FEMALE LONG-TAILED DUCK. 

 WILSON, PLATE LSI. FIG. II. EDINBURGH COLLEGE MUSEUM. 



THE female is distinguished from the male by wanting 

 the lengthened tertials, and the two long pointed feathers 

 of the tail, and also by her size, and the rest of her 

 plumage, which is as follows : length, sixteen inches ; 

 extent, twenty-eight inches; bill, dusky ; middle of the 

 crown, and spot on the side of the neck, blackish ; a 

 narrow dusky line runs along the throat for two inches ; 

 rest of the head, and upper half of the neck, white, 

 lower half, pale vinaceous bay, blended with white ; all 

 the rest of the lower parts of the body, pure white ; 

 back, scapulars, and lesser wing-coverts, bright ferrugi- 

 nous, centred with black, and interspersed with whitish ; 

 shoulders of the wing, and quills, black ; lower part of 

 the back, the same, tinged with brown ; tail, pale brown 

 ash, inner vanes of all but the two middle feathers, 

 white ; legs and feet, dusky slate. The legs are placed 

 far behind, which circumstance points out the species 

 to be great divers. In some females, the upper parts 

 are less ferruginous. 



Some writers suppose the singular voice, or call, of 

 this species, to be occasioned by the remarkable con- 

 struction of its windpipe ; but the fact, that the females 

 are uniformly the most noisy, and yet are entirely 

 destitute of the singularities of this conformation, 

 overthrows the probability of this supposition.

THIS species is very rare on the coasts of the 

 and Southern States, though not unfrequently found 

 off those of New England, where it is known by the 

 dignified title of the lord, probably from the elegant
