Field season on common cuckoos had an incredible start! We captured 12 individuals, incl. 2 stunning rufous females. Take a look and if you're eager to learn more about the genetic makeup behind the polymorphism of cuckoo females, check our latest paper: science.org/doi/10.1126/scia…

Stoked this is published! Collect feathers > chop into tiny pieces > set them on fire > measure the gasses*. Differences in adults. Now just a small task of learning geographic assignment using multi-isotope isoscapes paired with geolocator data & larger sample size! Let’s gooo!

The Czech government sets a great example in supporting research! A new type of project funding has been launched. Restart Grants will allow female and male scientists to restart their careers after a break for parental leave! 👏👍 gacr.cz/en/restart-grants-to… @CzechAcademy @ivb_cas

Want to know how divorce in birds is associated with rainfall? 💔🌧️ I wrote a piece (in non-scientific jargon!) about our recent paper in @AnimalEcology 👇👇. If you want to read the science-y version, see: doi.org/10.1111/1365-2656.14… @AgusBentlage @hannahdugdale @SeychellesWarb

Rainfall is associated with divorce in the socially monogamous Seychelles warbler

To the best of our knowledge, our study is the first to show that extreme rainfall increases the prevalence of divorce in a socially monogamous population. Our findings add to the growing literature...

‘Divorce’ in songbirds: extreme weather pushes couples past breaking point

New research examines the link between extreme weather and divorce in a small monogamous tropical songbird, the Seychelles warbler. Concerningly, extreme rain and dry spells increased divorce rates.

The Czech Turtle Doves tagged this year show two main migratory directions: one via Italy and one via the Balkans. Now they are in Africa where there is no LTE-M network. We hope to hear from them again when they are back in spring! 🕊️ | #HABITRACK #ornithology #birdmigration

Very happy to share our new paper in @PNASNews on how #GriffonVultures change their movement and social behaviour with age: pnas.org/doi/10.1073/pnas.24… It seems that old griffons are much like old humans: they like to stay at home, are set in their routines and are a bit antisocial.
