124 ^^^ WORLD'S BIRDS. 



North America. Their nests vary, being usually open, 

 but sometimes domed ; the well-known Tailor-bird 

 (Suforia sutoria) and others which sew leaves for a 

 nest-bag belong to this group. The Gold-crests 

 [Regulus) are sometimes placed in a separate family. 



The tree- and bush-haunting Warblers, like our 

 familiar Chiff- Chaff (Phylloscopus tristis) and Blackcap, 

 for instance, seldom come to the ground, and are 

 eminently migratory, few breeding in the tropics. But 

 there is a large group of short-winged, strong-legged 

 Warblers resident in warm climates, which have much 

 more terrestrial habits, and grade into the Babblers. 



The Tailor- bird above-mentioned is one of these, 

 and is the most familiar Warbler in the East. It is of 

 about the same size as a Wren, and olive-green with a 

 chestnut cap. This species has a loud note, but no 

 noticeable song ; many Warblers, however, are remark- 

 ably good songsters. f 



Wattled Pittas (PhilepittincB) , of which there are only 

 two species — Philepitta jala, black in the male and olive- 

 green in the female, and P. schlegeli, in which both sexes 

 are green and yellow, with the male's head black — 

 are confined to Madagascar, where no true Pitta is 

 found. They differ from the true Pittas by having 

 separate scales at the back of the shank, while the males 

 have a wattle over the eye. They keep more to the 

 trees than the true Pittas, which mostly live on the 

 ground. 



Waxwings [AmpelincB) are a curious group containing 

 only a few species, found in Europe, Asia and America. 

 They have small feet and a small bill with wide gape, 

 but unlike most other birds so distinguished, are mainly 

 frugivorous. Most of them are crested, and the best- 

 known species, the Waxwing [Ampelis garrulus) of the 

 northern parts of the world and the Cedar-Bird (A. 

 cedrorum) of North America, develop sealing-wax-like 

 appendages on the secondary wing-quills.
