Humming-Birds. 207 



yet it is precisely this formless cloud on which the 

 glittering body hangs suspended, which contributes 

 most to give the humming-bird its wonderful sprite- 

 like or extra-natural appearance. How strange, 

 then, to find bird-painters persisting in their efforts

 is a delusion and a mockery. 



Coming to the actual colouring the changeful 

 tints that glow with such intensity on the scale-

 the Bpei'ra, gemmed with dew and touched with 

 rainbow-coloured light, has never been and never

On this subject one of the latest observers of 

 humming-birds, Mr. Everard im Thurn, in his work 

 on British Guiana, has the following passage:

 peculiar and glittering colour when the light falls 

 upon it from a particular direction. A true repre-

 somewhat sombre colours, except just at the one 

 point which, when the bird is in the position chosen
