Platypus update from Gold Creek!

by

Cold mornings and the pandemic haven’t stopped MCCG member Ed Frazer from getting out to monitor platypus populations in Gold Creek!

Ed has been monitoring the platypus in two big pools on his property for the past twelve months.

You may recall his articles from late last year about a family with two babies.

Ed has continued to observe the youngsters and you’ll be pleased to know the wounds on the one which was attacked have now repaired.

At one point Ed was so concerned he consulted with Dr Chris Hosking. Her advice was to monitor the platypus closely and fortunately this has paid off.

But: are the youngsters still there?

To find out more and for a marvellous read about Ed’s platypus families, please head to our latest Bush Bites feature:  Platypus watch August 2020

Our sincere thanks to Ed for his ongoing contributions to the website, and to the MCCG in general.

Don’t forget to sign up to join Dr Hosking’s Platypus Survey on Sunday 13 September.

Platypus watch August 2020 – Ed Frazer

by

In November 2019, Ed Frazer introduced us to a young Platypus family who also call his property home. As breeding season commences in August 2020, Ed updates us on his playful residents:

It has been 12 months since I started monitoring the platypus in the two big pools in Gold Creek, which borders my property in Adavale St.

I have regularly observed and photographed the two youngsters that were bred in the 2019 season. They emerged from the den in November 2019. One was attacked and wounded and it has now repaired its wounds.

I haven’t seen or its sibling since July 3, and my overall sightings have greatly reduced since the end of June. Before then I regularly saw platypus every day.

Lately their behaviour has been different, with the platypus travelling large distances between each dive. Their usual feeding pattern is a series of short dives about 45 seconds apart or feeding half out of the water where the leaves build up along the edge of the creek without any rapid change of position.

I assume the change of behaviour is due to the start of the breeding season.

Some of the large platypus I have observed have possibly been males travelling the creek to find mates.

I am pretty sure the youngsters from last year have been driven off, probably by their mother who is preparing for the next family. She would not be inclined to tolerate the youngsters as from now to November as she will need all the food she can get to produce the huge quantities of milk she will need for the next batch of growing babies.

I think last year’s youngsters will have moved to find un-populated territories of their own.  I did see what could have been one a few days ago in the pools near the junction of Gold and Moggill Creeks. I would not be surprised if they work their way to repopulate the upper reaches of Moggill Creek.

Our last MCCG Platypus Survey showed that there were no platypus in this part of Moggill Creek because the water level had been depleted by drought and excessive pumping. Hopefully this year will see a return of the platypus to the area.

The female that raised the two last season has used the same birthing den for many years. It is directly below one of my hides so I can keep a good track of her. Even if I don’t actually see her, I can often detect her movements from the bubble trail she often leaves on the surface.

I did not detect her between July 5 and July 20. I think she will have laid her eggs and is now curled up in the den hatching them. Even after they hatch she will only leave the den for a short time to feed and that will probably be in the middle of the night so I doubt I will see her over the next month.

The platypus mother, November 2019

By September the young will have grown enough that she will have to go out feeding regularly and I’m sure when we have the 2020 Platypus Survey in early September she will be observed as she has been nearly every year. Last October she was out late in the mornings and once I saw her at 2pm on an overcast day.

Hopefully I will see the young again as they emerge from the den in November. It’s quite likely they will add to the population of platypus we are monitoring with our Annual Survey of the Moggill Creek Catchment.

The tale of two non-native grasses. Talk by Prof. Jennifer Firn

by

On the evening of Thursday 30th July, MCCG held its first Public Meeting of 2020 in Brookfield Hall. Prof. Jennifer Firn from QUT gave us a very interesting talk on the subject ‘The tale of two non-native grasses’. Prof. Firn, who is an environmental ecologist, proved to be a very enthusiastic and engaging speaker. She told us that there are approximately 2200 non-native (exotic) grasses that have been introduced to Australia since white settlement, far outnumbering the native species. Some of them have agricultural benefits, but many have spread into conservation areas where they have a negative impact on biodiversity and traditional aboriginal methods of land management. The talk was greeted enthusiastically by the audience, which was limited by the need to comply with covid-19 restrictions.

Councillor Greg Adermann supports MCCG

by

Councillor Greg Adermann, the new Councilor for Pullenvale Ward, attended a meeting of the MCCG Management Committee held on Thursday 23rd July at our headquarters, ‘The Cottage’ at Gold Creek Dam. We presented him with a copy of the book that was produced in 2017 for the 20th Anniversary of MCCG and to tell him about some of our current plans. Cr Adermann expressed very strong support for all of our work and we hope to work with him on some future projects to enhance the local environment and engage more of the local community in our activities.

Reducing our use of rodenticides

by

Australian birds of prey such as owls and raptors can be killed by internal bleeding when they eat rodents who have ingested rat bait.

In 2018 a Western Australian study found that 73% of southern boobook owls which were found dead had anticoagulant rodenticides in their systems.

Small mammals such as possums, antechinus and bandicoots can also fall victim to bait that has been laid out to attract and kill rats and mice, and even larger mammals like wallabies and kangaroos have been known to suffer from rodenticide poisoning.

The Australian Pesticides and Veterinary Medicines Authority (APVMA) is currently asking Australians for their views about the regulation of rodent poisons.

On their website, Birdlife Australia offers advice about minimising our use of rodenticides. They also invite you to take a pledge to leave Second Generation rodent poisons on the shelf.

For more information, please visit their website.

The MCCG Native Plant Nursery at Gold Creek Dam recently installed a Bard Owl nesting box in the hope of attracting a pair of barn owls to take up residence and help control rodents in an environmentally friendly way. Rats and mice continually cause damage to seedlings in the nursery. The nesting box was funded by part of a grant from Brisbane City Council that supports the operations of the nursery. Thanks to Andrew Wilson and Damien Egan for installing the box. We will keep you posted if any barn owls (or other native wildlife) take up residence!

Brisbane City Council Free Native Plants Program

by

MCCG members have an advantage when it comes to planting out their properties. We provide free plants for our members, mostly grown at our Nursery from seed collected by volunteers, all year round.

Residents who have purchased a newly built home or moved into their owner-built home within the past 12 months in targeted suburbs in the West can claim four free plants.

For more information, head to the Brisbane City Council website.

If you’re a MCCG member, don’t forget our Nursery is stocked with a wide range of trees, shrubs and understorey plants all looking for a good home, and free to members.

A list of available plants is available here: Grasses and other Herbaceous Plants

Do birds of a feather really flock together?

by

In fact, birds of different species engage in mutual “mobbing” behaviour, usually to ward off predators.

In his latest issue of Feather Fascination,  Jim Butler describes calls exchanged in collaboration between Noisy Miners and Magpies. Remarkably, there is clearly a common code of communication between them.

And it appears that this innate understanding is global.

To find out more, head to Jim Butler’s Feather Fascination July 2020.
