Trip to Bingara

On Saturday June 11 Val and I drove to Bingara to attend the Myall Creek Massacre Memorial on the Sunday June 12 with some of our family.  We travelled from Coutts Crossing to Grafton and then along the Gwydir Highway to Glen Innes, where we had a 'cuppa' stop and then on to Inverell.  From Inverell we travelled to Delungra and then turned off towards Bingara.  Before arriving at Bingara we passed the Myall Creek Massacre Memorial site.  West of Grafton we found a road-killed immature  Superb Lyrebird.  The habitat was dry open forest so it is unlikely that the bird was killed at that site.  It was most likely carried by a vehicle from the Gibraltar Range, to the west, and dropped off the vehicle at this point in unsuitable habitat.  A dead Superb Lyrebird was found some years back in the car park of Shopping World, in the middle of Grafton.  It had obviously been transported from somewhere in the ranges.

We stayed at the Riverside Caravan Park and after booking in explored the town.  I have been in the area frequently in the past 5 years deploying and retrieving cameras for the National Parks & Wildlife Service's Wildcount project but hadn't spent much time in the town.  It is an interesting town with many old and historic buildings including the Roxy Theatre.

Along one back street we found a yard full of Wallaroos, obviously a wildlife carer's home.  On the nature strip of another street were 2-3 Spotted Bowerbirds.  They were eating the flatweeds in the lawn.  I didn't check the species of weed but they looked like Catsears Hypocheirus sp.

The Myall Creek Massacre Memorial was a moving and uplifting event as it remembered a shocking massacre but has resulted in a wonderful act of reconciliation.   Check out the website ( if you want to know more about this part of Australia's history that is often swept under the carpet.

On the return trip we travelled via the Copeton Dam and had lunch near the dam wall.  Red Wattlebirds, White-plumed Honeyeaters, Superb Fairy-wrens and a White-browed Scrubwren joined us.   Leaving the Dam area we found a freshly road-killed Grey Shrike-thrush.  The orange-buff eye-brow indicated that it was an immature bird.

All in all a weekend with mixed emotions with the enjoyment of visiting such a nice piece of Australia and seeing some of the local wildlife while remembering the tragic past history of colonization.

Silver lining in clouds

This week's east coast low that battered the coast of eastern Australia with dramatic and damaging effects has also brought some benefits.  The extremely dry conditions experienced for many months across much of eastern Australia had caused the local Clarence Valley wetlands to dry up.  Wetland birds had been concentrating on the small remnants of water sitting in a few wetlands or around farm dams, which themselves were beginning to dry out.

The low brought with it hundreds of mm of rain in 24 hours causing most local wetlands to fill.  The water flowing into the Orara River flooded out over the paddocks at Coutts Crossing.  The Orara River drains areas behind Coffs Harbour so the rise in the River included local runoff and runoff from the Coffs Harbour hinterland.

On Sunday afternoon an adult female Black-necked Stork was foraging at Deadmans Swamp, Coutts Crossing, along with a number of White-necked and White-faced Herons, two Royal Spoonbills, a flock of Straw-necked Ibis and others.  At Brothersons Swamp I photographed a Yellow-billed Spoonbill that was roosting with a group of Royal Spoonbills.  On our walk on Monday we couldn't reach Brothersons Swamp as the Orara River had broken its banks.

On Monday the floodwaters had backed up from the Orara River and flooded the small bridge over McIntosh Creek.

By Wednesday the River had receded but the water remained in the wetlands.   The bridge at McIntosh Creek was again passable.

Whether this dump of water will encourage our local Black-necked Storks to breed this season will become apparent in future months.  Prior to the east coast low the chance of them breeding was virtually zero.

A fruity meal

Common Eggfly

After 30 years of developing our local native plant garden at Coutts Crossing, north coast New South Wales, the ecological benefits are very obvious.  Planting and regenerating local native plants means that the local fauna is pre-adapted to these plants and many species, in particular the insects, rely on a narrow range of native species for their life cycle to play out.  Common Grass Yellow (Butterflies) lay their eggs on the leaves of the Coffee Bush or Dwarf's Apple Breynia oblongifolia and other butterfly and moth species use other local plants species.

In recent weeks a number of these local plants have been fruiting and this has attracted the frugivorous (fruit-eating) birds to the garden.  These include the Eastern Koel, Australasian Figbird, Olive-backed Oriole, Lewin's Honeyeater, Satin Bowerbird, Brown Cuckoo-Dove, Mistletoebird and White-headed Pigeon.  The main fruiting plants have been the Bangalow Palm Archontophoenix cunninghamiana,  Cockspur Thorn Maclura cochinchinensis, Red-fruited Rice-flower Wikstroemia indica, Cheese Tree Glochidion ferdinandi and Native Grape Caryratia clematidea.

 The red fruits of the Rice-flower are toxic to humans but have no detrimental effect on birds.  There are a few old-wives tales (or maybe old-husbands tales to be politically correct) concerning the toxicity of wild fruit.  One states that if a bird eats a fruit it is not poisonous to humans - this is certainly incorrect with the Rice-flower being a good example.  Another states that all red fruits are toxic but the fruits of the Walking Stick Palm are red and are very sweet and tasty to humans and are not toxic.  In determining the potential toxicity of wild fruits there is no easy rule to follow.  You have to rely on a knowledge of other people's experience such as whether the fruit was consumed by aboriginal people or what has been written in the various books on wild fruits.

The stage of ripeness can also be a factor in the toxicity of fruits and closely related species may also vary in their effects.  Most Lilly Pillys are edible but I know of a group of people who became ill after eating the fruit of a particular species in northern New South Wales.

Invertebrates overlooked

Female Red-backed Spider from Levenstrath
Although they make up the majority of animal species on earth the invertebrates are often overlooked when biodiversity and conservation are considered.  The invertebrates are interesting and valuable in their own right but are also important items in the food chain of many vertebrate species.  They are also essential to the pollination of plants and may have detrimental impacts as well, especially when humans have interfered with the natural balance, such as eucalypt die-back which is often caused by beetles and curl grubs.

The term bug is often applied to all insects and their relatives but this term properly applies to insects with sucking mouth parts, both carnivorous and herbivorous - order HEMIPTERA (half-wings).  Apparently 'bug' is an old English word for any strange creature which was small and, generally, unpleasant (Insects of Australia, John Goode), so we have come the full circle.  

 I have photographed a number of invertebrate species at home and at other local sites recently.  The following are photos of some of them.

If anyone knows the specific names of the Huntsman-like spider, the lacewing or the king cricket I would be keen to know.
