No luck re-finding the Cuckoo this morning. Myself and a couple other birders looked until about noon. The park has a large and very densely wooded area that is great habitat for a passing cuckoo so it could be around somewhere still. According to Neal, who I contacted yesterday, it was seen on the south edge of the old road that goes into the river on the west side of the park. It's quite birdy, sunny and warm here so it was a great place to bird today.
