of from 3,000 to 5,000 feet. The specimens taken were shot among 

 shrubbery on the edges of the forest, where they were feeding on 

 flowers. Its true habitat is, however, in the forest.

Confined to the forests of the Caribbean lowlands, from Panama to 

 Nicaragua. This bird is nearly always to be found in patches of wild 

 cane or "Wild Plantains," which are so abundant in the Caribbean 

 lowlands, its chief source of food being the blossoms of these plants. 

 It is usually found in company with Glaucis hirsuta, Phaethornis 

 longirostris and Agyrtria amabilis. 



On March 25, 1904, I found a nest of this species on the beach of 

 the Sicsola River. It was placed in a thorny shrub on a low gravelly 

 beach, the nest being about five feet from the ground. It was con- 

 structed almost entirely of vegetable down, adorned on the outside with 

 lichens, moss, and a few fragments of wild cane blades, all held together 

 with spider-webs. The nest measured: outside depth, 1.5; width, 

 1.75 ; inside depth, .65 ; diameter, 1.00 inch. It contained two fresh 

 eggs, of the usual elliptical form, which measured i3.5Xq;i3Xq mm.
