Top Photo: Eastern bluebird eggs from previous season.

On the fourth week of nest box inspections there is one active nest and five empty nest boxes.

The Cow Pasture, Explore the Wild, and Into the Mist nest boxes are empty.

Last week the nest box on the east side of the parking deck held one bluebird egg. Today there were five eggs in the nest. There was no sign of an adult in the area so it’s not clear whether the eggs are being incubated or if there will be an additional egg deposited. Incubation doesn’t begin until the last egg is laid. This insures they will all hatch at the same time, or close to it.

The Parking Deck West and Butterfly House nest boxes both remain untouched.

So, we have one active nest (Parking Deck East) with five bluebird eggs and five empty nest boxes.

It’s still early in the season and anything can happen. Don’t miss it!
