Ornithologists estimate that about half of all migratory North American songbirds die annually.
Nowadays it is difficult to believe that folks did not always believe ruby-throated hummingbirds migrated. However, unbelievably, it would be safe to say that during the 1600s it was indeed the prevailing belief among the early colonists.
There is no better proof of this than the Pennsylvania Cylopedia published in 1651. This reference book states the lives of hummingbirds ended when the flowers stopped blooming in the fall. Faced with a lack of food, hummingbirds would then simply thrust the sharp bills into the trunks of trees. Here they would remain motionless throughout the entire winter. Once winter eased its frigid grip on the land and the rejuvenating rains of spring drenched the land, hummingbirds would miraculously spring back to life and fly away.
Whenever I read such a bizarre story, I cannot help but wonder how such a belief surfaced. Obviously, no one has even seen a hummingbird overwintering with its bill stuck in a tree.
Have you ever found a beautiful spiderweb one evening and returned the next morning to admire it in the sunlight only to find that it had mysteriously disappeared? When you have such an experience, you cannot wonder what in the world happened to this remarkably structure. The answer to this mystery is perhaps as odd as the disappearance of the web itself.
Surprisingly, in many cases, the web is simply eaten by its creator. If that is the case, you might ask yourself, “Why in the world would a spider eat a web it only used for a few hours and required a lot of time and energy to fashion?” Part of the reason is webs lose their stickiness. As a result, they hapless insects that would normally find them stuck in a web are able to struggle free before the spider can dispatch them. Also, if a spider eats its own web, it recycles some of the energy and protein used to spin the sticky strands used to weave its beautiful and deadly web. In addition, it ensures that each night it is using a fresh, highly efficient web.
The house sparrow has a distinction shared with few other birds. Believe it or not, this common bird is represented in an Egyptian hieroglyph. This rarely used hieroglyph was used to mean narrow, small, or bad.
If you have ever been disappointed with an attempt to take a great close-up shot of a butterfly or flower, I have a suggestion that may help. This tip is especially helpful in eliminating shadows and enhancing the bright colors of your subject.
Begin by setting your camera on the Program mode. On my camera it is represented by the letter P. I then pop up the camera’s built-in flash and snap the picture.
The result is I eliminate any shadows that may be shrouding part or all of my subject. This also makes my subject seem to pop out from the background.
One thing to keep in mind is you need to be fairly close to your subject since most of these small flashes don’t effectively illuminate subjects more than six or so feet away.
In the world of the ruby-throated hummingbird, males do not assist the females in nest building, incubation of the eggs, or feeding the young. To the contrary, although males are sometimes seen in the company of females until eggs are laid, their attraction for one another wanes shortly after mating.
