OUTING REPORT: Ambrose Treacy College and Sherwood Arboretum, 03 November 2019

At 7.30am sharp, nineteen Field Nats, including our driver Phil Haxen, departed by bus from the Neil Street car park bound for Ambrose Treacy College, Indooroopilly. On arrival we met up with Lesley Beaton and John Ball, who had travelled independently. The focus of our visit was Brother’s Gully. 

An article by Alexander Davies entitled Brother’s Gully: A story of habitat regeneration increasing biodiver-sity, in the June 2019 edition of “Metamorphosis” the Magazine of the Butterfly and Other Invertebrates Club (BOIC) had alerted Ben Gundry to the potential of the Gully for a visit. To quote from the article: “Brothers Gully is a patch of sub-tropical riparian rainforest adjoining mangroves, located at the south western end of Ambrose Treacy College, Twigg Street, Indooroopilly, Brisbane. The Gully area starts at the top of Kate Street, Indooroopilly, and stretches 140 metres till it reaches the riverbank”.

The Gully is the subject of a weeding and revegetation program, initiated in 2015 by a Year 11 student, Alex-ander Davies, with support from the school and his grandparents, Trevor and Tina Lambkin. Alexander, our guide for the morning, had been motivated by the sight of this small remnant area of riparian rainforest becoming choked by exotic weeds. He told us that revegetation of the steep Gully is also supported by the Brisbane City Council under its Land for Wildlife program, and free plants from the Moggill Creek Catchment Group (MCCG) and Save our Waterways Now (SOWN) nurseries. But the weeding and planting is all done by students (Gully Men) under the direction of Alexander.

We were impressed by Alexander’s knowledge of both the flora and fauna as he guided us around different sections of the Gully, some relatively advanced and others still being cleared in readiness for planting. Over 180 (mainly local native) species of ground cover, understorey, mid-storey, and canopy plants have been grown to enhance the existing vegetation. An increasing number of birds, mammals, reptiles, and invertebrates have been recorded since commencement of the project – a reflection of the plant species selected.

After a leisurely lunch on a wide deck overlooking the river, we departed for the Sherwood Arboretum, to be joined by Tricia Allen and her grandson. On arrival we were met by Brisbane City Council volunteer Guides, Dick and Jankees. Opened on 21 March 1925, the heritage-listed Sherwood Arboretum covers an area of 15 hectares, contains approximately 1,100 trees from about 300 species, and comprises parkland, artificial fresh-water wetland and has an extensive frontage to the Brisbane River. Of particular note is an avenue of Queens-land Kauri Pines (Agathis robusta) planted for the 1925 opening. 

Splitting into two groups, we followed our knowledgeable guides as they identified fine specimens of native trees, some local and others from further west that were familiar to many of us. A boardwalk along the Bris-bane River introduced us to three species of Mangrove. A very comprehensive description of the Arboretum is available on Wikipedia and interested readers are encouraged to access it for further information.

Leaving at 4.00pm Phil drove us safely back to Toowoomba, where we arrived at 5.30pm after an enjoyable day blessed with perfect weather

SPEAKER’S REPORT: Dr. Henrik Ferreira

Dr. Ferreira’s presentation could well be named ‘Birds from Around the World’ as his 341(!) seven second each photos of birdlife began in Brazil and finished in Australia. Each segment was punctuated with stories of inter-esting and humorous situations he found himself in during his bird photography trips. As well as birds many other animals, insects and flora were incorporated into his address including jaguar, caiman, snake, deer, water buffalo, capybara, river otter, fox, giant snails, bees, lizards, fish (piranha!) and frogs.

His Brazilian trip in 2013 encompassed three distinct regions: The Pantanal, a huge tropical flood plain and wetland in the western state of Mato Grosso; the Ubatuba, a coastal forested area on the Atlantic north of Sao Paulo; and the Itatiaia National Park, in south-eastern Brazil’s Mantiqueira Mountains. The following are just some of the bird types that were shown: guan, trogan, ant shrike, woodpecker, toucan, heron, ibis, humming-birds, tanager, eagle, and finch. Some of his photos have been prize-winning, capturing birds in typical, or odd and funny poses, in flight, in pairs, and in flocks.

The countries Dr. Ferreira covered next were Hawaii, England, New Zealand, and South Africa, finishing in local and far western and northern regions of Queensland. In each, he showed us birds that were the most uni-que or beautiful of that country.

This was an impressive, breathtaking at times, whirlwind presentation backed up by digital photo books of each of his trips for us to browse through afterward. This was roughly only 20% of his total collection, so I’m sure we can look forward to inviting him back to show us more in the future.

BIRD LIST FOR CLUB OUTING, 08 SEPTEMBER 2019

Highfields Falls: On a windy, but clear, morning, we parked on the “James Byrne” side of the Reserve and were pleased to walk into the forest to beat the wind. Once at the Falls side, we were totally out of the winds. Most of our sightings occurred on this Falls side, where, of course, the birds had access to the trickling stream.

Our bird list for the Highfields Falls Reserve morning: Lorikeet (most likely Scaly-breasted); Red-browed Finch; Grey Fantail; White-naped Honeyeater; Rufous Fantail; Grey Shrike thrush; Eastern Yellow Robin; White-browed Scrubwren; Lewin’s Honeyeater; Variegated Fairy-wren; Golden Whistler; Leaden Flycatcher; Crested Shrike-tit; Galah; Eastern Whipbird; Straw-necked Ibis (flying overhead at the carpark).

Williams Park (middle of the day) list:

(at the Park) Scaly-breasted Lorikeet; Noisy Miner; Crow; Currawong; Magpie; Galah; Tawny Frogmouth; and Jim Ball’s late-arriving King Parrot. (on the creek-side walk) Grey and Rufous Fantails; Common Bronzewing pigeon; Brown Cuckoo-dove (Mike Ford’s sighting); Superb Fairy-wren; Sulphur-crested Cockatoo; heard a whistler (probably golden).

The bird of the day, and it was my sighting, was the Crested Shrike-tit (Falcunculus frontatus). I have only ever seen it a few times, and never here, although Jean photographed it here two years ago, in the creek, a little further above the Falls. There are three races, with our “frontatus” being the most widespread. I was watching the Leaden Flycatcher on a branch over the path when it was “buzzed” by the shrike-tit, which then gave me 15 seconds of excellent viewing. It is a beautiful bird, with strong yellow body markings below, olive on the back and vent, and otherwise grey. The black head and throat patch are most distinctive, with two white stripes across the face, separated by a narrower black stripe through the eye. The crest is, I think, always partly or fully erect – giving it an over-sized “boof-headed” or Mohawk appearance. “Simpson and Day” tells me that “they feed mostly in the upper branches, prising invertebrates from the bark with their robust bills. They give distinctive chuckling calls or drawn-out plaintive whistles.”

I was thrilled with (and Jan Veacock was jealous of) my sighting. Enough said.

OUTING REPORTS - Helidon Hills, 06 October

In a good year, this would have been a truly wonderful outing. We had a very knowledgeable guide in Martin Bennet. He took us to two different sites, not far apart but on different soils, each with its different suite of flowering plants. Both were species-rich sites but alas, the season is so dry that there were no flowers to be seen at all. A future outing to the same sites in a good spring would be very rewarding.

We did enjoy seeing the “Koala fern” (Caustis blakei) in its native habitat and discussed the fact that it is no longer being wild-collected for floristry. Research at the Gatton Branch of the University of Queensland has found the secret of propagating this difficult plant, so it is now being grown for the industry. We also marvelled at the “un-grevillea-like” leaves of Grevillea singuliflora, and looked for adult trees of the woody pear (Xylo-melum pyriforme ). There were many young plants, with their very distinctive leaves, but no mature ones to be found.

Those of us who love plants whether they were flowering or not had a great morning. Others probably wouldn’t include this one in any list of the club year’s highlights, especially as the birding was also very poor.

As usual, though, we managed to enjoy ourselves. Outings are always a good chance to spend a happy morning with friends, and it was good to catch up with Martin as well. We also had the pleasure of the company of several people from Lockyer Uplands Catchments Inc (LUCI). Thank you, Bob and Sandy, for your parts in organising it for us.

Thirteen members plus two guests gathered at Helidon for an excursion approximately ten kilometres along the Seventeen Mile Road. We visited two areas of diverse vegetation and soil types (see detailed lists). Despite the heat we enjoyed the walks and morning tea at the roadside. The effect of dry weather was evident and there appeared to be limited bird movements. Enthusiastic discussion on vegetation and soils resulted in a very interesting learning experience. We had lunch at Helidon Park, with a brief overview of the formation and uniqueness of Helidon freestone, including its commercial use, particularly in the public buildings in Brisbane. Quantities of this stone are exported, mainly to China.  There was also a brief history of the various sandstone quarries that were located along the Seventeen Mile Road and Air Force Road.

The Helidon Hills is not renowned for its birdlife, presumably because of the lack of water on dry stony ridges. However, on this occasion the birds were missing, hopefully in action elsewhere in the district. Alice Creek is not far away as the bird flies. There were birds at our lunch spot in Helidon township. These included brown honeyeaters which were very vocal. Our thanks to Jan Veacock, Bob Fuller and Martin Bennett for their efforts in planning this excursion.

Bird Report for Helidon Hills outing

Past Helidon Hills excursions have primarily exhibited a “botanical bent” in their naturalist purposes and Jan Veacock has said that a list of seven bird sightings has historically been a good result – with Yellow-faced Honeyeaters often predominating. Most of these past excursions would have been in good, or at least “aver-age”, seasons.

Today, on our two stops on tracks leading from Seventeen Mile Road, a little north of the Goldmine Road turn-off, we struggled to compile a “heard” list. This is an index of our utterly dry winter/spring circumstance, our walking along ridge-top tracks (therefore no surface water – and probably none in the creek lines well below either!) and our walking in the heat of the day. The vegetation was stressed, with only the grasstrees consist-ently looking freshly green.

We heard the Grey Shrike-thrush, intermittently, and at some distance; the White-throated Tree-creeper, occasionally; the Striated Pardalote; and few other anonymous, muted churrings. [NOTE: no Yellow-faced Honeyeaters at all.] I “saw” only one LBB (little brown bird), 20 metres away in the canopy, as it promptly doubled its distance from me. A thornbill was my guess.

At morning-tea, first Shirley Cormack with hot coffee, then John Ball with wetted dried fruits, were tantalising many native bees that were quickly attracted to any available moisture.

Report on October Speaker on Madagascar

Acknowledgement to photographer Yann Bertrand

Andreas Helwig, Senior Lecturer in Electro-Mechanical Engineering at the University of Southern Queensland gave a wide-ranging and fascinating talk on Madagascar. He began by giving some background information about the country: it is about a third of the size of Queensland, but its population is about 27 million; it lies off the east coast of Africa, but its formation is part of the Gondwana story, the supercontinent that was formed about 550 million years ago (mya). About 135 mya it split from Africa (as part of India). Then about 88 mya it split from India, as India made its way northward. It was thought to be peopled initially by Nazimba or Kimosy people (like Negrita pygmy people found in Andaman Islands). Migrations of Malayo-Polynesian peoples took place from 400 to 700 AD, followed by Arabs, Bantu tribes (in 1300s AD) and then the European arrival from 1580 onwards. As expected, these migrations have over time created a great amount of diversity in the Madagascar population.

It is currently a very poor country with most inhabitants falling into the class of ‘poor’ with wealth concentrated in the hands of a minority. Poverty and poor agricultural practices have led to a lot of slash and burn type of agriculture, to the detriment of the forests on the island. Many of the hills have been denuded and aerial photographs show that there is greenery only in the valleys between hills. Madagascar has very old geology, and has many minerals, which has attracted mining but does not seem to have diminished the levels of poverty. The landscape is very volcanic.

Biodiversity, which is under threat by development and poor policies, has provided the country with many plants with medicinal properties. Helwig gave as an example the story of the use of liana sap to heal a child that had got very badly burned on the stomach area. Currently, over 400 ‘medicinal plants’ are being investigated for their medicinal value – anti-malarial, for diabetes, for leprosy, for kidney stones and so forth.

There are a number of plants that are well-known and are native to Madagascar, amongst them the Poinciana, Bismarck palm, the polka dot plant (Hypoestes phyllostachya) and the baobab (Adansonia za). A very popular wood is the Malagasy Rosewood and its felling is having an impact on the rainforests of the island. Black ebony is another tree in which there is much illegal trading.

Photo from the slide presentation: Jewelled chameleon

In terms of fauna, there are a huge variety of lemurs, from one that would fit into the palm of one’s hand to one as tall as a person when standing on its hind legs. Radiated tortoises can live up to 300 years. The jewelled chameleon of Madagascar lives up to its name. The Madagascan giant spider lives up to its name also, judging by the size of the web it is able to spin – dwarfing the man who was in the picture also. There are seven species of silkworms.

Andreas Helwig conveyed wonderfully the variety of land formation, the diversity of people, plants and wildlife, but also the poverty that afflicts the country. One might wonder what an electro-mechanical lecturer was doing in Madagascar (he has visited this country annually for over twenty years). This was revealed at the end of his talk. He has been actively involved in a school for children in Antananarivo, the capital of Madagascar. Project Madagascar, as it is called, is a Toowoomba-based not-for-profit committee of Civic Aid and Development, established in 2004. It aims to shift the Malagasy people from poverty to hope by providing affordable life-skills and education to the children of Madagascar in two Community and Learning Centres (CLCs) in Antananarivo. The following website provides further details about the school and the project: https://projectmadagascar.org.au/

Backyard Bit

Not exactly in the backyard, but just outside the front gate, I recently witnessed what I at first thought was a mating “dance” by two rainbow lorikeets. With heads bobbing, and with wings continually raised then lowered, they circled on the footpath for several minutes. When they at last flew away, I realised that they were “performing” around a dead lorikeet. The dead bird showed no sign of injury. It had possibly been hit by a car while flying low across the street, and, although fatally wounded, had been able to make its way to the footpath.

I have only once before seen a “ritual performance” by birds around a dead one of their species. This was by Indian mynas. I wonder if any other club member has witnessed similar bird behaviour.

Outing report for Sunday 08 September: Highfield Falls Bushland Park

A good group of Field Nats turned up at the Barber Road entrance to Highfields Falls Bushland Park. We were joined by three young girls aged seven, four and almost three who were delightfully well behaved.

Oh, the wind! We were hopeful of seeing quite a few birds in the vicinity of permanent water, but Jan Veacock had some historic FN bird lists which suggested with such a wind blowing the sightings would probably not be great. The first part of the walk was through open eucalypt forest with an understory of grasses and Wombat berry vines Eustrephus latifolius. The latter had orange fruits attractive to birds; the tubers are reportedly edible and certainly eaten by wombats and other native root-eating mammals.

Turning a corner in the path we descended into the creek gully, the vegetation immediately became thicker and more varied and we were protected from the wind. It was otherwise a gloriously warm and sunny day. Although there was not a great volume flowing over the falls it was a pleasure to see and hear running water and the girls were fascinated with some long-legged ants with gasters raised over mesosomas or better as described to us “the black abdomen sat very close to the head and looked almost like a black backpack”. Further along the path there were steps leading down into the gully below the falls which we also explored. The steps terminated at a steep bank, so it was not possible to go further.

Pandorea pandorana

Our group then headed for Williams Park in Highfields for a comfort stop and the obligatory refreshments! Jan read out a delightfully apt poem which I believe will be reprinted in this newsletter. Klein Creek appeared totally dry, but the circuit walk was shady and the tree ferns still thriving. There were a few interesting plants as well, some of which illustrate this article. The Wonga Wonga Vine Pandorea pandorana is a common attractive climber. The flexible wood was used for making spears for woomeras in the Central and Western deserts. One of the trees, perhaps four metres tall was totally smothered in Headache – Vine Clematis glycinoides. If the leaves are crushed the resulting aroma can be inhaled to relieve headaches and stuffy noses but the sap can be an irritant and so must be washed off straight away. The Native Cherry Exocarpos cupressiformis is a semi-parasitic shrub with reportedly edible but astringent fruit and a food for various birds and caterpillars.

It is interesting to note that the Highfields Falls creek flows eastward toward the sea and the waters from Klein Creek – when it has any – drain inland.
