My observation of the flight of buzzards leads me to believe that they regain their lateral balance when partly overturned by a gust of wind, by a torsion of the tips of the wings. If the rear edge of the right wing tip is twisted upward and the left downward the bird becomes an animated windmill and instantly begins to turn, a line from its head to its tail being the axis. It thus regains its level even if thrown on its beam’s end, so to speak, as I have frequently seen them. I think the bird also in general retains its lateral equilibrium, partly by presenting its two wings at different angles to the wind, and partly by drawing in one wing, thus reducing its area. I incline to the belief that the first is the more important and usual method....
My business requires that my experimental work be confined to the months between September and January and I would be particularly thankful for advice as to a suitable locality where I could depend on winds of about 15 miles per hour without rain or too inclement weather. I am certain that such localities are rare.

Hawks are better soarers than buzzards but more often resort to flapping because they wish greater speed. A damp day is unfavorable for soaring unless there is a high wind. No bird soars in a calm.
The object of the tail is to increase the spread of surface in the rear when the wings are moved forward in light winds and thus preserve the centre of pressure at about the same spot. It seems to be used as a rudder very little. In high winds it is folded up very narrow.

I know what the caged bird feels, alas!
     When the sun is bright on the upland slopes;
When the wind blows soft through the springing grass,
And the river floats like a stream of glass;
     When the first bird sings and the first bud opes,
And the faint perfume from its chalice steals—
I know what the caged bird feels!

I know why the caged bird beats his wing
     Till its blood is red on the cruel bars;
For he must fly back to his perch and cling
When he fain would be on the bough a-swing;
     And a pain still throbs in the old, old scars
And they pulse again with a keener sting—
I know why he beats his wing!

I know why the caged bird sings, ah me,
     When his wing is bruised and his bosom sore,—
When he beats his bars and he would be free;
It is not a carol of joy or glee,
     But a prayer that he sends from his heart's deep core,
But a plea that upward to Heaven he flings—
I know why the caged bird sings!

 

Paul Laurence Dunbar

 

Pack, clouds, away! and welcome, day!
With night we banish sorrow.
Sweet air, blow soft; mount, lark, aloft
To give my Love good-morrow!
Wings from the wind to please her mind,
Notes from the lark I'll borrow:
Bird, prune thy wing! nightingale, sing!

 

Thomas Heywood

 

To say that Gannet City was busy would be an understatement. New York in the rush-hour would appear immobile in comparison. There were gannets incubating, feeding chicks, flirting, mating, preening and launching themselves into the air in effortless flight on their six-foot wings. With their creamy- white bodies, wing-tips black as jet and their orange-coloured nape and head they were impressive and immensely handsome.

With all humility, I think, "Whatsoever thy hand findeth to do, do it with thy might." Infinitely more important than the vain attempt to love one's neighbor as one's self. If you want to hit a bird on the wing, you must have all your will in focus, you must not be thinking about yourself, and equally, you must not be thinking about your neighbor: you must be living in your eye on that bird. Every achievement is a bird on the wing.
