Sunbirds don’t drink nectar like hummingbirds. They use intralingual suction: the tongue acts like a straw, moving nectar via pressure differences rather than capillarity. A clear case of biomechanical divergence despite ecological convergence.

Tiny hands, tiny birds, big curiosity. 🐦⬛✨ We took local grammar school kids bird ringing—and they loved it. From gently holding a warbler to learning why birds wear “bracelets,” they got a front-row seat to real science. 🔍📏💍 = ❤️ 🔗

Paper is finally up and open access (
www.journals.uchicago.edu/doi/10.1086/...
), it's a sequel to an earlier paper where we'd argued that there's not good evidence that pre-publication peer review is a net benefit (
www.journals.uchicago.edu/doi/10.1093/...
). So in this one we suggest an alternative.

Unsolicited listicle: My list of the most criminally underused/underappreciated phylogenetic comparative methods. Note, I am not involved in ANY of these methods; but I see them as things people are often asking of comparative data but have been surprised at how infrequently they have been cited.
