THE BIRDS OF NEW JERSEY. 87 



148 Marila marila (Linnaeus). 

 Greater Scaup, Broadbill, Bluebill. 



Adult male. Length, 18-20. Wing, 8.25-9. Entire head, neck, breast and 

 fore part of back, as well as rump, wings, upper and lower tail-coverts and 

 tail, black ; head glossed above, and on the sides with green ; throat with 

 purple ; scapulars and middle of back vermiculated with black and white ; a 

 white wing speculum ; abdomen, white, vermiculated posteriorly and faintly on 

 the sides with black. 



Adult female. Above, dull black ; finely speckled with gray on middle of 

 back, becoming reddish-brown on back, sides of neck and breast ; a white area 

 on side of head next to bill, involving forehead and chin ; abdomen, white, be- 

 coming brown on sides and dusky posteriorly ; a white wing speculum. 



Abundant transient and winter resident; the most plentiful species 

 on Barnegat Bay, where it remains so long as the water is open, re- 

 turning when the ice disappears. Occasional on the Delaware and at 

 Princeton. This species is so generally confused with the next that it 

 is difficult to determine which is the more plentiful. According to 

 Mr. Chapman/ for the vicinity of New York; Mr. Scott, 2 for Long 

 Beach, and Mr. Laurent, 3 for Five Mile Beach region, this species is 

 the more abundant one. Occurs from October to April 15th, while 

 Mr. Scott has seen flocks as late as May 1st. 



149 Marila affinis (Eyton). 

 Lesser Scaup, Creek Broadbill. 



Adult male. Length, 15-16.50. Wing, 7.50-8.25. Similar to the preceding, 

 but head glossed with purple on top, and with sides of the body strongly vermic- 

 ulated with black and white like the back. 



Adult female. Differs only in size from female Greater Scaup. 



Common transient or winter visitant. Occurs at the same time and 

 in the same way as the preceding, though probably not so plentiful. 

 Usually confused with it.
