The value of old Woodpecker cavities
This cavity in a telephone pole near my home in Utley, Texas is about 20 years old. In that time it has hosted breeding Red-bellied Woodpeckers, Eastern Bluebirds, Great Crested Flycatchers and the hybrid form of Tufted X Black-crested Titmouse called Dixon's Titmouse. This year the titmice once again have rented it after last year's Bluebirds, which seemed to have suffered a nest failure.
I have once seen a Texas Rat Snake half in and half out of the cavity. They can climb anything they can get a grip on.
Such holes are extremely important to your local cavity nesters and I highly encourage you to safeguard them. Consider them an asset. This hole is almost big enough now to host a roosting Screech Owl.
