Mixed flock with both CACH and BCCH. This one is definitely a Carolina.
Another (possibly) valid cocoon, found within 5 ft of the first one.
Seventh cocoon. Almost certainly still has living pupa inside.
The eighth, and another valid cocoon. Unfortunately the twig broke while I took this picture, so I will be taking this particular cocoon home to release it in the summer.
Tenth cocoon. Found right beside number nine. Another likely valid one!
