House Wrens put spider egg sacs in their nests. When the spiderlings hatch, they eat any mites that may be bothering the baby birds. House Wrens love it here at Spider Acres!
These birds all have more than a million sightings on eBird, what were you thinking submitting them to a dumb niche hipster poll??? Joking aside, these birds were definitely too popular to get into the poll itself. Please vote for your favorite here!
The House Wren has laid egg six this morning. She has been adorning the nest with feathers that she found around the property, and I like how her color choices match the walls.
The box is also a 6 inch diameter PVC box and I added two holes in Bluebird size and use a shrout with different hole sizes to adjust the box when necessary. The two holes provide better air flow and in the case of Bluebirds, might help the birds to escape a House Sparrow attack.
