For my first post here, I’m happy to share our new paper just published in @ibisjournal.bsky.social Thanks to a great team effort, we made a small step forward in the study of Siberian vagrants in Europe and clarified the status of two (pseudo) vagrants: the YBW & the Sib Chiffchaff. Some results 🧵

GREAT NEWS in #conservation: the government of New Zealand has announced that they will include feral cats in their PredatorFree 2050 strategy, aiming to benefit #seabirds and landbirds across NZ by removing feral cats:
Feral cats to be added to Predator Free 2050
The Government is delivering on its campaign promise to add feral cats to the Predator Free 2050 target species list to protect our precious native wildlife, Conservation Minister Tama Potaka says.

Even consummate migrants like Corncrakes can end up being ship-assisted, although presumably being adopted by a family and fed prawns is a rarer occurrence.... #UKBirding #Ornithology

Just out in Systematic Biology, we explore the role of gene flow in island phylogeography of the Solomons Black-and-white Monarch complex. doi.org/10.1093/sysb...

Up first, strong genetic structure between islands groups and weak (but present!) structure between Pleistocene-connected islands (🧵)
Figure with a photo of a member of then Solomons Monarch complex, a map of the Solomon Islands (divided into four island groups, Makira being the most isolated), and a principal component analysis highlighting the distinct between-island-group structure, with moderate structure within the New Georgia Group and weaker structure within the Bukida group (highlighted in an inset).

Earlier today, I was notified that someone was at my door.

This is who it was:
A male Anna’s hummingbird at the door. So nosy! 🤣

We visited plaine de Crau (S France) to catch Richard’s pipits last week and sample feathers for isotope tests. Numbers were low (~10), though more birds usually stop here at this time of year (up to 30/40) before they move south. Unclear if birds left early or had a poor breeding year.. #birds

On the train back home, still buzzing from some great days at @vogelwarte.bsky.social where Hans Schmid wrote "Getrennte Wege" - a classic synthesis of Honey Buzzard migration. A quarter century later the species has revealed a few more, but still not all of its migratory "Geheimnisse". #ornithology

This Swallow at Balranald, N Uist this afternoon appears to be the American subspecies: erythrogaster due to the lack of a dark band across the lower throat.

This is such a cool study. A parasitic ant queen tricks worker ants into murdering their own queen, so the parasite can take over the colony.
This parasitic ant tricks workers into committing matricide
Newly mated parasitic queen ants invade colonies and spray their victims with a chemical irritant that provokes the workers to kill their mother.

Going to be a big month for warbler science! First out of the gates is @lannhiphung.bsky.social, with song & genomics of Nashville warblers. Eastern and western subspecies: non-overlapping and super distinct. Keep an eye on your life list 😉

Our new @science.org paper is out! Cuckoos and hosts are locked in a coevolutionary arms race over egg mimicry.

But how are these egg types inherited, and could this drive speciation? We sequenced hundreds of genomes to find out!

Genomic architecture of egg mimicry and its consequences for speciation in parasitic cuckoos
Host-parasite arms races facilitate rapid evolution and can fuel speciation. Cuculus cuckoos are deceptive egg mimics that exhibit a broad diversity of counterfeit egg phenotypes, representing host-ad...

Why are Procellariiform seabirds most diverse in the Southern Hemisphere?

Our study found that wind patterns and time since evolutionary origin best explain the extratropical peak in breeding species richness of these remarkable seabirds. 🐦💨

A short stay on Corvo finally turned into a long one due to a plane issue for almost a week.. While extra days were slow, first days were exciting: best was finding the 2nd Ruby-crowned Kinglet (8th WP), plus some nice extra species (Cape May, Protho & Magnolia Warblers) 🪶
