Walker's Lake Bird Survey

Wednesday 20th Feb 2019 saw several members from St Arnaud Field Nats and Avon Plains Banyena Landcare Group leave the boat ramp for a round-the-Lake bird survey. Beautiful clear, sunny and cool weather kept any pesky insects at bay and we spent 2 1/2 hrs watching birds and listing them for Birdlife Australia's online Bird Atlas. Walker's Lake, north-west of St Arnaud, one of the waterbodies in the highly significant Avon Plains Lakes system.

30 species were seen, mostly waterbirds or landbirds that are associated with wetter environments such as Magpie-larks. For first part of our walk, through Black Box Woodland to the western end of the lunette, we were accompanied by a small family of Black-fronted Dotterels, moving like little clockwork toys along the insect-laden edges of the water. Moving with the BF Dots, but staying in front of the pack was a pair of Red-kneed Dotterels. You can see the red knees in this on-the- move long telephoto shot by Prue McAllister (APBLG).

Up onto the lunette( a huge sandbank, formed over thousands of years from pelleted clay blown from the lake bed during dry,cold spells) and the bird assembly changed- Welcome Swallows and White-plumed Honeyeaters foraged busily above or in the massive Redgums, Galahs and Long-billed Corellas defended their nesting areas; the Redgums are full of hollows, indicating their great age (150 year of growth before hollows begin to form). From our vantage point we spied a raft of Australasian Darters, diving and fishing in the shallow waters, almost like a choreographed water ballet- all up, then one after the other, down again! It was hard to count how many there were. Male Darter in breeding array Photo A Hughes StAFNC

Several smallish rafts of ducks were seen a good distance away- photos later revealed Pacific Black Ducks, Grey Teal, one lonely Hardhead, the pretty little Pink-eared Ducks and wonder of wonders, a group of 4 Australasian Shovelers, a protected species during the duck shooting season, and not unlike the Pinkies in profile( strange bills) but larger and with more distinguishing marks- white patch and dark rump. This group included 3 males and one female and the very long shot was taken again, by Prue McAllister.

Moving along the southern shore, through the Redgums and Black Box, we spotted 4 White-breasted Woodswallows using the fenceposts as perches.

They were not interested in posing for the cameras but the photos were good enough for identification purposes. White-breasted Woodswallows are seen at the Lake mostly during Summer.

This pair behaved like juveniles, waiting for parents to return with a meal.

Food was certainly on our minds as we completed the 3km walk and headed for our morning tea- the usual relaxed and enjoyable end to our outings at the lake.

Small Milkwort Monitoring Results

Small Milkwort (Comesperma polygaloides) is listed as threat- ened under Victoria's Flora and Fauna Guarantee Act(1988) and described as "an uncommon component of the grassy woodlands of the Wimmera, extending east to the Bendigo area"

Once widespread it is now confined to a few scattered patches across the inland slopes of Victoria with only a few plants known from our region.

2018 Roundup

The last job of the year, 29th December - monitoring of our 2 Small Milkwort (SM) Plots in the Kara Kara National Park. Both plots are very dry and show signs of incursions by wallabies and kangaroos- scrapes, hip hollows, pruning and droppings. The larger plot had 58 spikes ( we believe that each rootstock puts up multiple stems and it is hard to decide where each plant starts and ends). There were only 7 flowering spikes in contrast to 24 last year; the spikes were very small and the flowers miserable! Most plants were less than 5cm tall.

On a brighter note, the Eutaxia microphylla and Templetonia stenophylla are doing very well- both are members of the pea family and are very palatable to browsers and grazers so the protection offered by our fence has proved its worth there. Leafy Templetonia- T. stenophylla flowers and leaves

Common Eutaxia- E. microphylla

The second plot, also known as the "Small Small Milkwort Plot" is also having problems with wallabies- the Peach Heath looked as if a mower had been over it and ditto the Small Milkwort. Only 1 flower spike out of 48 plants was found. A new colony of SM was found in 2016 and is persisting - 7 stems but no flowering spikes. It is likely that more SM is out there but the smallness of the plants, and near-impossibility of seeing them unless they are flowering makes this plant difficult to find.

Summer, grass-seeds, mosquitoes and heat all combine to make searching for it quite a task. Monitoring data for this project will soon be on our website. The Yellow Gums in both plots have been flowering and are now getting ready to shed their bark- the colours are astounding.
