Same bird seen yesterday. Crown and powder blue, paler than I would expect for flava flava, ear coverts perhaps greenish but colour not easy to tell at range. Supercilium narrow, appearing white, but not easy to see because the bird was distant, so cannot be certain it was all white. However, it was wider behind the eye, and this part was white, and ended before rear of ear coverts. Underparts bright yellow, including throat, perhaps white submoustachial, but not clear from the views obtained. Upperparts green, with white wing-bars and tertial edges. tail black with white sides. Seen next to make and female flavissima, when powder blue cap was obviously different from green of flavissima. Not as bright as the brighter male flavissimas, but brighter and more extensively yellow below and green above than the females.
