This seems like the best place to post this. Does any one know what bird has the largest wing-span? and what is it?

The wandering albatross (Diomedea exulans) has the largest wingspan of any living bird. As a result, it is an expert glider and it is capable of remaining in the air without beating its wings for several hours at a time. The largest known specimen was an extremely old male with and 11 ft. 11 in. wingspan. It was caught in the Tasman Sea in September 1965. It has also been known to sleep while it flies!

Thanks, Jenny

How could it sleep while it was flying?

No idea Kalena
Got the info from my bird book!
