I am sure You notice in the image above that the hummingbird is green sitting on a peach tree branch that is also green. The tiny bird looks like a leaf! This is Natures Grand Design to camouflage the living creatures so they blend in with their environment for safe hiding in plain sight. Your infostudy from Wikipedia explains camouflage in Nature. Your photstudy of September 9, features the birds in trees. It is nice to capture them in the trees but they are very difficult to see. If these birds do no want to be seen, they will be very quiet and still. There could be a hundred in the trees, but You would never see one! If they move or make one of their noises, You can spot them hanging out. Below are a few entries from the Google Search Index regarding hummingbirds and camouflage. Once You learn to spot birds in trees, they will become easier for You to see. Happy Hunting (for photo ops) and Enjoy!
The octopus ... seeks its prey by so changing its colour as to render it like the colour of the stones adjacent to it; it does so also when alarmed.—Aristotle.
When we see leaf-eating insects green, and bark-feeders mottled-grey; the alpine ptarmigan white in winter, the red-grouse the colour of heather, and the black-grouse that of peaty earth, we must believe that these tints are of service to these birds and insects in preserving them from danger. Grouse, if not destroyed at some period of their lives, would increase in countless numbers; they are known to suffer largely from birds of prey; and hawks are guided by eyesight to their prey, so much so, that on parts of the Continent persons are warned not to keep white pigeons, as being the most liable to destruction. Hence I can see no reason to doubt that natural selection might be most effective in giving the proper colour to each kind of grouse, and in keeping that colour, when once acquired, true and constant.—Darwin
