Perhaps you’ve noticed birds doing strange things. I certainly have. Often they glance around afterwards to see if anyone is watching. One very silly-looking thing birds do is sun themselves. They will spread their wings to catch the most warmth, then go into kind of a trance.
They’ll put their heads to the side and simply melt in the sun. Often I’ve wondered about the safety of their balance.
But they always seem to come out of it okay. I’ve seen many different kinds of birds melting in the warmth, taking a sun bath. Usually it makes me want to do the same.
