It is still poor, but better than few weeks ago !
The Crested Goshawk has gone (confirmation by a coffee shop owner who has followed its "exploits"; particularly, he saw it catching a rat), and the female Fujian Niltava also.
This male Chinese Blackbird is significantly larger-looking and more powerful than our Common Blackbird of Europe. I also read somewhere that this species shows typically yellow "knees" and a bare yellow patch in front of and also behind the eyes. And look at its bill, clearly broader than the one of Merula.
In good light, this bird shows obvious bluish sheen on the coverts. In fact, only the flanks, belly and breast are really black.
In mid-winter/spring, when the plumage is worn, Yellow-browed Warblers lose some of their brightness and become greyer. The grey head contrasts with the green-olive coverts/wings as shown in the photo below.
Olive-backed Pipit. Individuals I encounter in this park are much tamer than elsewhere.
