. Detwiller, Bethlehem, strag-g-ler in 
Northampton county ; Dr. W. Yan Fleet, Renovo, straggler in Clinton 
county ; D. Frank Keller, Reading, accidental visitor in Berks county. 
Prof. H. Justin Roddy, in a letter sent to me from Landisburg, July 15, 
1889, says : ''Ardea coerulea is a rare breeder (Perry county). Found a 
set of eggs June 20, 1885, near the base of Mt. Dempsey.”

The Green Heron is known by a variety of local names, some of which 
are much more expressive than eleg'ant. This bird, the most common 
and abundant of all our herons, is found throug*hout the state, frequent- 
ing- rivers, streams and ponds. It arrives in this section occasionally as 
early as the first week in April, from the southern states, where it re- 
sides when the chilling- blasts of winter have frozen over our streams 
and marshes. This species sometimes breeds in small companies ; g-en- 
erally, however, but two or three pairs are found nesting- tog-ether. The 
nests, built of sticks and twig-s, are placed in low bushes or small trees 
adjacent to a stream or i^ond. The nests frequently are built in apple 
orchards. Indeed, the larg-est number of nests that I ever found in one 
locality was in an apple orchard along- the Brandywine, where for several 
years some twenty-five or thirty of these birds annually resorted. While 
it is true that I have found these herons breeding- in small numbers with 
the Nig-ht and Great Blue Herons in Pennsylvania, and also in Florida 
in company with the Little Blue, Louisiana and Snowy Herons, and 
even sometimes in the colonies of Water Turkeys and Cormorants, I
