1891, by the late C. C. Young of Brooklyn. Rare in mid- 

 winter. They are more common in November than any month. 

 Rare in the spring. 



57. Anas boschas. Mallard. 



Rather uncommon transient visitor. Oct. 3 to Dec. 24. 

 March and April. They occur in small numbers here, usually 

 in company with the Black Duck. 



58. Anas obscura. Black Duck. 



Common permanent resident. x\bundant in spring and 

 fall. At Montauk Point the nest containino^ eo-gs has been 

 found as early as April 5 (1905). 



An observing bayman, Andrew Chichester of Amityville, 

 informs me that he has many times taken specimens of the 

 Black Duck which show^ decided traces of hybridism with the 

 INIallard. One of these, sent me, showed distinct traces of both 

 parents; wrings and tail are those of the Mallard; back and 

 breast are like the Black Duck; the cheeks and sides of the 

 head glossed with green; the breast tinged with vinaceous. 



59. Anas obscura rubripes. Red-legged Black Duck. 

 Rather common winter visitor. It is largely confused with 



the preceding, but the more observing baymen and gunners 

 regard them as different (Braislin, Auk, xxi, 1904, p. 288). 



60. Chaulelasmus streperus. Gad wall; Gray Duck. 



A very rare or casual visitor. Giraud recorded it. INIr. 

 William Dutcher gives records of two or more examples (Aiik, 

 V, 1888, p. 173). One is contained in the Long Island His- 

 torical Society collection (Auk, x, 1893, p. 270). 



61. Mareca penelope. Europeax Widgeon. 



Casual. Several examples of this species have been taken 

 on Long Island. Giraud recorded a specimen, (Birds of L. L, 

 1844, p. 309), three were secured, in 1901, 1902 and 1903, at
