Some current thinking is that birds are the living surviving dinosaurs -- they mostly walk on two legs and have other anatomy and physiology in common, or that is the case for them. I had some close observation of albatross (Laysan) on Midway Island, was able to observe the whole process from egg to learning to fly, pairs doing the mating dance ritual, which is also socializing, with three or more birds. They do skid when landing on ground instead of water, and were then dubbed Gooney Birds, but they are the masters of air and sea, and have a wingspan of about six feet. Their nesting areas covered the Navy base, but much more ground too. That island is now completely a wildlife refuge. There may be researchers out there, but I'm not sure there is any permanent party at all, no military, and the attempt at tourism faded, I believe. It's as far from Honolulu as it is from New York to Omaha. It's part of the Hawaiian chain, but truly remote. There've been some serious loss of birds from eating plastic trash they mistake for sea life like squid. I've seen photos of albatross chick and adult remains with the bones arranged around a little pile of plastic trash that plugged their digestive tract.
