    Please help ID the wagtail, Jiangsu Province, China

    I would agree with the original ID on both counts. The second is a pretty typical adult female Citrine Wagtail. In addition to the features already pointed out, the pale forecrown eliminates EYW. Taivava, as you probably know is a very different bird with typically solid ear coverts

    Blue-and-white or Zappey's Flycatcher? - Beijing, China

    Hi Andy, I don’t think that is fair to say. I think all males are identifiable if seen well. And no one has really tried very hard separating females.

    Blue-and-white or Zappey's Flycatcher? - Beijing, China

    I missed the link to other photos of the bird in the original post. given how dark the throat and breast it, I am confident this a first-year male intermedia.

    Blue-and-white or Zappey's Flycatcher? - Beijing, China

    An interesting post, and one I can perhaps shed some light on. I am aware of further research into the taxonomy of Zappey’s and Blue and White Flycatcher, which supports the conclusions we came to in our 2012 paper, but this does not seem to have been published. A fair amount has been learnt...

    Pin-tailed or Swinhoe's Snipe? (with tail pictures) Singapore

    With that tail structure (3-4 narrow outer tail feathers which are clearly of differing widths) this is a Swinhoe's Snipe. Pintail has 6-7 very narrow (c 1 mm in width) tail feathers which are all of a similar width.

    Butterflies of the Forbidden Kingdom - China

    I was there as part of a birdwatching group in May and it was utterly horrendous. On the worst day I had my passport checked 7 times. The final time I was dragged off the street into the nearest police station having just checked into the only hotel in town that allows foreigners to stay...
