A Black- Capped Chickadee started this nest in the Bluebird box back in April. You can see the moss base. House Sparrows and House Wrens tried to take it over. I don’t know which bird has added all this extra material on top…any ideas? No eggs visible. 5-21-23

Whose Nest?

Black-Capped Chickadee moss base 5-21-23

  1. Caleb Koser says:

    House wrens?

  2. Texas Bird Family says:

    If the wren is nesting than it is most likely the wren’s material.

  3. Holly Grant, Project Assistant says:

    House Wrens use only small twigs in their nests. This soft material could be the start of a mouse nest, or from a titmouse or chickadee.

  4. Paula says:

    Very interesting…I saw the House Wren fly in there yesterday. I’ll keep checking…very odd.
    Started out as a BC Chickadee nest, then House Sparrows invaded then House Wrens. Never put up boxes before.

    Just checked two House Wren eggs…5-22-23

  6. paula says: husband says black-caped chickadee eggs. Eggs very small…5-22-23

  7. Paula says:

    There are two brownish red small speckled eggs in the nest…they were kind of hidden.


  8. Paula says:

    Could very well be. Also think there are spider egg sacs in there as well…typical of House Wrens. Plus a wren was the last bird observed entering box. 5-24-23
