THEIR REPRODUCTION (NESTS) 261 



In the other groups of the Passeriformes we 

 have the^Broadbills (Eurylaemidae), in which the 

 nest is oval, the entrance being on the side near 

 the top, sometimes protected with a sort of porch, 

 or at other times prolonged into a tapering struc- 

 ture below. They are made of twigs, roots, grass, 

 moss, and leaves, and lined with green foliage, 

 which is frequently replenished when withered 

 as is also the case, by the way, with some of the 

 Birds of Prey (the Eagles and Buzzards, &c.), 

 and placed suspended from drooping branches, 

 often over water. The Pittas (Pittidae) are mostly 

 ground builders, and make globular nests, with a 

 side entrance of twigs, roots, grass, moss, and 

 fibres, in some cases cemented with mud. There 

 are several types of nest amongst the Tyrant 

 Birds (Tyrannida). These are made of twigs, 

 grass, moss, wool, and hair (sometimes such ab- 

 normal materials as rags, paper), felted in some 

 species with lichens and cobwebs, and are either 

 cup-shaped and open or domed. They are 

 usually placed in trees or bushes. There is no- 

 thing specially remarkable about the nests of the 

 Manakins (Pipridae), but in the Cotingas (Cotin- 

 gidae) there are several types of exceptional 

 interest. The Cock of the Rock (Rupicola) 

 makes a nest of mud and twigs, lined with moss,
