THE BIRDS OF NORTHERN THAILAND 53 



mouth plumbeous; the feet and. toes plumbeous-gray, darker at the 

 joints; the webs and claws slaty. 



The pintail may be known in flight at a great distance by its rakish 

 build, its slender neck, and, in the case of the full-plumaged male, by 

 the greatly elongated, pointed tail feathers (but such males seem to 

 occur with us only rarely) . 



The drake has the whole head umber-brown ; the upper side of the 

 neck, the upperparts, and the sides of the body gray, finely vermicu- 

 lated with blackish; the underparts white, the white of the under- 

 neck extending as a white stripe into the brown on each side of the 

 head; the under tail coverts black; the long, pointed scapulars brown- 

 ish gray with wide, black shaft streaks ; the speculum glossy bronze- 

 green, edged above with a dull rufous stripe and below by a white 

 one. The duck has the upperparts generally dark brown, barred 

 and speckled with white; the underparts buffy white, barred and 

 streaked everywhere with brown. 



ANAS PENELOPE Linnaeus 



Eurasian Wigeon 



[Anas] Penelope Linnaeus, Systema naturae, eel. 10, vol. 1, 1758, p. 126 ("in 

 Europae maritimis et paludibus" ; type locality restricted to Sweden, apud 

 Hartert). 



Three or four examples of this distinctively marked species were 

 seen by me with a flock of Anas acuta, at a woodland pond near Ban 

 Pa Muat (north of San Sai Luang), November 23, 1936, but I was 

 unable to take a specimen. The wigeon may occur in winter any- 

 where in our provinces in the same localities as the pintail. 



The drake has the crown buff, the rest of the head and neck chest- 

 nut, the throat more or less marked with black ; the upperparts finely 

 vermiculated black and white (gray in the field) ; the breast vina- 

 ceous-pink; the under tail coverts black; the remaining underparts 

 pure white ; a large shoulder patch pure white ; the speculum metallic 

 green, edged above and below with black ; the underwing gray. The 

 duck has the plumage generally dark brown, the feathers edged with 

 rufous, gray, and buffy white; the breast and abdomen white; a dull 

 brown speculum, edged above by buffy white.
