House Wren Nest Photo

Take a peek in a House Wren's nest box:

house wren nest

Notice the multitude of twigs!

There are several clues this was a House Wren's nest.

One - there are many twigs.

Two - spider casings in the nest. Those are the tiny, cottony white patches you see.

House Wrens will force away other cavity nesters from their territory. They are native birds.

The male filled the box with twigs. The female did not build the soft nest or nest in it. They occupied another box in the area. The twigs discouraged other birds from using this box.
