riety of a bird of the same country, which is ash coloured above, 

 white beneath, with vestiges of grey undulations. (1) 

 We may also approximate to the Goshawks some American birds 

 with short wings and tarsi; the latter, however, reticulated. 



F. cachinnans, L. ; Nacagua, Azz.; Vieill. Gal. 19; Spix, III. 

 (The Laughing Falcon.) So called from its cry; white; the man- 

 tle and a band which extends from the circumference of the eye 

 to the neck, where it joins a corresponding one on the opposite 

 side, brown; brown and white bands on the tail. From the 

 marshes of South America, where it feeds on Reptiles and Fish.(2) 

 The name of Sparrowhawk, (Nisus, Cuv.) is generally appro- 

 priated to those whose tarsi are higher and scutellated; but the tran- 

 sitions from one division to the other are almost insensible. 



F. nisus, L.; Epervier Commun, Enl. 412 and4467; Naum. 19, 

 20. (The Common Sparrowhawk.) Coloured like the Goshawk, 

 but its legs are longer, and it is a third less in size. It is employ- 

 ed however by falconers. The spots beneath on the young bird 

 red and arrow-shaped, or like elongated tears the feathers of 

 its mantle are also edged with red. 



There are foreign species still smaller;(3) but there are some 

 also much larger. 



F. musicus, Daud.; Faucon chanteur, Vaill. Afric, xxvii. As 

 large as the Goshawk; cinereous above; beneath, and the rump, 

 white, streaked with brown; brown, varied with red, when 

 young. Found in Africa, where it pursues partridges and hares, 

 and builds on trees. The only bird of prey known that sings 

 agreeably.(4)

 Sparrowhawks. 



N. B. The F. cserulescens forms the genus Hierax of Vigors : the species with 

 two teeth, as the bidentatus, &c. or the Bidens of Spix, are the Harfagus of the 

 same gentleman.
