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.

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...

Our research on waterbird ecology in the rice fields of the Tagus river basin made the cover of Hydrobiologia. You can read the paper here:

A cool figure in

. 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?

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...

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. 🔗

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...

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)
