There is much scope in combining Earth observations with Down-to-Earth observations of tracked #shorebirds. We developed a very satisfactory LAND USE INTENSITY metric based on @Sentinel1a explaining godwit distributions. besjournals.onlinelibrary.wiley.com/doi/full/10.11… @ESA_EO @esa

We were able to show the value of both this new LAND USE INTENSITY metric as well as distribution of tagged godwits during hot dry summer of 2018, when much of what is now evergreen pasture turned brown. #climatechange #Dairy @RuthHowison @DairyCampus

Distribution of tagged black-tailed #godwits in early summer was better predictor of #drought damage than land use intensity. Interpretation: #grutto's select intact #soils with capillary connections with #groundwater. #meadowbirds #sentinels @WaderStudy

Hi shorebird folks! 1more4U2go! Migratory shorebirds connect. Movements, presence & phenotypes signal the state of habitats. Let's develop tracked individual migratory birds as sentinels (of connected parts) of Earth. #ornithology #globalchange @WaderStudy

Recently, 100 units of fossil energy produced 104 energy units of food, thanks soil-based processes. Now, 100 units fossil energy yield 16 food units, the 84% loss equals release of CO2 & active nitrogen threatening climate & biodiversity. #globalchange #dairy

Looking at scale of a country then, steep decline of specialized #dairy #farmland #wader, black-tailed #godwit (#grutto) in Netherlands signals growth of unsustainable, climate & biodiversity threatening, practices in agriculture. #globalchange @WaderStudy

1⃣ #ISTC20 #Sesh8 👋I'm a PhD candidate exploring #shorebird communication across the eggshell in Melbourne, Australia. Some avian embryos can begin calling late in incubation and can communicate with parents through the eggshell🥚Have a listen to these embryonic calls, below!

Knowing where (how high) birds fly in the air is important in this changing world. Because we have windfarms, airplanes, and tall buildings, all of which have the potential to impact the flight altitude of avian migrants. #ornithology #ClimateChange

1/6 140 VWSG volunteers have been monitoring waders in SE Aus for 40 years. We have several important sites around Victoria, Tas & S. Australia for catching and banding waders. Data are used for pop monitoring, migration route, survival and repro rate assessment

1/6 We know very little about viruses in #shorebirds. They are important in the epidemiology of some viruses (influenza, coronavirus), but many viruses to be discovered in this host group

2/6 Shorebirds are a central reservoir host for low pathogenic avian influenza virus globally (these viruses don't cause disease).
Some species, like Ruddy Turnstone have high levels of seroprevalence. In Aus, varying levels of infection across shorebird species

3/6 #Shorebirds are important reservoirs for a diversity of coronaviruses (different from COVID). Prevalence in Aus is comparable to influenza. We have also described a new coronavirus, currently only found in Aus shorebirds

1 #ISTC20 Low reproductive success threatens long-term viability of many #shorebird populations. Hooded Plovers (aka hoodies) are highly threatened #BeachNestingBirds along AUS southern coast and impacted by threats like human disturbance and introduced & superabundant predators.
2 #ISTC20 Threats’ impact on egg & chick survival is poorly understood. We set up remote-sensing cameras on 81 Hoodie clutches along the Victorian coast to confirm nest fate, and radio-tagged 27 Hoodie chicks (from 27 broods) to monitor survival and determine causes of mortality.
3 #ISTC20 Threats' impact on egg and chick survival is poorly understood. We set up remote-sensing cameras on 81 Hoodie clutches to confirm nest fate, and radio-tagged 27 Hoodie chicks (+22 untagged siblings were monitored) to monitor survival and determine causes of mortality.
1 #ISTC20 Monitoring from 1980 onwards revealed a decline in Hooded Plover population along Victorian coast (southern Australia). From 2006, @birdlifeoz runs a broad-scale adaptive management project to improve this declining trajectory by managing threats to breeding birds.
2 #ISTC20 We identified human disturbance and invasive predators as major threats. Our objectives are to ⬆️breeding success to ⬆️population & protect habitat. >500 trained #CitizenScientists monitor breeding Hooded Plover pairs across ~300 sites in Victoria and South Australia.
3 #ISTC20 Taking the Bellarine Pen & Surf Coast as an example, within 12 years of recovery effort, the population has increased from 9 to 22 breeding pairs. Working with land managers & volunteers, we’re protecting 22 breeding sites via on-ground actions, education & regulations.
1 #ISTC20 #Sesh7 OK here’s a thread on #languagebarriers. Yes you are in the right conference. This is still about shorebirds. What I mean is I will explain how language barriers can affect the conservation of shorebirds (or any other species). So don’t leave! #ornithology
#ISTC20 #Sesh7 I will also tweet the same content in Japanese during the break after Session 7. Sadly I am not fluent enough to tweet in other languages, but feel free to translate my tweets into any language! セッション７後の休憩時間中に日本語でもツイートしますのでご覧ください。
2 #ISTC20 #Sesh7 So, why languages? Shorebirds’ incredible migration (image: @GlobalFlyway) means their annual cycles span across multiple countries, and this poses a challenge to conservation, as we need to coordinate across countries, where the language is often different.
#ISTC20 #Sesh5 1/16 I thank the organisers for a chance to present my research here. I work on the Spoon-billed sandpiper (SBS), a charismatic species, characterised by an unusual shape of its beak. It is also critically endangered, with <200 pairs left in the wild.
1/21 #ISTC20 Hello to all! It’s a pleasure to greet you from Santiago de Chile and share the experiences and perspectives of @WHSRN @ManometCenter with participants in the International Shorebird Twitter Conference 2020 #Sesh4
1/23 Thanks first to organizers of this new age conference, for inviting me to join in. I am very excited to be here with shorebird researchers from around the Twitter and real worlds #ISTC20 #SESH3 #ornithology #Waders
1 #ISTC20 #Sesh2 Hi everyone! Migratory ranges emerge from individual journeys between breeding and winter sites each year. Tracking these individual journeys in space and time can help us understand how migratory ranges form and change wadertales.wordpress.com/2019/07/29/gen… #ornithology
2 #ISTC20 #Sesh2 Since the 1990s, and with an amazing network of observers (‘godwiteers’), we have marked thousands of Icelandic black-tailed godwits and tracked them on their annual journeys between Iceland and W Europe wadertales.wordpress.com/2015/10/06/the… #ornithology
3 #ISTC20 #Sesh2 The breeding and winter ranges of Icelandic godwits have expanded northwards, but have these changes involved (a) individuals shifting sites or (b) generational change, with new generations occupying different sites? besjournals.onlinelibrary.wiley.com/doi/full/10.11… #ornithology
1 #ISTC20 #Sesh1 #ornithology Hello everyone. Thanks for the organizer of ISTC and Ryan. You can find my detailed information at researchgate.net/profile/Zhijun…. It’s my great honor to share the study of my team on shorebirds and their habitats in the Yellow Sea in China.
