Went looking for the Black-billed Cuckoo at Blue Mash late yesterday afternoon and this morning between 8:30 and 9:30 AM, no luck.  The birder's log in the box at the parking lot indicates that the bird was seen in the morning (more toward the early side) in the vicinity of the parking lot or nest box B which is near the parking lot on the mornings of 4/27, 4/28, 4/30, 5/1, 5/3 and 5/4.
