I wondered about that because the Osprey was shrieking real high-pitched, right. But when it got back to the nest I could hear a lower-toned bird. So I wondered if there was something in there or maybe it was just another bird nearby I couldn't see. Also, I didn't notice until I was back in traffic but there's another nest with a somewhat smaller bird on the other side of the street. I took this while I was waiting for the light to change.
And then as I was driving up SR 54 a few miles away I saw another nest (also think it was Osprey) on top of a billboard. I thought it was part of the billboard at first, like how sometimes the Chick-Fil-A cows will sit on top but it was a nest! Good to see the birds getting busy making the next generation.
