migratory movement on the 18th and 19th and another on the 

 25th and 26th and on the 30th, which was a clear day, follow- 

 ing three days of rain. 



The first of these waves brought the Towhee, Tree Swallow, 

 Myrtle Warbler and Brown Thrasher; the second the Chimney 

 Swift, Black and White Warbler, Yellow-throat and House 

 Wren; and the last the Spotted Sandpiper, Whip-poor-will, 

 Ovenbird, Catbird and Wood Thrush. 



May was clear until the 13th, with an enormous migratory 

 movement on the 3d and 4th. 



The spring was noteworthy for the great number of rarer 

 warblers observed, notably the Cape May, Bay-breasted and 

 Wilson's. 



The autumn of 1912 was characterized by the great abund- 

 ance of Ked-breasted Nuthatches, which remained through the 

 winter and well into the spring at a number of stations. In the 

 autumn of 1913 came an unusual influx of Black-capped 

 Chickadees. 



A table similar to that prepared last year is appended show- 

 ing the number of days earlier ( + ) or later ( — ), by which the 

 1913 bulk-arrival dates for the Philadelphia district differed 

 from the average.
