Tonight the moon is nearly at full moon and was visible in the early evening sky. When I went out onto the deck to check on it I discovered that there was a feint rainbow over the moon. I have never seen this before.
Right near the far right end of the rainbow there is a tiny speck that is a Welcome Swallow, flying high in the sky, hawking for insects. Amazingly these tiny birds fly at about thirty miles per hour, with their mouth gaping open, and catching insects!
