BIRDS

Vulturine guineafowl

Vulturine guineafowl move in highly cohesive groups. This cohesion allows them to coordinate their actions as they move together through the landscape, and therefore maintain stable group membership over extensive periods of time. James Klarevas, Max-Planck-Gesellschaft.

 

Some Smart Dino-Birds...

Complex Society Discovered in Birds,
Max-Planck-Gesellschaft, November 4, 2019

MAIN POINTS

"Multilevel societies have, until now, only been known to exist among large-brained mammals including humans, other primates, elephants, giraffes, and dolphins."

The Vulturine guineafowl
"...the birds can keep track of social associations with hundreds of other individuals--challenging the notion that large brains are a requirement for complex societies and providing a clue as to how these societies evolved."

Complex Dino-Birds
"...the researchers observed these birds, that are from an ancient lineage resembling dinosaurs more than birds, behaving highly cohesively without exhibiting the signature intergroup aggression that is common in other group-living birds."

Complex Society
"...the position of every single group was recorded continuously each day, which allowed researchers to simultaneously observe how all 18 groups in the population were interacting. The researchers found that groups associated with each other based on preference, rather than random encounters, and also showed that intergroup associations were more likely to take place during specific seasons and around particular physical features in the landscape."

"It is remarkable to observe hundreds of birds coming out of a roost and splitting up perfectly into completely stable groups every single day. How do they do that? It's obviously not just about being smart."

New Social Mechanism-Model?
"...opened up exciting possibilities of exploring what is it about this bird that has made them evolve a social system that is in many ways more comparable to a primate than to other birds."

"Many examples of multilevel societies -- primates, elephants and giraffes -- might have evolved under similar ecological conditions as vulturine guineafowl."

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

I NEED HELP!
If you feel these efforts are valuable, I'm cordially inviting you to support them, here:

 

 

I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
