I went down to Washington Square Park hoping to see an eyass head or two pop up out of the nest, but it wasn't to be. They're still very young, and I didn't catch a feeding. (At the beginning of a feeding, a well rested young eyass might just reach high enough to see.)
Instead, I got to see Bobby bring a nice long strip of paper to the nest. It looked like it might have been wallboard tape. At one point, the female ends up with it on her head like it's a hat and another time it looks like a Möbius strip.
