Photos of two different flies in different parts of the park in different years, but appear to be the same species. It seems to like fungus - the primary photo is on an unnamed brown bolete which is very common in the park. The other two are on a Rhizopogon species probably associated with pine trees.
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.
