4 fledged safely, 10 more eggs to hatch

These four young left the nest the past 5 days or so and there are now 10 more bluebird eggs to hatch

Two eggs in Box 16 remain on the North, saw one parent. Brave effort next to wrens.

On the South side there are 5 eggs and 3 eggs in two boxes. These two raised four young and now have 5 more eggs:

Swallows remain around boxes, a few young ones still peeking out of the hole. In a week all will have fledged. Box one South side fledged 5-6 swallows, one did not make it.

WRENS

On both sides at least one pair of wrens is active. Box 14 on the South side is hard to access at this time, but it was claimed by wrens a week ago. Box 13 had grown swallows 5 days ago. The wrens will not harm them, they are smaller themselves. But as soon as the swallows left, 3-4 days ago, a male wren filled the entire box with sticks. They already have the neighboring nest box!

Evicting is not something I like to do so I never take out built nests. But if you get to the box before the wrens lay eggs, I think it's fair enough to take sticks out. The role of a male house wren is to fill every hole in his neighborhood with sticks, whether they use the box or not later on.

Another option is to pull up the box with wren sticks and move it to a different location, further away from the trees.
