Very glad to see the second chapter of my PhD published in JEB and feel honored that it has been picked as this month's issue "Editor's choice" and cover image! It's been a long and important team effort leading up to these results!

Using @euring.bsky.social Constant Effort Site data spanning 12 countries across Europe we explore geographic and temporal variation in synchrony in counts, productivity and survival rates.

Another birding paper! 🐦Where do the Nearctic landbirds that show up in Europe each autumn come from? We usually assume they come from NE populations, pushed off course by bad weather - but is that the whole story? #ornithology 1/3

Whereas first arrival has advanced over the long-term study, first laying hasn't (and the same holds true when we look at the averages). Still, 2025 is a fairly early year, as there are only 8 years with an earlier first egg versus 23 with a later first egg. #phenology #seabirds

Birding paper! In the last Dutch Birding issue, we published a detailed paper on the ID of Great Egret taxa in non-breeding plumage. We analyzed photos of hundreds of individuals to find key criteria distinguishing the four taxa. A short illustrated summary can be found in this thread. #birding

Two hybrid Coenonympha species inherited most of their genome from one parent species but prefer mating with the other! By analyzing chemical profiles, we show that non-random trait sorting likely drives reproductive isolation, fueling hybrid speciation

🔍 Key insights:

✅ The proportion of juveniles over time can provide reliable estimates of mean laying dates and reproductive success.

✅ Multi-site analyses suggest that 4–5 sampling sessions per season offer a good balance between effort and accuracy.

How can we infer breeding phenology and reproductive success from bird counts or captures?
We developed a model linking juvenile proportion in populations to reproductive timing and success.

In our latest preprint, we showcase how to use a phylogenetic meta-analysis of variance to test evolutionary hypotheses across species.

We collected data for 172 birds (314 populations) to test patterns of stabilising selection and canalisation for wing length.

species are on the move in many places due to climate change

we wrote a paper arguing that we need to focus more on the *types* of movements we are seeing, as true range shifts have really different consequences from say range expansions

In nature, organisms are not only subjected to variation in temperature but e....
