This flighty little fellow is a Tawny-crowned Honeyeater, a mid sized honeyeater of Australia's heathlands. It's a real flibbertigibbet, and despite knowing almost exactly where these guys were and stalking them for two days, this is the best shot I could get. It's good enough for a record shot, I guess.
