BIRDS OF NEW YORK STATE 31 



Dove, MouTning (continued) 



Call no. 



Nu DoM5 Two Young Birds Just Able to Fly, Perched on Stub of 

 Limb. Geneseo. (1910) Bailey 



The young birds will pose, as shown in the picture, for a 

 long time, waiting for the return of the adult. They are fed 

 about once an hour with partially digested food. Do they 

 resemble their parents? 



Duck, Black (Anas rubripes) 



This species is the commonest of the river ducks of the State. 

 It breeds sparingly throughout the State, chiefly in northern 

 portions. In the spring and fall this duck is found in small 

 flocks about the central lakes of New York. The black duck 

 is similar to the female mallard. How are the two species 

 distinguished ? 20-25

Nu DuB8 Flock of About 130 Flying Overhead. Near Mastic, L. I. 

 (September 1, 1912) Harper 



Owing to the protection given by the abolition of spring 

 shooting, black ducks in recent years have begun to spend the 

 summer in large numbers on Moriches bay. A part of a large 

 flock is here shown swinging over the brackish meadows border- 

 ing the bay. Note the short tail, the long neck held straight 

 out and the relatively long wings as compared with canvasbacks 

 and scaup ducks. 



See also Nu Ca92 and Nu DuS7. 



Duck, Scaup (Mania marila) 



Other names of this duck are the bluebill, broadbill and black- 

 head. It is a transient, found chiefly along the coast and large 

 inland waters. It breeds far to the north and migrates in winter 

 sometimes as far as South America. 18.5-20 



Nu DuS Single Adult Male on Water near Ice Stone 



The presence of ducks on our lakes and streams in winter 

 depends partly upon there being open water. They do not 

 remain where the surface is entirely frozen over. This bird was 

 doubtless weak from lack of 'food and allowed a very close 

 approach. The white flank feathers ordinarily conceal most of 

 the wing. The thin neck and head thrown back on the shoulders 

 are also signs of ill health. Compare Nu DuS5.
