Top Photo: Eastern bluebird eggs.

All of the nest boxes are empty except one.

The Cow Pasture nest box fledged its six bluebirds last week, to the day.

The Explore the Wild nest box still has a bluebird nest within but has not been added to since March.

The nest box at Into the Mist is empty.

As we approached, a house wren flew from the nest box on the east side of the parking deck. Inside the box was a partially constructed bluebird nest with a sprinkle of feathers on top. Who will, if anyone, use this nest box for their final nest of the season?

On the west side of the deck there was no change. The twigs placed in the box by a house wren weeks ago remain untouched.

The Butterfly House nest box is empty.

So, we have five unused nest boxes and one which is questionable. We’ll keep an eye on the Parking Deck East nest box for next week’s inspection.

Not related but interesting

The Columbidae formally known as rock dove, currently know as rock pigeon (Columba livia), and known by almost everyone alive simply as pigeon, is nesting on a ledge in the parking deck. This is this pigeon’s second brood in the parking deck this season.

Not a native species but well established here and on nearly every continent in the world. These birds were historically, and still are, found along rocky cliffs, caves, deserts, and mountians in their natural habitat. They have adapted well to urban, and sub-urban, life.
