super cool study found human artifacts in Bearded vulture nests, incl. "weaponry like a crossbow bolt and wooden lance, decorated sheep leather, and parts of a slingshot....a shoe made from twigs and grass is ~675-years-old." link to paper: doi.org/10.1002/ecy..... www.popsci.com/environment/... 🧪🌍🦉

NEW PAPER: Red-breasted mergansers do not move parasitic eggs to cooler nest edges, suggesting limited use of discriminatory incubation against conspecific brood parasitism, though some eggs may be selectively removed.

:-) it didn’t nap - they are quite heavy birds so when put in the hand, they stay on their back/wings for some time. It may also be a strategy called tonic immobility (similar to tanatosis) that helps them avoid predation attack.

Our fieldwork on brood parasitism of common cuckoos started well, with so far 11 caught individuals! When catching these charismatic birds, there are usually also interesting bycatches :) @ivb-cas.bsky.social @rytikerttunen.bsky.social @lisandrinamari.bsky.social

It’s all about eggs at BTO right now, but not the chocolate kind! 🐣 We’re busy during the nest monitoring season! 🐦 You can get involved too by watching birds in your garden and submitting records to our Nesting Neighbours scheme. 👉 www.bto.org/nest-mon...
So whose eggs are these? ⬇️ #Birds
Map of the world showing the locations of six BTO tagged Cuckoos, with five in Spain and one (Sayaan) in Italy. Six headshots of Cuckoos with their names accompany the map. The Cuckoos featured are: Cleeve, Joe, Hafren, Sayaan, Wilfrid and Cuach Cores. Accompanying wording reads: Update 16th April. Six Cuckoos in Europe! BTO Cuckoo Tracking. BTO logo sits top right of the image.
The race is on! 📢 Six BTO Cuckoos have touched down in Europe! 🌍 So where are our frontrunners and who will be the first to reach the UK? 👇 www.bto.org/cuckoos #Ornithology #Birds
