THEIR REPRODUCTION (NESTS) 257 



members of the Passeriformes contained in the 

 group Oscines {conf. p. loi). Here also we find a 

 very similar diversity of structure in the nests, 

 not only in the various families but in the differ- 

 ent genera. In the Timeliidae, for instance, there 

 is almost every type of nest to be found, but 

 domed or otherwise concealed nests are very 

 prevalent. Warm linings, however, are not so 

 general, grass, dead leaves, fibres, moss, and 

 twigs being the usual materials. The Tailor 

 Bird (Orthotomus longicauda) makes a wonderful 

 nest ; selecting a broad leaf, and drawing the 

 edges together with fibres (which are actually 

 knotted), lining the cone thus formed with fine 

 grass and vegetable down. Some of the Aus- 

 tralian forms (as in Pomatorhinus) fabricate huge 

 domed nests of twigs lined with feathers, adding 

 to them a spout-like entrance, and placing them 

 at the extremities of branches. The Bulbuls 

 (Pycnonotidae) chiefly build somewhat flimsy 

 open nests, placing them in trees and bushes, 

 but in one genus (lole) they are suspended like 

 the Orioles. The Cuckoo Shrikes (Campepha- 

 gidas) and the Drongos (Dicruridae) also make 

 open cup-shaped nests, placing them in bushes 

 and trees ; so also do the Greenlets (Vireonidae), 



in many cases, however, slinging them like that
