Thanks for posting the article. Months at a time without landing is amazing.
NICE FIND! Thank you!
“The birds are able to glide so well, the team notes, because they have the least amount of body weight distributed over the total area of their wings of any bird. They also suggested the birds might actually sleep for just minutes at a time as they are carried effortlessly up into clouds.”
