Storm-induced mass mortality results in both immediate and long-term consequences for a migratory songbird Nature Ecology & Evolution - Combining 27 years of citizen science data with whole-genome sequencing, the authors show that mass mortality of purple martins caused by a severe winter...

Spring is arriving, but there's still snow in the forecast! How do late #winter storms affect our migratory #birds? Out now in @natecoevo.nature.com, we ask that Q with 25+yrs of #CitizenScience data and ~400 museum specimens collected after the 2021 Great TX Freeze: rdcu.be/e7aUy

⚠️La ciencia denuncia el uso interesado y fraudulento de supuestos estudios científicos para intentar reabrir la captura de aves silvestres, en particular de fringílidos, como el jilguero #AvedelAño.

Flexibility in the face of climate change? A rapid and dramatic shift towards later spring migration in Hudsonian godwits (Limosa haemastica) | Proceedings of the Royal Society B: Biological Sciences With rapid environmental change, shifts in migration timing are vitally important for population stability in migratory species and have been widely documented. However, little remains known about how...

1/Spring bird migration is getting earlier, right? Not necessarily! In our latest paper, led by former lab MSc student Lauren Puleo, we found that a population of Hudsonian Godwits breeding in Alaska is now arriving 6 days later than they were a decade ago. royalsocietypublishing.org/doi/10.1098/...

A cool figure in doi.org/10.1002/ece3... is the "maximum clade credibility" tree for 37 Australian shorebird species included in the study. The colours of dots at the ends of branches indicate the 3 types of non-breeding habitats distinguished. Images from field guide of Menkhorst et al. (2017).

More than two decades in the making! Well worth it.
The new question is: Why do migratory #shorebirds frequenting coastal non-breeding habitats delay #maturity (expressed in age of first return #migration) more than species using inland freshwater habitats?

The Evolution of Homeothermic Endothermy via Life History Optimization | The American Naturalist Abstract Endothermy is an energetically expensive trait, yet it has posed an evolutionary advantage across different lineages—a paradox that remains puzzling to biologists. Here, I investigate whether...

Migratory Birds Advance Spring Arrival and Egg‐Laying in the Arctic, Mostly by Travelling Faster A warming climate is affecting the phenology of life on earth, including when birds migrate and start breeding. We show that earlier arrival is a general pattern also for birds travelling to the Arct...

🚨Publication in @globalchangebio.bsky.social by Lameris et al.

→ Early snowmelt = earlier egg-laying, but only 2 waterfowl arrived earlier.
→ Over time, most arrived earlier—regardless of snowmelt or laying.
→ Why? Faster migration: shorter stopovers = earlier arrival.

Today, Jesús Carriön photographed black-ailed #godwit WARNSERPOLDER in flight at L'Albufera wetland comples near Valencia, Spain. Too bad transmitter has been dead for 2 years now, but the good news is that the #skries #grutto is perfectly alive!

We've reached 1.5°C global warming.
With current policies, we're heading for a catastrophic 2.7°C warming.
A new review paper in Science shows: this would change the Arctic 'beyond recognition', with knock-on effects (like rising seas) around the world. 🌊

New paper! @jappliedecology.bsky.social
https://bit.ly/3C5gYJp
We mapped out the migrations of over 10K ind ⚫-tailed godwits (!) to characterize connectivity between sites in Europe and Africa.
We compiled tracking data, ring recoveries and resightings: >400K records in total! (1/5)
