I finally saw a couple of killdeer. The female (below) was freakishly friendly towards me, so I knew it's one of the chicks I observed some time over the last few years. At first, I thought it was Dee, then Firecracker, then Little Miracle. Now, I think it might be Smudge. She walked right up to me.
Here is a young male, younger than the killdeer above. He is a spitting image of Killer (AKA Kip), so I think it might be one of his sons. If the killdeer above is Dee, this would probably be her son. If it's Smudge, then this might be her new mate:
Look at all these gulls and coots. Lots of ring-billed gulls here like last year and the year before.. Hopefully, they will move on before the ducklings begin to hatch.
