New research sheds light on geographic patterns in shorebird size and shape

New research sheds light on geographic patterns in shorebird size and shape, thanks to long-term data collected by the Victorian Wader Study Group and Australasian Wader Studies Group.

We show that shorebirds from hot, tropical north-western Australia are smaller and have longer bills than members of the same species from temperate, south-eastern Australia. These patterns are consistent across 30 ecologically diverse species, including sandpipers, plovers, terns, stilts, and oystercatchers.
Differences in the size and shape of shorebirds from northern and southern Australia correspond with two eco-geographic ‘rules’ in ecology. Bergmann’s Rule states that animals should be larger at higher latitudes, while Allen’s Rule states that animals should have shorter appendages – such as bird bills – at higher latitudes. Understanding why latitudinal patterns in animal size and shape exist is challenging because there are many possible explanations.

Our findings best support the expectation that differences in shorebird size and shape are driven by adaption to keep cool on the northern Australian coast. This would explain why Arctic-breeding shorebirds that travel to northern Australia have smaller bodies and longer bills than members of the same species that fly to southern Australia. It also explains why we find consistent patterns in body size and bill length across migratory and resident shorebirds. Small bodies and long bills help birds keep cool by providing a greater surface area to dissipate heat. Longer bills are especially advantageous because birds can increase blood flow to the bill’s surface to increase heat loss.

This research helps improve our understanding of the evolution of shorebird size and shape, and how shorebirds might adapt to a warming climate.

Australasian Shorebird Conference online in 2022

The 12th Australasian Shorebird Conference will take place from 29-30 October 2022 hosted jointly by the Australasian Wader Studies Group and the Queensland Wader Studies Group. We are pleased to announce that the Conference will be an online event, in the hope of encouraging broad participation from around Australia and across the East Asian – Australasian Flyway Partnership.

The theme for this Conference is “Global Strategies Local Actions” and through the Conference program we will look at what has been happening across the East Asian – Australasian Flyway since the 11th Australasian Shorebird Conference held in 2018.

The call for abstracts for the Australasian Shorebird Conference 2022 is now open. You can submit an abstracts for an oral presentation (15-min talk, plus 5-min for questions), or an e-poster presentation. Abstracts can either be submitted under the following themes or as general submissions.

  • EAAF site network
  • Conservation and monitoring
  • Citizen science
  • Indigenous research, monitoring and conservation
  • Communicating shorebird science

All submissions will be considered for the program and program sessions will be determined on the basis of submitted abstract themes.

Go to the Australasian Shorebird Conference website to find out more and submit your abstract.

Sanderling sightings from China

Several Sanderling tagged in South Australia and south-west Victoria in April 2022 have been sighted in China during the May field work season. Noteable resightings include LHL, BCE and BVM at Guangdong, and LEY at Wanbao beach, Shandong. LEY is the exciting observation having been first captured in April 2014 in Nene Valley.

You can view Sanderling sightings on the BirdMark portal, where you can also submit your own sightings.

Vale John Stoate

John died on March 17th at the age of 93. John leased and then owned Anna Plains Cattle Station, south of Broome. This abuts the Eighty Mile Beach Ramsar site, which is a major hot spot for migratory waders.

The AWSG has been visiting Anna Plains Station for many years, thanks to John’s interest in these birds and the great friendship he and Clive Minton struck up. The AWSG camped on the station around the homestead for many years with the help and support of John, and in later years his son David and his wife Helen Campion. John’s eyesight faded in his last few years, and he was unable to enjoy the trips to the beach, especially with Clive, despite this he took an active interest in our activities and the running of the station. When the AWSG was at Anna Plains John and Clive met every evening to enjoy a port, a chat and probably a snooze in front of the television.

Many people have joined the expeditions to Broome over the years and we have all had a wonderful time using the facilities of the station, and camping near the main homestead. John and his family have always been very welcoming to our annual invasion of their homestead area. Visiting a cattle station has been an interesting experience for our overseas visitors, as well as Australian participants, and we were always given the opportunity to explore the station, admire the cattle and hunt for wildlife. I enjoyed evening chats on the verandah with John in 2020 when Clive was no longer with us. Covid has unfortunately prevented most of us visiting for 2 years. John will be missed, as a wonderful supporter of our work with the shorebirds, as well as great family man and contributor to the cattle industry.

Sanderling highlights March 2022

Sanderling continue to be seen regularly in the South Australian section of Discovery Bay. Many of the flags recorded by observers are of individuals captured at Yambuck in early December 2021. Sanderling have been absent from the Nene Valley beach all season until the last few weeks 1 or 2 have occasionally been seen. On Saturday 19th March, a small group of 20-30 was sighted, including BMZ – yet another Yambuck individual.

Going further to the west we have had sightings from Little Rock and Pethers in Canunda. On 14th March, BKE was sighted – originally flagged at Yambuck, then seen by at Danger Point on 3rd March.

So, now we need some sightings from the Coorong! With Coorong the Park of the Month during March, and a Shorebirds activity on the 26th, fingers crossed we get some more sightings.

Congratulations to Sarah Campbell on winning the February Sanderling award of a print with this stunning photo of Sanderling BJH taken in Riddock Bay. BJH was originally flagged in the early December catch at Yambuck.

Saturday 9th & Sunday 10th April were the last days in the field. The catching team has had variable success. The high note is that all 30 geolocators were deployed. The low note is that only one has been retrieved. This despite the fact that birds bearing geolocators have been observed at all catching sites, e.g. VAZ (aka ATZ) has been seen several times at Nene Valley west.

You can learn more about the Sanderling tracking project on the Glenelg Hopkins CMA website.

Recent wader sightings

There’s been some great observations recently from south-west Victoria and south-east South Australia.

The first was by Maureen Christie of some of the sanderling tagged late last year at Yambuk and Pethers, as part of the Sanderling tracking project.

The other was some fabulous pied oystercatcher sightings from the Coorong in January by Mary-Ann Van Trigt.

Thanks to Maureen and Mary-Ann for sharing these photos.

10 years on Thompson Beach godwits are still using Bald Hill in South Australia

Bar-tailed Godwits CAH, AKK, AHZ were photographed by Paul Taylor at Bald Hill on the 15/12/2021. He saw all three birds there in December 2020 as well. The three godwits were originally banded at Thompsons Beach, CAH on 23/11/2013 and the other two 29/11/2012.

AKK has featured previously in the news as our local frequent flyer. Fabulous to see these birds back again.

Thanks to Paul Taylor for permission to use these photos.
