After spending a few hours with the dedicated raptor watchers above the restaurant I wandered over to Colborne Lodge. On the way back, a Yellow-billed Cuckoo landed on the edge of the picnic shelter roof opposite the guard rails that are used as winter bird feeders. It posed for 30 seconds or so, allowing a great look, before flying into a nearby tree. It's back was to me but the yellow/black bill and the rufous wing patches were unmistakable.
