Tangentially gardening-related is birds and nesting. We put up two boxes to attract rosellas, but one was instantly colonised by the noisy miner, a native so aggressive and invasive that you can get a licence to trap and humanely kill them on farms. We keep removing the nest material to discourage them, and though it goes against the grain, eggs too.
A better thing is the discovery of a blackbird's nest on the top shelf of our shed, accessed by the birds through the open eaves. They've nested right on top of pair of secateurs I'd wanted to take in for sharpening, so they'll have to wait. Today I went in to get some lawn clippings for the compost heap, and there was the female on her nest, eyeing me, but unmoving, though I later saw one blue egg. While blackbirds are not native, neither are they a pest.
The rest of the garden is spring tidy-up, some it with an eye to our first house guests since we moved here; most of it cleaning windows so they SEE the garden. Lots of rain though, which is good, as we should have mulched 2-3 weeks ago. In fact it's thundering now. 
Melbourne Cup today: a public holiday for a 3-minute race, and you know what? I still can't find a form sheet which tells me which horses are grey, and which wear sheepskin nosebands; the only horses I ever lay a bet on.
