The thick-headed fly is an amazing wasp mimic. Dark red with black marking and a yellow face. the species has a variable appearance. One set of wings and fly-like antennae help differentiate it from wasp in appearance.
A "crackle" of cockatoos*. No doubt that's the sound they make when they're eating your house!... but crackle it is, and that's the correct collective noun for a group of cockatoos! If ever there's a book written about birds behaving badly in Australia, then cockies will be on the front cover, guaranteed! But they are gorgeous and funny and fascinating, and I love them. Iconic and quintessentially Australian birds! Here's a spotting I made at the same time, of a bird nesting in the bush a short distance away.... https://www.projectnoah.org/spottings/17... NB: The first three photos in this set were taken in March, 2021, and the later three were taken last week, in June 2021. The grooming pair form part of a subgroup of about six birds, and they frequent the area often, sometimes going from house-to-house looking for handouts. The larger group forms a substantial part of the crackle, but there are still many birds that weren't present here. I could hear them off in the trees farther afield! PS: There's loads of information about the species available via the reference links.
