Beautifully made little nest hanging in the outer branches of a small Bundy eucalypt about 6 ft off the ground. Made from mainly spider webs woven together. Most likely either a buff-rumped or a Yellow Thornbill as both have been observed in the area.
Some noisy minors harassing a nest hollow about 60cm off the ground attracted my attention. On inspection a small speckled grey 'hawk-like' bird (approx 20cm) flew out and was chased by a minor who plucked a few feathers most likely from it's tail (see other photo). It all happened too fast for a photo! 3 eggs in the nest which was lined with leaves and some grass.
This Megachile bee is pictured both leaving and entering her nest in an old fence post which has had a number of holes drilled into it. She has been identified as Megachile Hackeriapis canifrons by Bernhard Jacobi.
This Leaf cutter bee kicked dirt out of this pot plant of cacti (see photo 3). Photo 2 shows her flying towards her nest in the pot carrying a piece of raspberry leaf. Photo 1 shows her entering her nest with the piece of leaf.
This thin mud structure had been built between a box and the wall. Many of the cells are stocked with spiders. In two of the cells, a single wasp can be seen. No movement was observed while I took the photos, before we replaced the box.
