Chinese Bulbul 白頭鵯 (hainanus?)

Chinese Bulbul sometimes shows dark tips to the white nape patch, as on this bird. It seems to be especially prevalent in autumn (perhaps because the birds are in fresh plumage - the dark tips wear off during the winter). You can see that the base of the feathers in this area show the typical white pattern on this bird. I seem to remember a discussion about a similar bird at Ng Tung Chai a year or two ago.

I saw the hainanus subspecies for the first time this year (in Guangxi) and was surprised at how distintive it actually is. The back of the head is fully black, with no trace of white. See the following links: ... _ID=&pagesize=1 ... _ID=&pagesize=1
