New work from @devisatarkar.bsky.social et al on how effects of climate variability- particularly more unusual events - depend on developmental stage & prevailing conditions in Wytham Woods great tits.

a 14 day old great tit nestling, ringed for individual identification

Figure from the paper showing that extreme climatic events interact with ambient climatic conditions and breeding timing within a season, in a developmental stage-specific manner, to influence nestling growth in great tits

New preprint! 🪶

We analysed 60 years of data on 83,000+ great tits to show how extreme climate impacts on nestling growth and survival are stage-specific and context-dependent 🐣 🌍🔥❄️

How university students work on assessment tasks with generative artificial intelligence: matters of Judgement Despite concerns about students’ use of generative AI (GenAI) in assessment, the technology has become embedded into students’ everyday assessment practices. It is unclear how students are making j...

Interesting qualitative study of generative AI use by students that shows that variation in their awareness of how much they rely on it explains their ability to either (a) use it to learn versus (b) developing dependency. www.tandfonline.com/doi/full/10....

Documentan por primera vez cómo el murciélago 'gigante' de Doñana atrapa y devora pájaros en pleno vuelo Tras décadas de intentos, un equipo liderado por la Estación Biológica de Doñana ha logrado registrar el sonido de un nóctulo grande depredando un petirrojo europeo en el aire

Han documentado por primera vez al noctulo gigante cazando un pajaro. El registro es brutal pero lo es mas cuabdo conoces a las autoras y sabes el trabajazo que ha conllevado www.eldiario.es/sociedad/doc...

I think they are rats, the tail is quite rattish, but I may be wrong. I remember the hole of the box being nibbled and enlarged. They were quite big. I am still amazed that they fitted inside and how reluctant they were to leave the nest.

I also found some pictures of not that common nest box dwellers

I needed to go through some pictures from the fieldwork I did in Corsica, and in addition to the amazing landscapes

Matching habitat choice?

I loved it!! Fun, nice pictures/videos and some peculiar people :-)

Nice morning ringing at Wytham woods

Cryptic Ontogenetic Changes in the Ventral Coloration of a Color Polymorphic Wall Lizard (Podarcis muralis) Wall lizards' ventral coloration undergoes cryptic ontogenetic color changes invisible without UV vision. We tracked wall lizards from hatching to one year of age. Spectrophotometry and visual modeli...

🧪 New paper out! Growing up, wall lizards undergo a UV-visible “awkward phase” (who doesn’t?) that we can’t see—but they can. These ontogenetic color changes may mediate juvenile–adult interactions by delaying the onset of adult social signals. doi.org/10.1002/jez.... #colsci #lizard #ontogeny

mallard with a strange colour variation, potentially a hybrid.

I found this mallard today. It seems like some kind of hybrid—if it is, is it possible to identify the species? Or is it just a chromatic aberration?

Tenemos nueva publicacion en el blog de la @eco-aeet.bsky.social de la mano de @davididiaquez.bsky.social y como siempre, animaros a participar!

Muchas gracias a @bioeaf.bsky.social y a @pulgar-panda.bsky.social por la ayuda y a la @eco-aeet.bsky.social por el blog :-)

Las condiciones ambientales y la coloración de las aves Una de las características más llamativas de las aves, además del vuelo, es su coloración. Las aves muestran una gran variabilidad tanto en el número como en la conspicuidad de los colores que tien…

Si necesitáis una lectura amena y entretenida sobre coloración y aves, he escrito una pequeña pieza para el blog de la AEET. Pido disculpas de antemano por el autobombo :-)

Enjoying this more than expected. Time to do a big year? youtu.be/zl-wAqplQAo?...

A blue tit was seen.

Nice morning at @rspbotmoor.bsky.social

🚨 PhD alert 🚨 We are looking for a highly motivated student to use 🧬 genomics 🧬 and 🛰️ bio-logging 🛰️ approaches to disentangle cultural and genetic contributions to seabird migration 🐣 Think this is you, or someone you know? Then come to our Q&A session at on 29/09 and check out the ad below!

We offer a fully funded 4-yr contract for a PhD candidate in Evolutionary Biology to join our group (www.eco-evo-devo.com). The project will combine genomics and ecophysiology to understand the evolution of developmental plasticity in spadefoot toads. For requisites and contact info please check 👇

Counting the days until the next one!

ggplot2 4.0.0 A new major version of ggplot2 has been released on CRAN. Find out what is new here.

I am beyond excited to announce that ggplot2 4.0.0 has just landed on CRAN.

It's not every day we have a new major #ggplot2 release but it is a fitting 18 year birthday present for the package.

Get an overview of the release in this blog post and be on the lookout for more in-depth posts #rstats

What a nice end for a really nice conference. Lovely time in Olomouc meeting old friends and making new. Really amazing conference @hnbirds2025.bsky.social
