Uralte Papageienfedern geben Handelsrouten aus der Vor-Inka-Zeit preis Papageienfedern begeisterten schon in der Vor-Inka-Zeit. Forscher konnten anhand von uralten Grabbeigaben einem Papageienhandel auf die Spur kommen.

Live parrots were carried across the Andes before the Incas’ rise Ancient DNA and other clues from feathers found in modern Peru hint that the ancient Ychsma culture imported birds from the distant Amazon.

Ancient DNA reveals a pre-Inca trade of live parrots YouTube video by Wildlife Messengers

Parrots, ancient DNA, and a long trek across the Andes! 🦜🧬🏔️ Check out the video summary for our latest @natcomms.nature.com paper by @wildlifemessengers.org. We discovered pre-Inca societies transported live Amazonian parrots from the rainforest to the Pacific coast: youtu.be/Vb5eoTaGLO0

Huge thanks to Prof. Izumi Shimada and my amazing co-authors for this incredible cross-disciplinary journey fusing #ecology, #genomics, and #archaeology.

Isotopes showed the birds survived the trade and lived on the coast, eating a diet of maize (possibly fertilised by seabird guano). 🌽🌊 This proves pre-Inca regional states managed vast, complex trade networks centuries before the Inca Empire.

🧬 Using ancient DNA and stable isotopes from 600–1,000-year-old feathers found at Pachacamac, Peru, we found these birds were possibly wild-caught in the rainforest and carried over 500 km across 3,000-metre mountain passes. 🏔️ A great logistical feat in pre-Inca cultures!

Ancient DNA and spatial modeling reveal a pre-Inca trans-Andean parrot trade - Nature Communications Here, the authors combine ancient DNA, stable isotopes, and computational modeling to study colorful feathers from a pre-Incan tomb in Peru. They identify four species of parrots, which were likely ca...

🦜🏔️ How did vibrant Amazonian parrot feathers end up in a desert tomb on the Pacific coast of Peru 1,000 years ago? Our new paper on @natcomms.nature.com reveals they didn't just trade feathers, pre-Inca societies transported live macaws and parrots across the Andes!👇 www.nature.com/articles/s41...

VERY EXCITED to see a special little spider I discovered in Peru make it to the big screen. Check out The Secret Lives of Animals episode 3 on Apple TV.

Cyclosa Menge, 1866 (Araneidae) Orb‐Weavers Build Stabilimenta That Resemble Larger Spiders The orb-weaving spider Cyclosa longicauda from Peru constructs unique stabilimenta from detritus and silk that visually resemble a larger spider. This previously undescribed behavior likely functions....

In our new paper with @philtorres.bsky.social @aaronpomerantz.bsky.social et al. published in @ecol-evol.bsky.social we describe the mystery of an orb-weaving spider (Cyclosa sp.) 🕷️ and why they possibly construct larger "spider-shaped decoy" in their webs. onlinelibrary.wiley.com/doi/10.1002/...
