How an Airplane-Sized Bird Replaced Its Feathers

Bird size is limited by the time it takes to replace feathers. An extinct bird the size of a Cessna airplane and weighing as much as an average human was one of the largest birds to have ever flown the friendly skies.
Scientists have wondered how the bird, called Argentavis magnificens, could balloon to such heft (more than 150 pounds, or 70 kg) and still replace its feathers during a molt. Now, new research reveals the bird, which lived 6 million years ago in the Miocene epoch, likely molted all of its feathers at once during a long fast.

They say that a California condor in distant flight can be mistaken for a small aircraft.
But this giant crow takes the cake!

A very large male condor was cruising beside the road the other day as I was going to the city. We see them all the time. They are everywhere but this guy was HUGE. I can guess the wingspan was well over 12 or 13 feet!

If you don’t mind my asking, where do you see them all the time? South Rim? Kolob Canyon? Pinnacles NP? Big Sur?

Thanks JoeProBono. An extinct bird the size of a Cessna airplane and weighing as much as an average human was one of the largest birds to have ever flown the friendly skies. Scientists have wondered how the bird, called Argentavis magnificens, could balloon to such heft (more than 150 pounds, or 70 kg) and still replace its feathers during a molt. Now, new research reveals the bird, which lived 6 million years ago in the Miocene epoch, likely molted all of its feathers at once during a long fast. Lions don't molt! No, but penguins do! There! I run rings around you logically!

It was lucky of them to stumble across a flock of these birds to research, so they could watch them all fast and molt.
