This isn't true: https://en.wikipedia.org/wiki/Hoatzin

... Since Archaeopteryx had three functional claws on each wing, some earlier systematists speculated that the hoatzin was descended from it, because nestling hoatzins have two functional claws on each wing. Modern researchers, however, hypothesize that the young hoatzin's claws are of more recent origin... A similar trait is seen in turacos, whose nestlings use claws on their wings to climb in trees.

TIL :)

People's voice: Shall we leave it up or remove it?

Add a tag of shame to the title.

It is definitely an awesome looking critter though

Thank you! Now I have learned something even MORE interesting, and can still enjoy the cool Hoatzin!

People can still consider an idea even if its wrong.

The text therefore is technically true.

Love the crest. It's so cool that the chicks will have claws that they climb around on trees with!

It can be one step away, if you manage to sneak it into the museum.

What does "ringed" mean in this context?

[–] kootepe@sopuli.xyz 17 points 1 year ago (1 children)

Birds are monitored by putting a ring on their leg. The ring can then be used to identify the bird if it's captured or seen with a telescope/binoculars/camera by someone else, or if their carcass is found. Typically it's just a small metal ring but these days multiple colored rings can also be used, those are put into a public database that anyone can use to identify the bird and see where it has been spotted, when it was ringed, how old it is etc.

Gotcha.

I was familiar with the concept but not the phrasing. Thanks for the edification!

[–] Klear@lemmy.world 9 points 1 year ago

Cause if you wanted to track it then you should have put a ring on it

[–] Bosht@lemmy.world 7 points 1 year ago
