I never saw a wild thing sorry for itself. A small bird will drop frozen dead from a bough without ever having felt sorry for itself.
Birds are indicators of the environment. If they are in trouble, we know we'll soon be in trouble.

Birds sing after a storm; why shouldn't people feel as free to delight in whatever sunlight remains to them?
The reason birds can fly and we can't is simply because they have perfect faith, for to have faith is to have wings.
Be as a bird perched on a frail branch that she feels bending beneath her, still she sings away all the same, knowing she has wings.
Use what talents you possess; the woods would be very silent if no birds sang there except those that sang best.
Birds have wings; they're free; they can fly where they want when they want. They have the kind of mobility many people envy.
