 of remark, that males compose by far the greater portion  of the individuals observed  at this elevation, while  
 very few females are seen  there;  whereas in the lowlands this sex outnumbers  the other.  In March  a con-  
 siderable  number  are  found  to be  clad  in  the  livery of  the  adult male,  but without the long tail-feathers,  
 while others  possess  them  in various  stages  of development.  These  are,  I  have  no  doubt, males  of  the  
 preceding season.  It is also quite common  to find one of these lengthened feathers much  shorter than  the  
 other;  and in  their aërial encounters with each  other a tail-feather  is  sometimes displaced.  The wliirring  
 sound made by the rapid vibration of the wings of  the male  is  more slirill  than  that produced by those  of  
 the  female, and  indicates  the  proximity of  the bird  before  the  eye  lias  detected it.  The male utters an  
 almost  incessant  chirp, both while  resting  upon a twig and while  feeding  from  the flowers.  They do not  
 invariably probe the  flowers  upon  the wing,  but  may frequently be  seen  thus  engaged when  alighted  and  
 sitting with  closed wings;  and  they often  partially sustain  themselves  while  feeding  by clinging with  the  
 feet  to a leaf with  the wings  expanded  and vibrating.”.  .  .  .  When perched,  “ they usually sit  in  a nearly  
 upright  posture with the  head tlirown  somewhat  backwards,  the  beak pointing at a small angle above the  
 horizon, the  feet  almost  bidden  by the  body being  brought  into  contact  with  the  perch,  the tail  tlirown  
 somewhat forward under the belly,  and  the long feathers Crossing each other near their middle.” 
 Mr. Gosse States, that they do not confiue  themselves to any particular season for nidification, but that he  
 found  the nests 'most numerous  in June;  while Mr.  Hill considers  the  breeding season  to  be at its  height  
 in  January.  The  situation  of  the  nest  too  appears  to  be  very  various, Mr.  Gosse  having  found  one  
 attached to the  hanging fibre of the  root of a tree which  had  entwined itself  round  the projecting points of  
 an  overhanging  limestone  rock  in  a  deep  and  thickly wooded dell;  another stuck on a twig of a sea-side  
 grape-tree (Coccoloba), at about fifteen feet from  the ground,  the tree itself being so near to the water that  
 some of the branches liung over i t ;  another on  a hanging twig of a black mangrove-tree,  the twig passing  
 perpendicularly  through  the  side  and  out  at  the  bottom ;  and  another  on  a  twig  of  a  wild  coffee-tree  
 ('Tetramermm odoratissimum).  The nest is principally “ composed of silk cotton very closely pressed, mixed  
 with  the still more glossy cotton of an Asclepias, particularly around  the edge ;  the seed remaining attached  
 to some of the  filaments.  On  the outside  the whole structure  is quite covered with  spiders’-web, crossed  
 and recrossed in  every direction, and made to adhere  by some viscous substance, evidently applied after the  
 web was placed, probably saliva.  Little  bits of pale green lichen, and fragments of thin laminated  bark, are  
 stuck  here and  there  on  the outside  by means  of  the webs  having  been  passed  over them.”  The whole  
 forms  “ a very compact  cup,  l i  inch  deep  without,  and  1  inch  deep within ;  the sides about i  inch  tliick,  
 the inner margin  a little overarching,  so as to narrow the opening;  the total diameter  at  the  top  l i  inch.”  
 The eggs are of a long oval form,  and of a pure white,  save that when  fresh  the contents produce a reddish  
 tinge, from  the thinness  of  the  shell;  they are seven-twelfths  of an inch  long  by four-twelfths  of an  inch  
 hroad.  The above, adds Mr. Gosse,  is the usual “ form,  dimensions,  and materials of the nest.  Variations,  
 however, often  occur from  local causes:  thus  in one from a rocky situation only moss is used,  and the  base  
 is prolonged  to  a point;  one  now before me is wholly composed of pure silk cotton  bound profusely with  
 the  fiuest web, undistinguishable  except  on  the  closest  examination;  not  a  fragment  of lichen mars  the  
 beautiful  uniformity of  its appearance ;  others are  studded all  over with lichens and have a peculiar rustic  
 prettiness.”  That the chief food of the Humming-bird consists of insects, we havé abundant evidence from  
 examination of the stomachs of many species ;  they are usually sought for in the deep flower-cups, but that  
 they are also obtained by hawking in  the air, we learn from Mr. Gosse, who States that he has distinctly seen  
 “ the minute flies in the air, which  it pursued and caught,  and heard repeatedly the snapping of the beak.” 
 It will be seen  that I have drawn very largely from  the rich store of observations recorded by Mr. Gosse,  
 and much more miglit be extracted with  advantage, particularly a long and  most interesting account of the  
 various  attempts  made  by that gentleman  at  domesticating  this very lovely species,  for which, however,  I  
 must beg to refer  the reader to his  “ Birds of Jamaica.” 
 The male has  the  crown  of the  head  and  the  nape  deep  velvety  black;  upper  surface  green;  wings  
 purplish  black;  tail  deep  black, glossed with  green at the base ;  throat, breast and belly lustrous emerald  
 green ;  vent and  under tail-coverts bluish black ;  irides black;  bill coral-red,  the tip black ;  feet brown. 
 Total length,  10 inches ;  bill,  1 j  wing, 2f-;  tail, 7\ ;  tarsus, i. 
 The female has all  the  upper  surface green with a bronzy lustre,  deepening into brown on  the forehead;  
 wings as in the  male;  two centre  tail-feathers  bronzy green,  the  remainder  deep blue glossed with bronzy  
 green  on the basal portion of the external web,  except the  two  outer feathers on each side which  are  deep  
 blue  largely tipped with white ;  under  surface white,  the  tips  of  the feathers on the sides of the neck and  
 flanks glossy green ;  irides dark brown; bill reddish  brown, black at the edges and tip; feet brownish black. 
 Total length, 4± inches ;  bill,  1 ;  wing, 2^-;  tail,  l i ;  tarsus, i.
