Still just one second clutch growing, Four nests at egg stage

I went back by bike to check the known nests on the south side. No development there, all four had eggs, But at least no eggs were broken.

The North side nest is coming along fine, you can easily count four chicks.

Interestingly, with eyes closed, the birds sense more light. The box would not open otherwise, so not sure this is safe to be poking a bill out.

A bit of video

The wren next door (male) has not bothered Box 16 since he now has his own eggs to guard. House wren eggs are very small and brownish.
