"bird 6" is a model of Quetzalcoalus:

http://en.wikipedia.org/wiki/Quetzalcoatlus

a pterodactyloid (flying reptile, no related to dinosaurs) from late Cretacious period (84 to 65 million years ago). It was built for a Science TV documentary.

(I also love Evolution's secretprojects ;D)

The third pic reminds me of something called 'Winggrid', website is gone now but was a concept involving 'feather-like' winglets.

Really great, probably the most agile lighter-than-air vehicle ever built.
But heavier-than-air, man carrying ornithopters still seem notto be
around the corner.
But, would there be any advantage to other concepts ?   ???

Re: the flying scale-model of 'Quetzalcoatlus Northropi', there's the following paper: A. N. Brooks, P. B. MacCready (et al), 'Development of a Wing-Flapping Flying Replica of the Largest Pterosaur', AIAA Paper 85 - 1446, 1985.
(And yes, I gather the beast is officially Q. 'Northropi' because of its resemblance to one of Jack N.'s fabulous flying-wings.)

What about the Bich-16 and Bich-18?  :D

I head that the Quetz was a real pain to keep from blowing off the vehicle while it was being taken uprange (people had to ride on the outside of the truck to keep it on...

Although it does fly, and surprisingly well, but I wouldn't quite call it an "ornithopter" because this means "bird's wings", and obviously this one ought to be called "whale's flaps"...

To be still the most precise, the ray is a fish. Then we have a fish wing and going to a classical greek derivative it would be called "ichthyopter"

Thanks! You are absolutely right, it is not in the shape of a sea mammal but a fish, indeed.

To be quite accurate, it should be spelled "ichtyopter". Thanks again!

An attempt from 1937, the Riout 102T "Alérion", not succesful, but still existing
today at the musée régional de l'air d'Angers:
