Four Active Bluebird Nests in June

South Side

Box 12 nestlings June 17 (top) and June 19. They were quite sleepy but I could get three to open their bills a bit. In two days the pin feathers clearly broke through in the wings

There is a nest with eggs in Box 5 that had no eggs a week ago. 

House Wrens

There is one active male wren on the South side. These males fill up every hole with sticks to impress females. No eggs. 

Swallows

Two boxes have swallows  fully grown. If I opened the box, they would just fly out.
