New paper: do GPS tags affect small shorebirds? In Kentish plovers, solar-powered devices showed no detectable effects on behaviour, reproduction, or short-term survival.

Development can co-exist and enhance bird habitat and is doing so here. Monitoring will continue to ensure this lasts!

Thank you 💫 Any questions?

Four-panel collage showing biodiversity across ecosystems. Top left: a reindeer grazing in snow. Top right: a colorful coral reef underwater. Bottom left: a jaguar walking through dense green vegetation. Bottom right: tall desert cacti in an arid landscape. Overlaid text reads: “Biodiversity is in rapid and widespread decline. This paper outlines nine urgent changes needed to transform how we measure life on Earth and guide conservation and policy.” A white arrow in the bottom right corner points forward, indicating the next slide.

A scientist wearing a blue glove collects a water sample from a rocky stream while kneeling outdoors. Overlaid text reads: “We are entering a new era of biodiversity measurement: • eDNA from water, soil, and air • Reference genomes at scale • AI image and acoustic monitoring • High-resolution satellite sensing • Billions of citizen science records The opportunity is extraordinary — if we build the right systems.” A white arrow at the bottom right indicates the next slide.

Biodiversity is declining rapidly 🌍📉 — but our ability to measure life on Earth is advancing faster than ever.

Looking for a postdoc on bird migration and have computer science or remote sensing skill? 🌍 🧪 🦑 #Ornithology

We need to correct (and further improve) the maps for two sister South American thrushes: Hauxwell’s and Cocoa.

Dear bird recordists: please pay attention to calls, too - they allow species recognition way better than songs in this case (and in thrushes and maybe Oscines in general?)
