Curious things

Curious thing number one: If you put a buzzard in a pen that is 6 feet by 8 feet and is entirely open at the top, the bird, in spite of its ability to fly, will be an absolute prisoner. The reason is that a buzzard always begins a flight from the ground with a run of 10 to 12 feet. Without space to run, as is its habit, it will not even attempt to fly, but will remain a prisoner for life in a small jail with no top.

Curious thing number two: The ordinary bat that flies around at night, a remarkably nimble creature in the air, cannot take off from a level place. If it is placed on the floor or flat ground, all it can do is shuffle about helplessly and, no doubt, painfully, until it reaches some slight elevation from which it can throw itself into the air. Then, at once, it takes off like a flash.

Curious thing number three: A bumblebee, if dropped into an open tumbler, will be there until it dies, unless it is taken out. It never sees the means of escape at the top, but persists in trying to find some way out through the sides near the bottom. It will seek a way where none exists, until it completely destroys itself.
