Observation just at the border of Lerderderg State Park. Comment by Peter Marriott: the head pattern, the dotted line is sort of interrupted, the black mark suggests P. diemeni. Head close-up in second image. Pantydia genus is profiled in Moths of Victoria Part 8.
A large number of these Noisy Friarbirds are feeding in the Yellow-gum blossoms at the moment much to the annoyance of the resident Red Wattlebirds and Noisy Minors. They are constantly calling/chattering so are easy to locate.
