What is Rhynchokinesis?

[@Trickyboy1337]

I just found this channel a few hours ago, and have been eagerly devouring the information it offers. You're seemingly very passionate about this topic and pursue it at least as much for yourself as for yout viewers, if not more so. Still, I wanted to thank you for sharing this knowledge of avian taxonomy, physiology, habitat, and behavior! Ecology is a relatively new fascination of mine. It isn't exactly a common layman curiosity, so finding easily accessible and easily digestible presentations on it are rare. Again, thank you!

Thank you, very much appreciated! And welcome!

This is so fascinating! I love how you break down the anatomy and physiology of how the intricate muscles and bones work in the top beak. It makes me wish I'd followed my original dream of becoming an Ornithologist and Avian Veterinarian! Just a thought: Don't let anyone (even Vets) discourage you from following your dreams and passions - the world needs more people dedicated to understanding and caring for birds!

Muscles? Where?

[@ChrisNP87]

@@footfault1941 well how else can they control the movement? It has to have some muscles attached to cause movement.

@@ChrisNP87 here're for your quick glance, as I did. Estrella & Masero 2007 J. Exp. Biol, & Gussekloo et al. 2001 j. Exp. Biol. Not specifically described mechanisms we're interested in, but referable for kinematics.

[@ChrisNP87]

@@footfault1941 while they may not have been looking into the physiological mechanisms in that specific older research, because it was focused on efficiency and use, I'd believe there are fenestrations with which muscles reside and assist in the movement of the beak. That's my hypothesis, at least. 😀

i remember seeing images of birds where their upper and lower bills didn’t seem to align, but i never knew why. nice to finally have an answer

[@gordianplot9347]

I had noticed this in a rescued raven. it was most noticeable when he was stretching or playing with toys. thank you for the explanation of this strange counterintuitive movement.

[@dianestiner8602]

I am fascinated with ALL I discover in birds with you 😊. Thank you 🧡

[@allthingsbirdie]

My pleasure!

[@fluffykins1139]

Great concise explanation on a topic I've never heard of! Nice job with the editing too. Thank you!

[@allthingsbirdie]

Glad you enjoyed it!

[@allyf.8370]

I'm so glad I found this channel. Such niche content, and I am the exact target audience.

[@allthingsbirdie]

That's wonderful to hear, and welcome!

[@nataliab.a.1558]

What a perception! Fascinating. Thanks for the explanation.

[@lorirober2536]

Amazing! I never even knew about this! Thank you for this excellent explanation.

[@rileyrobin2]

the perfect amount of slide whistle.

[@adialamdigital]

Clean image, thanks for sharing

[@petralawson2044]

I'd never noticed this either! Thanks for another wonderful and informative video 0u0

[@EyeSeeThruYou]

I love it, thank you for this educational content!! I live with pstticines and would never witness this bill flexibility, so the explanation of why shorebirds and hummingbirds do was excellent! 👍

[@jeffolson4731]

I have not noticed this. I will definitely pay more attention from now on both while in the field and while looking at my pictures.

[@M.nivalis]

As a terminally online outdoorsy doofus, how is it that I’m just now discovering this channel? The Algorithm done did me dirty by delaying this long, this is my kinda content.

[@M.nivalis]

Hold up you’ve been active for TWO YEARS?!? Buckle in, it’s time to frolic through the archives

[@footfault1941]

Honestly, skeptical. Yes, birds' skull is structured more flexible compared, for instance, ours. I thought rhyncokinesis takes place in the skull (joint between bones), not in the beak. A difficult part is in mechanisms at work. No muscle or tendon is supposed to be involved. The phenomenon waits further investigation. PS. Apologies for my misunderstanding above. At a quick glance, it became clear there have already been researches reported in scientific magazines (e.g., Estrella & Masero 2007). It's an interesting phenomenon, but detailed descriptions on the mechanism seems yet to be available (although Gussekloo et al. 2001 refers to kinematics of pieces of bones involved in that action). Eco-evo significance of this unique movement yet waits further investigations.
