136 TIMALIIDJE. 



Subfamily TIMALIINiE. 



This subfamily, as now constituted, contains Oates's Crateropo- 

 diiice and the Timaliince,, which 1 find quite impossible tu differ- 

 entiate by any satisfactory character one from the other. 



The great majority of the Timaliince are \ery gregarious and 

 go about in flocks of considerable size, a few consort in small 

 liocivs, whilst fewer still are only found singly or in pairs. They 

 feed principally on the ground or in bushes and long grass close 

 to it, but some of them also haunt trees in their quest for the 

 insects which form their main diet. Some of tlie genera comprise 

 birds as noisy as any known, whilst others are birds with 

 sweet notes or are silent. The most prominent characteristics 

 are the very powerful legs and the weak, rounded wings. The 

 head is frequently fully crested, and is generally covered with 

 somewhat erectile feathers even where there is no definite 

 crest. The bill is of almost every conceivable shape. In 

 habits they are non-migratory, though some of the hill forms 

 move up and down the hills under climatic stress and, whilst 

 some species are very bold and haunt freely tiie vicinity of 

 villages, others are among the most shy. 



In ttie following key an attempt has been made to discriminate 

 berween the genera in a way which will be easy for the field 

 naturalist to work out; size ^nd plainly visible features in con- 

 struction being made use of.
