One of the things I've learned since owning this expanse of woodland is to look closely at all kinds of things, whether they be on the ground, in the air, on a tree... whatever. Of course, not being a scientist, I tend to see things that I can only guess at. The bug above would not be an insect since I was taught at school that they have six legs! Is it some kind of millipede?
And these were sitting on the gravel next to the car, getting very cosy with each other. I've seen the stripy caterpillars (larvae) in Melbourne that people say spit at you, but these were about 1.5 cm long and hanging around in this small group.
Any guidance as to what either of these are would be appreciated!
On the other hand, after watching some birds out the front of the house and making close observations through binoculars, I was able to later find my bird book and identify them as white-winged choughs. And I was right - they did behave just like my chooks did in the back yard as they scratched and dug and pecked.
Their curved beaks and red eyes make them easily identified as not crows! Now all I need to do is keep an eye out for their mud nests.
