These photos were taken 2/2/2014 in Fukuoka Japan by me. The bird stayed around for a short time. It made no calls and soon flew away. I thought it may be a bush warbler, as they are quite common here, but couldn't discern any eyebrow markings. There is a blue tinge to the tail as well as some orange tinge on the sides, and a white throat patch, so thought it could be a female siberian bluechat, (red-flanked bluetail). Habitat a mix of bamboo and bushes. Thanks for your time, Kawasemi.
