More eggs! Only a single pair nested, but now more eggs

 The pair on the South side that raised three young left the box empty for a while. I checked that and the one next door. No swallows had taken that one all thru May. Since the box was cleaned and empty, they built a nest in the same box where two young died. This rarely happens, they usually move.

I have not seen the parents but once. This is the female.

I will check the box again about two weeks from now, as the pests in the prairie get worse now. I don't feel like walking much through grass. But in two weeks we should have partly grown young, probably eyes open but not much past that. If it goes long past that, I will check once in July.
