36 PROCEEDINGS OP THE 



from 2.30 p. m. to dark westward. To be more explicit, the 

 Crows used to roost at the river shore at Florence Heights up to 

 circa 1860-62, and gathered there from Jersey (eastward), but 

 whether other Crows came from over in Pennsylvania to this 

 roost I do not know. For as far back as I can trace, over a 

 century. Crows in this immediate neighborhood always spread 

 over Jersey in the forenoon, coming eastward, from the river or 

 from across it, and the afternoon flight was always westward or 

 towards the river. It was about 1860-62 that the Florence 

 Heights roost was destroyed, and then as I am told, the Pigeon 

 Swamp roost was greatly increased by the Jersey Crows joining 

 them. The great original roost was and a trace of it still is in 

 the Pigeon Swamp, near Bristol, Pa." 



Perhaps the "Pigeon Swamp roost" mentioned by Dr. Ab- 

 bott is the one here referred in Bensalem township, but we can 

 find no evidence of any roost in the Pigeon Swamp now or for 

 some years back. It is, on the other hand, possible tliat the 

 Crows crossing at Trenton go to the Davis Grove roost. 



Whether the five roosts here mentioned existed together or 

 whether the Davis Grove, Pigeon Swamp and Bensalem roosts 

 one or all owed their foundation to the breaking up of those at 

 Florence Heights and Hainsport we cannot say; but only two of 

 the five seem now to be in existence. 



4. Davis Grove, Montgomery Co., Pa. 



One of the largest and most important roosts. 



In 1886-7 a large number of Crows also roosted near War- 

 ringtonville on the farm of Isaac Warner, while others made 

 use of the hemlocks on the Almshouse farm at Doylestown. 

 These latter are probably mere branch colonies from the main 

 roost. So far as we can learn the roost is still in use and flights 

 from Doylestown and Fort Washington are directed toward it. 



6. South of Doimingtown, Chester Co., Pa. (?) 



The evening flight at Downingtown is south according to Dr. 

 Howard Y. Pennell, and this coupled with the northward flight 

 at West Chester would seeiii to indicate another roost some- 

 where midway between these places. No further evidence of 

 such a roost is in our possession however.
