Over past weeks our local Yellow Gums have started to flower … but not the heavy blossoming that I was hoping for.
Rotunda Park is notable for its magnificent veteran Yellow Gums and in the past these have lured Swift Parrots to feed on the nectar during April as they arrived back on the mainland from their Tasmanian breeding grounds. In years of bountiful flowering the birds remained right throughout winter.
I fear that once again this year the paucity of flowering won’t be sufficient to encourage the parrots to pay anything more than a fleeting visit. With the Easter break promising excellent weather I’m hoping a few ‘swifties’ might be about.

As summer has drawn towards its end, the number of invertebrates in our bush at Strangways has been dwindling. But there are still some willing sitters for the macrophotographer’s lens. After reaching considerable numbers early in February, there are now only a few Eucalypt Tip-wilter Bugs Amorbus sp. around, including this nymph, which was not far from adult size. The bush has many webs of Jewel Spiders Austracantha minax and some of these might not be happy about it, but have offered a pretty detailed view of their spinnerets, palps and fangs. The gaudy caterpillar of a Tussock Moth Acyphas sp. does not give hints of the more subdued presentation of the adult moth to come. The tussocks of hair from which it takes its name are clear though, as are the two glands at the back that exude a secretion to protect from ants.
Reliable to find at this time are the Muscle Man Tree Ants Podomyrma adelaidae, so named as they live in trees and have well-developed leg muscles for all the vertical work they do. This crew lives in a branch of Long-leafed Box and there always seem a couple on guard duty at the entrance of the nest. To me they are sweet-looking ants and the creamy dots on either side of their abdomens complement their brown skins beautifully.

After a very busy week there is nothing better than a quick spin around the margins of Lake Cairn Curran. It’s not just the waterbirds that I’m after – small woodland remnants and the plains country invariably produce a nice assortment of birds. I even caught a distant view of a White-bellied Sea-eagle.

This nest, belonging to a pair of Scarlet Robins has featured during construction in an earlier post.
I’ve made a couple of brief visits over recent days and been delighted by the progress – the female is now sitting on three eggs, a typical clutch size. The nest site is somewhat unusual from my experience. Not so much the site, secreted in a sapling Long-leaved Box, but more so the height. Most nest I find of this species are usually at least 5 metres above the ground.

This nest was discovered earlier in the week at the Rise and Shine – it belongs to a Yellow-tufted Honeyeater. As you’ll see in a moment, this species typically nests low down in a shrub or eucalypt, but on this occasion selected a crevice on the trunk of a mature Yellow Box.

Another visit the following day provided a surprising turn of events – a pair of Yellow-tufted Honeyeaters were visiting the nest, removing small pieces of wool and bark to add to a different, partially constructed nest in a small Long-leaved Box nearby. It’s a puzzle … was it the same pair having second thoughts and choosing another location? Or could it have been a different pair pilfering material from the original nest builders? I’ll never know!

Postscript: John Hutchinson’s terrific Avithera blog has an article on his observation of Brown-headed Honeyeaters apparently dismantling a White-naped Honeyeater nest in Gippsland. John’s note also makes mention of an article (see below) in the journal Corella which I’ll track down soon.
LEY, A.J., D.L. OLIVER & M.B. WILLIAMS. (1997). Theft of nesting material involving Honeyeaters (Meliphagidae). Corella21: 119–123.
Thieving of nesting material in 10 honeyeater species and six other passerines is described, in the Bundarra-Barraba region west of Armidale, New South Wales during a study of Regent Honeyeater’s biology in 1995-96. Theft of nesting material was from both active and inactive nests. The contribution of theft to nest parasite transfer (e.g. lice) and to nest failure in Meliphagidae is discussed.

This Saturday, 24 September, the new Friends of the Box-Ironbark Forests publication, Eucalypts of the Mount Alexander Region, will be launched at 10.30am in the Castlemaine Library foyer.
This 90 page guide by Bernard Slattery, Ern Perkins and Bronwyn Silver aims to help the beginner train the eye to see the differences between eucalypts – and to appreciate how spectacular they sometimes are. It presents the commonest species of the Mount Alexander Region, generously illustrated, and clearly described in plain language. Though firmly based on one local area (the forests and reserves around the town of Castlemaine), it describes species common to the whole Box-Ironbark region, and would be useful to any enthusiast in that region, from Ararat to Chiltern.
The publication of this book has been made possible by a generous grant from the Worrowing Fund through the Norman Wettenhall Foundation. Other supporters have been the Castlemaine Field Naturalists’ Club and Connecting Country.
The book’s cost is $10 and people buying it at the launch will receive a selection of free tree-related bookmarks and a FOBIF fungi poster. Proceedings will start at 10.30 in the Castlemaine library foyer. Refreshments will be served.
I’ve had a sneak preview of the book – it’s a fabulous publication and a significant contribution to further developing our sense of place and appreciation of nature in central Victoria. I feel extremely honoured to have been asked to launch the guide.
