Today I heard it first from inside the house. I went out side and saw the yellow billed cuckoo high in a cherry tree. After looking at it through binoculars, I saw the yellow underside of the bill and knew what it was. I have been listening to the bird calls on e-nature.com of the black and yellow billed cuckoo and this was definitely the yellow billed. Last week I saw and heard the black billed up the street from me and there is definitely a distinct difference between the two. Fred Rutland
