That's what those birds are! We have them nest on the sides of the road next to the fields. The farmers are requested to not mow certain areas until after August, so that nests and habitats aren't compromised. Thanks for the pics. We had a HUGE thistle in our iris bed and just as my husband was going to cut it out, he spotted a wren nest right near the stem about a foot from the ground. Smart bird. The eggs were so tiny! Obviously we left it until the fledglings left the nest.
