Argentavis from the Miocene
This article claims that this very large extinct condor
(Argentavis magnificens) had a glide ratio of 3% at 67 kph, which is about 33:1. This is better than many older and some newer (e.g. PW5) gliders. So much for evolution!

Worth a read. (Originally posted on the paraglider SFBAPA Group.) Dave http://www.pnas.org/cgi/reprint/104/30/12398
