      I have a nest box where hosp destroyed bb eggs in a grass nest that was created.
      Two days later several inches of a jumble of twigs were placed on top of the grass nest.
      The twigs are 1/8″ in diameter and all mixed up, not resembling a nest.
      Is this the work of a blue bird, or some other bird trying to lay claim?
      I have seen this twig mess in two houses now.


      Sounds like the HOSP. A House Wren builds a trashy nest also but not with that big of a twig.

        Sounds more like a house wren to me – have you seen or heard a wren around? I have watched house wrens go in & out with their twigs & sometimes they (twigs) are so long they cannot get them in the hole without going in at an angle. Have never seen (or heard) about HOSP bringing in twigs – only junk, feathers, & coarse grass & weeds. BUT different areas may be different?? Here is a link from the Sialis website showing a dummy wren nest.


          I believe you nailed it. House wren.
          The Sialis piece described what I have to a “T”.
          Controlling nature seems like an impossible task.

            House Wrens build dummy nests exclusively with small diameter twigs. When a male is trying to attract a mate he fills all the cavities he can find with twigs. If a female accepts one of them, he’s a lucky guy. The acquisition of a mate doesn’t mean the end of his attacks on all the other nests in his territory. He continues with this behavior in an effort to protect the food supply. I never, ever let them succeed here because that would just mean more wrens.

            And, no, you can’t control nature. All you can do is offer your best protection.
