Phylloscopus from Tainan, Taiwan, April 2020 (1 Viewer)

I received the attached JPEG from Roy Slaterus this morning (who has kindly given permission for me to post it here). Roy is the author of the article on The Sound Approach website linked to in #6. I think this makes him perhaps the best person to look at this bird, and he has been kind enough to do so over the last couple of days.

The unusual calls I highlighted at 1.5, 2.5, and 8.0 seconds in #16 are treated as calls, just atypical ones. Calls at such high frequencies are given by Two-barred Warbler, hence these vocalisations fall within the range of that species.

I've had some very productive exchanges about this bird (both with Roy and here on BirdForum). It seems to be one that is to some extent at extremes (both in terms of its outward morphology and its vocalisations), but ultimately one that is 'just a Two-barred'!

Thanks for an interesting discussion on this bird. Very useful.

Yes, thanks John. Although this bird didn't quite live up to the promise I at one point thought it might have, discussion of it has nevertheless been educational and rewarding.
