By Abbott H. Thayer V 



These various sketches of Flamingoes and Spoonbills show how wonderfully such birds match 

 or reproduce the colors of morning or evening skies to the eyes of the inhabitants of the water in 

 which thg^3|; wade— both their enemies, such as anacondas, alligators, sharks, etc., and such of 

 their prey aa can see them. 



Conmitinly, the bird's upper outline 'melts' into the sky, leaving the rest of his contour, seen 

 through the water, agitated and muddied by his feet, to be lost in the indeterminate color-mass of 

 the flock. Shaken and jumbled by the contmual agitations of the water, the image of the flock 

 retains, for eyes beneath the surface, only its color and its positioQ,, both of which coincide with 

 those of the dawn or sunset, (though on the other side of the heavens) or the flushed sky opposite. 



Through aU stages of twilight this living mass, seen against the less lighted parts of the sky, 

 blends into it, undergoing kindred changes of illumination, and when full Bunlight bathes it, its 

 lighted side blazes out into a perfect representation of the dawn or sunset itself, though in the 

 opposite quarter. In the case of the Red Flamingo the bird's legs, including its feathered thighs, 

 are purplish instead of orange-red, in keeping with thfe color-gradation of the sky, which is, at 

 these hours, commonly purplest at the lowest point, having its purest reds and oranges a little 

 higher up. Thus, each part of the bird has every possible opportwiity of matching its 

 backgirotuld.— A. H. T.
