Hi everyone, happy to share with all of you the paper from the second chapter of my PhD, where we show that more exploratory birds use a broader foraging niche, linking consistent behavior with ecological flexibility. I hope you can enjoy it and share it!!!

Exploration Behavior Is Consistent and Associated With Foraging Behavior in Island Songbirds
We tested the neophobia threshold hypothesis in six landbird species, including four Darwin's finches. Exploration behavior was consistent over time and contexts, with species exhibiting greater fora....
