[mou] ID question - YB Cuckoo

[shawn conrad]

I was at St. Croix State Park this week at St. John's Landing and heard what 
I think may have been a Yellow-billed Cuckoo.  I heard it several times 
during the morning but was not able to get a look.  It sounded similar to 
the YB Cuckoo on the Stokes CD, but didn't sound quite so "guttural" to me 
and seemed a bit slower.  Is there any bird (Common Raven???) or frog that I 
might mistake for a YB Cuckoo that would be present at St. Croix or can I 
safely assume that this is what I heard?  Thanks!

By the way, while I was there I found a pair of Scarlet Tanagers on the 
Crooked Creek Trail and another birder pointed out a Blue-headed Vireo to me 
at the dining hall near St. John's Landing.
