The Columbian Thornbill 

 is an inhabitant of Santa Fe de 

 Bogota, and is remarkable for its 

 adherence to the more temperate 

 regions of that locality. It never 

 seems to ascend to the hills, but 

 ])refers remaining in the plains or 

 in some of the valleys where it 

 can find the greatest abundance 

 of food. It appears not to fre- 

 quent the tops of trees, as is often 

 the case with Humming-birds, 

 but contents itself with the low 

 tlowering shrubs of the plains and 

 valleys. The colour of this bird 

 is golden-green on tlie upper 

 parts, changing into a warmer 

 hue on the upper tail-coverts. 

 Below, it is dull green, with the 

 exception of a remarkable tuft or 

 beard which hangs from the chin, 

 and which is light green towards 

 its base and purple-red towards 

 its extremity. The wings are 

 purple-brown, the tail brown with 

 a bronze gloss, and the under tail- 

 coverts brown-yellow. The female 

 resembles the male, but has not 

 the flame-like mark on the throat. 

 The total length of this species is 

 between five and six inches. 



There are several species of 

 Thorubills, among which may be 

 noticed Herran's Thoenbill 

 {lUimiipliomicron Herrdni), a bird 

 which is remarkable for its broad 

 purpletail and the snowy white tips 

 of the three exterior feathers. All 

 the Thorubills possess the curious 

 beard-like appendage to the chin. 



At the right-hand lower corner of the engraving on page 223, will be seen a curiously 

 formed bird, remarkable for its loug slender crest and the elongated feathers of its tail. 

 Tliis is the Popelaire's Thorntail [GouUia Popelalrii). This beautiful little creature 

 inhabits Peru and Columbia, and is found in the most elevated regions of that locality. It 

 is a very quick flier, but there is little known of its habits. 



In the adult male, the crown of the head, the shorter feathers of the crest, together 

 with the face and throat, are light golden green, and the long slender feathers are black.
