 the rock is exposed to the sun, the heat generated

 such an exquisite contrast of colour as is hardly 

 to be found even among the fauna of the tropics. 

 Its head, neck, and back, are soft ash-gray, and 

 when its wings are closed you would hardly dis-

 but in an instant, as it begins half to climb and 

 half to flutter from crevice to crevice, you will 

 see the brilliant crimson of its lesser quill-feathers 

 standing out, not unlike the underwings of a well- 

 known moth, against that delicate gray. Its bill 

 is long and slender, but strange to say, it is with-
