Great to work with you and your team, Marisa!

Thanks for sharing, Roli. And big thank you to you and your team at PLOS Biology for an efficient and constructive peer review and publication process, and for helping to support (our) big team science efforts.

Always a pleasure working with you, Vedrana! Thanks for all that you do :)

It was such an incredible, enriching, and fun experience — I learned so much ❤️ So thankful to the amazing leadership team who welcomed me! @drrmiller.bsky.social @vedranaslipogor.bsky.social @nomascus.bsky.social @stephanreber.bsky.social @cds-york.bsky.social Megan Lambert & Claudia Mettke-Hofmann

Great to work with you, Vanessa and Basel Zoo!

Thank you so much!

Great to work with you, Christine!

Such a pleasure to work with you, Ondrej!

Hello, thank you - you can find all species listed in our supplementary information (data files and site information)

Big thank you to our ManyBirds core leadership team: @drrmiller.bsky.social, Megan Lambert, @vedranaslipogor.bsky.social, @nomascus.bsky.social, @jimeloism.bsky.social, Carl Soulsbury, @stephanreber.bsky.social, Claudia Mettke-Hofmann - and to all of our collaborators!

The #ManyBirds Project shows how big team open science approaches can uncover hidden patterns in animal behaviour and evolution, complementing critical in-depth single-lab work.
Huge thanks to everyone involved across six continents 🌍💛 More info & how to join future studies: 👉 www.themanybirds.com

Birds tested in groups were more neophobic than those tested alone - likely waiting for others to take the risk first!
And individuals showed consistent behaviour over time, suggesting neophobia is a stable behavioural trait.

Two main ecological factors predicted neophobia:
🥗 Dietary specialisation – species with narrower diets were more fearful.
🧭 Migratory behaviour – migratory species were more cautious.
➡️ Supporting both the Neophobia Threshold & Dangerous Niche Hypotheses.

Across 1,439 birds from 136 species and 25 avian orders, we used standardised tests:
familiar food was presented with and without a novel object.
⏱️ Longer hesitation = higher neophobia.
Flamingos were cautious, falcons bold - big differences across species!

Neophobia - the fear of novelty - shapes how animals balance risk and opportunity.
Too much caution can limit flexibility, but too little can be dangerous.
We asked: why do some bird species fear new things more than others? 🐧🦅
