トケン, Cuckoo

I spent a few hours watching this bird, thinking it might be an Oriental Cuckoo that had stopped by this autumn. If only it would call out! Regarding the banding on the chest and the vent it is most likely a Common Cuckoo. All images (taken with 300mm f2.8 and tc 1.4) have been cropped considerably.
