BIRDS OF A WASHINGTON CITY DOORYARD 3 



1. Nycticorax nycticorax naevius. Bla^k-crowned Night Heron. 

 This species was observed on_lhree occasions flying over — May 



18, 1914; September i, 1917; and January 17, 1918. 



2. Butorides virescens virescens. Green Heror. 



Noted on four occasions — May 13, 191 2; May 18, 191 7; August 

 21, 191 6; and August 24, 19 14. 



3. Cathartes aura septentrionalis. Turkey Vulture. 

 Although the Turkey Bjzzard is of common occurrence about 



Washington, we have actually seen it at this place in the city only 

 three times — February 28, 1915; September 24, 1916; and Septem- 

 ber 23, 191 7; on each occasion sailing over high in the air. 



4. Tinnunculus columharius columharius. Pigeon Hawk. 

 One seen flying over on February 20, 19 16. 



5. Cerchneis sparveria sparveria. American Sparrow Hawk. 

 This bird breeds in the cornices of buildings in our section of 



the city, and we have frequently seen it at our place, either flying 

 over or perching on the very top of the large silver poplar tree 

 in the yard. It has been noticed most often in April, May, Septem- 

 ber, and October, the earliest date being April 11, 191 5, and the 

 latest, November 9, 1915. 



6. Colinus virginianus virginianus. Bob -white. 



This was one of our most interesting and most unexpected 

 visitors. Once a single bird, on a date not recorded, came into the 

 back yard and perched on one of the fences for a considerable 

 time. On September 21, 1913, two birds were heard calling from 

 the trees in the street in front of the house ; and on May 6, 19 14, one 

 was heard in the area back of the house. There seems to be little 

 attraction for a Bob-white in the city, a place so very different 

 from its native heath. 



7. Porzana Carolina. Sora Rail. 



One individual heard calling in flight over the house on the 

 night of September 21, 191 7. 



8. Tringa solitaria solitaria. Solitary Sandpiper. 



Noted on two occasions flying over — May 13, 191 2, and May 

 21,1917. It is of interest to mention that the latter date equals the 

 latest previous spring record for the species in the vicinity of 

 Washington. 



9. Bartramia longicauda. Upland Plover. 



The Upland Plover is now one of the rare birds about Wash-
