I quick walk around this morning with the little guy with only the usual sparrows, magpie-robins, ground pipits, fantails and tailor-birds. I saw the guys in the images below, as I was walking out, which saved my morning.
The blurry images of the first bird showed purple on the side neck (which I did not notice in the field (no bins), so a female Fujian Niltava. I did not make out any neck colouring at all on the bird in the second image. It took me about 8 more hours to realize that it is (I think) the same species - I think we may have two female Fujian Niltava in the HBG.
