Text Appearing Before Image:
Woodcock on NestA protectively colored bird which, relying on its color to escape detection, may some-times be touched before it takes wing.
Text Appearing After Image:
Black Skimmek on NestA conspicuou:sly colored bird which is so shy that it leaves its nest at the first indication of danger. BANNER MARKS 95 value of any color scheme or pattern of marking is active only whenthe animal bearing it is at rest. Without regard to color, movement atonce reveals, and bearing this in mind, the action of a bird in the pres-ence of danger is a supreme test of the protective or non-protectivevalue of its colors. If the bird is wary and can be approached only with difficulty,we may feel assured that it realizes its conspicuousness and conse-quently it rehes for safety on its watchfulness and its wings. But ifthe bird attempts to hide and flies only when convinced that it has beendiscovered, then we may beUeve that it relies primarily on the natureof its coloring to escape observation, when we are evidently justifiedin assuming that its colors are truly protective. Compare the colorsand actions of such wild birds as Gulls, Terns, Skimmers, Ducks,Geese, Cormorant
