Small birds were active and useful right around our willow tree. We were delighted with this small fellow which did about one flight per minute, jumping from the branch to catch a fly.
Ten or more of such hunters were doing this for two hours, which is an impressive reduction of flies. And they do this several times a day, through all the summer days.
So in wintertime well feed them, thankful for the great work they did.
Please do the same!
