Herons. Brazil boasts of a large number of magnificent herons. The Soc6 is 

 Ardea cocoi, the Soc6-y, Ardetta erythromelas ; Garga azul, Florida coe- 

 rulea. The Silver Heron or Egret (Gar9a real) has been terribly persecuted 

 in South America, in order that women may decorate their hats with its 

 feathers or aigrettes. A few dealers are enriched, a number of women wear, 

 for a short time, what they believe to be an adornment, and a living 

 creature of dazzling loveliness is destroyed for ever. In the more sparsely 

 inhabited regions of Brazil the following herons are found: the Night 

 Herons (Taquiry), Nycticorax tayazuguira, the Bittern, Reed-drummer or 

 Socoboi, so called from its roaring, bull-like voice (Tigrisoma lineatum), 

 and the curious Boat-billed Heron (Cancroma cochlearia). The family of 

 the Storks is also well represented : for example, by the Tuyli-yii (Tantulus 

 loculator) and the Jabini (Mycteria mycteria) with black head and rosy 

 collar, but otherwise white. The Brazilian Stork (Cegonha) is like our Ger- 

 man Stork, but larger (Euxenura magoary). The Red Ibis of the Amazon 

 is one of the loveliest birds on earth. 58, 119, 180

Hornets. The large Black "Cavallo do cae" is Pepsis albomaculata ; P. pertys is

Hudii, Momotus momota, a fine gaily-coloured bird, in form resembling our 

 Magpie, but with a toothed bill. Another species (M. microstephanus) has 

 a peculiar habit of sitting quite still, but the long tail-feathers, blue and 

 green, and rimmed with black, move constantly to and fro, about once 

 every second, so that it is pertinently called "the Pendulum Bird," Passaro 

 pendulo. 196
