Habits. According to Schomburgk (Reis. Cxuian, iii. p. 707, 

 no. 189) this beautiful species is only met with in the open woods, 

 where it hovers round the flowerinor trees and buslies. When 

 flying it spreads its tail like a fan, and at tne same time flicks 

 it up and down. This bird is not common in British Guiana. 



Schomburgk, under the name of Trochilva aurwulatus (Reis. 

 Guian. iii. p. 707, no. 190), states that these birds live in the open 

 and light part of the woods, where they swarm round f]ow<Ming 

 trees and Scitaminoon.

 remarks (Timehri (2) v. p. 99): — "The Fairy Huiiiiniiig-l)ird> 

 (ffeiiofjirlx nurifus) are often seen about the town.
