Two American sparrows with similar mtDNA: Rapid speciation or hybridization?
Analyses of the nuclear genome provide the answer to this question.

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.

These wetlands provide important habitat for #endangered and #protected species 𓅰 𓅬 𓅭 𓅮 𓅯
Development can co-exist and enhance bird habitat and is doing so here. Monitoring will continue to ensure this lasts!

Thank you 💫 Any questions?

New paper: Female superb lyrebirds show diverse vocal mimicry unrelated to age, but older females more often mimic predators, suggesting mimicry is fine-tuned for nest defence rather than sexual selection.

Female superb lyrebird. Photo: Wikimedia commons Fig. 4 from the article: Duration of element types with age. Ambiguous elements were significantly shorter in older females than younger females. By contrast, effects of age on conspecific and mimetic element length were not significant.

Waders/shorebirds have relatively high annual survival (and low productivity).
Bird ringing/banding is key to mearsuring survival.
When a survival rate falls it can have a rapid impact on population level.

Biodiversity is declining rapidly 🌍📉 — but our ability to measure life on Earth is advancing faster than ever.
A new paper by Sutherland and colleagues outlines Nine changes needed to transform how we monitor biodiversity and guide conservation decisions.
📄 Sutherland et al. 2026 👉 lnkd.in/g5nsc2qk
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.

We still have 2 feet of snow on the ground, but bald eagles down the street are back from their winter vacation. They've been using this nest for a few years now. #birds 🌿
Two adult bald eagles with their white heads and dark brown bodies perch on their huge stick next in the high crotch of an aspen tree. The image is in the blood mood of late evening.

Our new paper is out: "Acoustic differences persist in urban Parus major (Great Tit) over two decades of declining anthropogenic noise in Paris, France."
A study of noise and bird song, by me and Hans Slabbekoorn, in Ornithological Applications @amornith.bsky.social:
doi.org/10.1093/orni...
An infographic summarizing the key findings of the new paper "Acoustic differences persist in urban Parus major (Great Tit) over two decades of declining anthropogenic noise in Paris, France" by Dan Mennill and Hans Slabbekoorn. A cartoon image shows a sound recordist recording a Great Tit on a street in Paris. One inset graph shows that noise levels in Paris have declined from 2008 to 2023. A second inset graph shows that Great Tits sing at higher song frequencies when the ambient environment is louder. A third inset graph shows that Great Tits continue to sing higher-freuqency songs in 2023 versus 2003; even though Paris is growing quieter, Great Tits in Paris sing higher frequency songs than quiet forests outside of Paris.

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?)
