Seen in Yung Shue Long Valley, Lamma Island this morning. Shame about the perch :cry:

No takers..... googled it & found a very similar image from I-Owen, HK... so am going with immature Plaintive Cuckoo

There is an image by Allen To on the HKU site with a back pattern almost identical to yours:

But the bill on your bird looks unusally large and chunky.   I'd be interested to hear from someone with experience of this bird in the field.

I would say this is a plaintive cuckoo - the overall coloration and upperpart patterning (especially the pattern of the tail) is typical for that species. Size is difficult to judge, but I would say it seems like a small bird (as plaintive).

The bill does look a little bit heavier than normal but is probably within the range for plaintive.
