Can remote sound recorders help with surveys of breeding waders?

Paper just out in @IBIS_journal - data from acoustic recorders and an AI classifier can be better than transect survey data at predicting relative densities of Curlew and Oystercatcher (but not Golden Plover or Lapwing) across an upland study site.

"It’s likely that public opinion is quietly, calmly against the idea of a National Park in Galloway – but it’ll be interesting to watch the debate unfold if the current battleline of “retired people vs furious farmers” is allowed to deepen & heat up" gallowayfarm.blog/2024/07/30…
Sandpipers, plovers, geology and a long-lost football pitch at a former opencast mine site in East Ayrshire:

Reducing predation is crucial for Curlew recovery. Learning how nest survival and predator identity varies between areas is important for getting interventions right. The images show a stoat predating a Curlew nest monitored this season by @_BTO for the CST project
Surely the big question here is whether the adults will be able to find enough food to successfully raise young on an artificial pitch - are there grass pitches nearby?

Flat gravel roofs and proximity to grass sports pitches result in high reproductive success for Oystercatchers - but in this case is the 3G pitch an ecological trap? @ForWaders

Check this out - an excellent #WorkingforWaders blog from David summarising the many issues facing waders in Scotland today. @ScotGamekeepers @CurlewAction
Tipping Points: is it time for new approach to wader conservation? “We need to communicate honestly and openly about the scale of the challenges and what the realistic endpoints might be” - Guest blog by @DavidJarrett4 workingforwaders.com/blog/20…

Another good blog on the challenges & nuanced debate required around protecting in particular ground nesting birds. We need to put aside our differences if we are going to solve this dilemma. I would like to see private & NGO working together to agreed priorities in an area.
At the recent @CurlewAction conference there was much consensus about the importance of communicating openly about predation, so here's a blog post discussing Badgers and ground-nesting birds:

We categorised studies based on the metric they produced: i) "Hatching Success" - the % of nests that hatch; ii) "Fledging Success" - the % of pairs that fledge any number of young; & iii) Young Fledged per Pair - the total number of young fledging. 4/6
Factors which influenced study design included vegetation structure (which determines whether broods are countable), re-laying rates, whether the target species exhibits diagnostic behaviour at the nest and chick stages, and the availability of skilled fieldworkers. 5/6
The paper is free to access at Ibis at that link - the peer review and editorial process was excellent and improved the original draft enormously (thanks!). 6/6

This paper entitled "Monitoring Wader Breeding Productivity" where we reviewed methods used to monitor productivity was recently published (early view) at @IBIS_journal 1/6

Across Europe, wader populations are crashing, associated with low breeding productivity caused by predation, and agricultural activities destroying nests or killing chicks. Most national bird monitoring schemes are only able to monitor presence, and not productivity. 2/6

The spring-fed peat bogs between Codroipo & Palmanova (Udine) are a jewel in the biodiversity crown of @regioneFVGit but threatened by invasive scrub, esp. Alder Buckthorn. This weekend, (as in 2022 & 2023), with no wind & dry conditions, the Region's Biodiversity Service, 1/x – at Friuli-Venezia Giulia, Italy

I feel so conflicted as a grassland ecologist abt the latest Crowther antics; namely, this piece about his supposed "remorse" over his trillion trees paper. On the one hand: great, you're combating your own misinfo. On the other: maybe retract the paper instead of doing PR?
Ecologist Thomas Crowther’s research inspired countless tree-planting campaigns, greenwashing, and attacks from scientists. Now he’s back with a new plan for nature restoration. wired.trib.al/TG1Y4n4
