Wrens are notorious for multiple nests. There's different thoughts: One is the male builds in several locations to impress the female. If she likes a chosen spot, she takes apart his nest and starts over. Others say, the male wren builds a bunch to hinder other birds from nesting to decrease competition for food.
We remove the house wren's dummy nests. The males also go around pecking holes in eggs and killing new young, so we do not encourage them by leaving all the dummy nests. It's not too many.
Meadowlark sings! I haven't heard him in a few days. He called over some Rusty Blackbirds and Kessie (the female Kestrel), so that makes a great day! Other than that we have sun (a delight to see) and strong westerly winds. I was briefly in the prairie patch, but no birds. Or they were hunkered down and silent. I pulled out some weed grass and put that in the feeding area. The little birds will eat right from the stalks.
