Twitching Sunshine Coast Kentish Plover & Asian Gull-billed Tern

Kentish Plover

It's been a good week for twitching around the Sunshine Coast. Jane Cooksley made a fantastic discovery late yesterday afternoon when she found a Kentish Plover at Noosa. The bird was on a sandflat in the Noosa River about 1.5km upstream from the river mouth at low tide opposite Noosa River Holiday Park at Munna Point. The Noosa River has had its share of rarities in the past, including Queensland's only Hooded Plover.

Jane and her hubby Andrew had been walking the sandflats after disembarking from the family dinghy. Jane and Andrew kindly offered to take Carolyn Scott and I out today in an upgraded family boat! With a king high tide scheduled for 8am and the river sandflats under water, the initial plan was to head out in the afternoon at low tide. However, Andy Jensen spotted the bird early this morning from the river's south bank; it was distantly on a sandbar on what was almost certainly the island that hosts nesting Beach Stone-Curlews.

So we opted for an early morning high tide search instead. We landed on the island but no Kentish Plover, just a couple of Red-capped Plovers and loads of terns. Then Rob Morris subsequently saw the bird close to the river mouth (the joys of Facebook instant messaging) so we headed to the north shore and disembarked; it's likely the plover and other birds had been flushed from the island by a visiting kayaker. Carolyn spotted the plover along the high tide line. The bird was associating loosely with a flock of about 20 Red-capped Plovers and was immediately very different in appearance.

The north shore can be accessed by road after crossing the Noosa River by vehicular ferry at Tewantin. Non-4WD vehicles can drive to the end of Esplanade/Flying Fish Track/Wilderness Track (called various things on different maps), which runs along the river's north shore off Beach Road. Vehicles can be left in the bush there and you can walk 1km to the river mouth. We saw the bird at high tide. If it moves back into the river as the tide recedes, you can generally walk the sandflats at low tide, although they cover an extensive area. Sometimes low tide is not particularly low, in which case a boat would be needed to access the sandflats. Or you can be satisfied with more distant views from shore.

Last Tuesday, Helen Leonard found an (Asian) Gull-billed Tern at the Toorbul high tide shorebird roost. This species, affinis, was split recently from what is now known as the Australian (Gull-billed) Tern macrotarsa. I looked for the bird without success at Toorbul on Wednesday but found an Asian Gull-billed Tern hawking the mudflats of Godwin Beach on a receding tide later during the day.

Later in the week, Helen photographed an Asian Gull-billed Tern at the shorebird high tide roost of Kakadu on Bribie Island. It's likely these three sightings are of the same bird. It is possibly the same bird that has been seen several times in recent weeks in the Pine Rivers area a little further south. While not of the same vintage as a Kentish Plover, this is another scarce visitor to these shores from distant lands.

West Coolum Wetland to be Protected

West Coolum Wetland

The West Coolum Wetland on Queensland's Sunshine Coast is to be protected and managed as a nature reserve in a significant win for the environment. The decision by the Sunshine Coast Council at its February meeting to protect the 90-hectare site means more than 700 hectares of contiguous wetland and coastal woodland in the heart of the Sunshine Coast will be preserved.

The West Coolum Wetland is on land formerly used for sugar cane production. The area was inundated by tidal flows from Coolum Creek following the collapse of canal floodgates after the council acquired the site in 2011, allowing a thriving wetland to be created in the same way that the nearby Yandina Creek Wetland came to be.

Broken floodgates at West Coolum Wetland

The 190-hectare Yandina Creek Wetland was drained and earmarked for development before it was acquired by Unitywater in 2016 as part of the corporation's nutrient offsets program following a lengthy campaign to save the wetland. The site has been restored as a flourishing wetland and the numerous birds that had called it home are returning. Prior to Unitywater's intervention, the Sunshine Coast Council came under fire for rejecting proposals to purchase the land and restore the wetland.

The council has since demonstrated an encouraging change of heart. Last year it launched its Blue Heart Sunshine Coast Project, aiming to sustainably manage 5,000 hectares of the Maroochy River floodplain in partnership with Unitywater and the Queensland Department of Environment and Science. The project's objectives include the securing and protection and management of the floodplain's most environmentally critical areas.

The council will play a role in the future management of the Yandina Creek Wetland as part of its Blue Heart commitment. The move to protect the West Coolum Wetland, which had partly been designated for “open space sport development”, is another important step. Yandina Creek Wetland, the Coolum Creek Reserve and West Coolum Wetland are now joined in a large protected area.

I stumbled upon the West Coolum Wetland while kayaking along Coolum Creek in 2016. I was immediately impressed with its potential as a reserve and wrote to the council requesting that it be protected as a wetland. Among nice bird records there were one of only two sightings of Australian Spotted Crake from the Sunshine Coast region, and the scarce Eastern Grass Owl and Australian Little Bittern. The council undertook environmental consultancy studies which indeed underscored the site's environmental values.

Sunshine Coast Mayor Mark Jamieson said the wetland would be managed for conservation and added to council’s environment reserve network. “The lands, located west of the Sunshine Motorway at Coolum Beach, offer an exciting opportunity to establish an estuarine wetland due to the frequent tidal inundation of the site,” the mayor said.

Speaking more generally about Blue Heart, Mark Jamieson said: “The project is a fantastic example of how council is taking action now to identify risks, and help our community prepare for the impacts of a changing climate. Working across approximately 5000 hectares on the Maroochy floodplain, the project seeks to deliver effective land and water management to proactively respond to a transitioning landscape through conservation, recreation, flood mitigation and new carbon storage opportunities.”

As with Yandina Creek Wetland, there is no public access to West Coolum Wetland. Unitywater has given repeated undertakings to eventually allow pubic access to Yandina Creek. The council is expected to take the same approach with West Coolum.

One pressing problem facing the Maroochy River floodplain remains, however. As I have written previously, the council has allowed the residential subdivision of sugar cane farms on the floodplain in contravention of state government and council planning guidelines. As a consequence, extensive areas of cane and grassland that are home to an abundance of birdlife are being carved up for homes that must surely be flood-prone.

Rescue Mission for Endangered Eastern Bristlebird

Eastern Bristlebird

In a sign of what we are rapidly coming to appreciate is the “new normal” of severe climatic events in Australia, an extraordinary operation is underway to rescue a remnant population of the endangered Eastern Bristlebird from the bushfires which have been ravaging south-eastern Australia for the past five months.

The unprecedented rescue operation involves the Australian Defence Force, Zoos Victoria, Parks Victoria, Queensland's Currumbin Sanctuary, Monash and Wollongong universities, the Orbost Incident Management Team, and the Victorian Department of Environment, Land, Water and Planning.

Leading the charge in the field is Monash University's Rohan Clarke. Rohan has written on Facebook of the efforts of a team of people working to save the Howe Flat population of Eastern Bristlebird. The birds are at risk of being consumed by fires which have devastated the nearby town of Mallacoota and hundreds of thousands of hectares of bushland across four states. About 180 bristlebirds frequent the threatened site.

Chinook helicopter to the rescue

Seven rescuers were taken to the area in an ADF Chinook helicopter after flying from Melbourne to Sale. The biodiversity hotspot is threatened by fires burning to the north of Howe Flat – near Marshmead and the Victoria-NSW border in Nadgee Nature Reserve. Says Rohan: “The operation is likely unprecedented both in terms of the action – rescuing an endangered species ahead of an approaching fire – and the level of support provided. My role is to lead a catch team alongside Rowan Mott and people from Zoos Victoria, Parks Victoria and DEWLP.”

Rohan checks the mist-nets

Birds are snared in mist-nets, with 15 having been caught by Wednesday night. With two birds per containment cage, the precious cargo is taken by boat to Mallacoota and then by charter flight to Melbourne Zoo. The best outcome for all concerned is that Howe Flat doesn't burn and the birds can be released back there when the danger is over. Rohan says that alternatively, if the worst happens, a captive insurance population can be used to rebuild the southern population as conditions recover. He adds: “Nestled within this is a positive story where a collection of agencies and organisations and an impressive group of people (both those on the ground but also critically those behind the scenes that just make things happen) have been working together to achieve this.”

Says Victorian Environment Minister Lily D’Ambrosio: “Our hardworking teams are ensuring this precious little bird has a chance at a bright future despite the impact of these devastating fires, which are still posing a threat to our native wildlife.”

Captured bristlebirds head to safety

With 15 birds in protection, the first phase of the mission is completed; the target had been between 15 and 20. Says Rohan: "There's still lots of hard work ahead. People remain on the ground fighting the fires to protect assets such as the incredible biodiversity at Howe Flat.  Zoos Victoria is pulling out all stops to house and support a very special bird. Work is underway to plan and implement the next steps that will aid with recovery this species and others impacted by the fires."

Eastern Bristlebirds can breed successfully in captivity. Currumbin Sanctuary has bred several pairs of the critically endangered northern population that frequents the NSW-Queensland border area. That population is likely to have been hit by fires which raced through its distributional range last September. About half the territory of one pair I've been monitoring for several years has burned.

By some estimates, as many as one billion wild animals have perished in the bushfires.
