it's a yellow-browed warbler - best guess in this condition.

Gary, thanks for your comments. A major factor I considered this being a Greenish Warbler instead of a Yellow-browed Warbler was its dark-coloured legs. I would therefore appreciate it if anyone could comment on this.

Yellow-browed type and Greenish type is obviously different in size. You can note the difference if you are familiar with them. The wing bar for both are also looks quite different. YOu may note this one (wing bar) is rather solid and with dark band in between compares to Greenish's wing bar is rather weak.
Under bill color is also very different.
Given the shifted color tone, you cannot justify the greenish color on its back but you still can see its yellow brow.
ID of such subtle species need checking a combination of features not just one .

Gary, many thanks for your clear elaboration of the differences between these two birds.
