66 BLACK-THROATED AVAR15LER, 



very clear description. The bird is in its winter 

 plumage, and thus differs from my figure, which is in 

 its summer dress. 



"The upper part of the head, hack, and rump, a 

 beautiful clear yellowish olive green, more inclining to 

 yellow towards the rump; forehead, a broad stripe over 

 the eyes, and sides of the throat, very beautiful clear 

 yellow; from the beak to the eyes is a blackish stripe, 

 which is continued on the other side of the eye, 

 and terminates, or is blended with, the colouring of the 

 ear coverts. Chin, and front of head and neck, are

 belly, and under tail coverts are yellowish white, having 

 on each side two broad black stripes. 



Wing and tail feathers are black, with bluish ash 

 grey borders, which on the back of the wing become 

 almost white; greater wing coverts have broad white 

 tips, the smaller entirely white, by which two shining 

 white bands across the wing are formed. Both the 

 outer tail feathers are almost entirely white, having on 

 the outer web only a faint black stripe, Avhich is broader 

 at the tip, and towards the rump is almost lost in the 

 black shaft; the third tail feathers also have on the 

 inner webs a large white spot. Beak, feet, and iris, 

 brown black. 



The form of this little bird is elegant, though the 

 beak is rather strong in proj)ortion to the size of the 

 bird; the feet are somewhat feeble. The tail is almost 

 evenly notched; the outer j)air of feathers are rather
