I was out a Turtle River State Park on Sunday The park has an ASY male in the same unit as last year. I don’t know if they have more. We drove by your place and your colony is really nice this year.

I have a possible renesting pair that had 2 eggs June 19th, 1 egg on June 20th, and no eggs June 23rd. Today they had 3 eggs all buried in the nest… Did I miss count? I rearranged things a bit and will recheck tomorrow. It is a SY female nest, so she may not know how to keep a nest.

121 eggs laid
77 live young
25 eggs (un-hatched)
19 eggs (discarded infertile lifeless)
24 breeding pair
5 bachelor pads (leaves with no eggs)
5 empty units (no leaves)
1 pair possible renesting attempt (don’t know for sure)
18 English House Sparrows dead
