On arriving at its winter abode, it takes up its residence 

 in the shrubberies and gardens of the Indian cottages, says 

 Mr. Bonelli. The hill-side of the neighbouring country, clothed 

 with the indigenous trees and shrubs, also affords it a fit place

 that may be best adapted to afford it security. The eggs are 

 two in number, and oblong in form, of a pure white, half an

The blue-tailed sylph has a wide range along the temperate 

 regions of the Cordilleras. The genus of sylph to which it 

 belongs is among the most beautiful and graceful in form 

 of the hummin^'-birds. The bodv is of a bronzed u'rcen, and
