Well, I have never seen a real bird fly like that TED bird (so slow). Granted it is gracious and beautiful and looks real nice indoor, but to me it doesn't resemble the flying of a real bird. Also the wingflap is not realistic. Real birds don't flap the outside part of the wing down further then the inside part, but it makes a kind of rowing action. The TED bird flies like a bird in a cartoon or documentary (where footage is slowed down to make it look nicer).
Furthermore the dutch DIY guy was 2 years earlier, without a reseach team and substantial budget.
If someone were to offer me the choise between the two, I'd take the dutch diy bird, but everyone is entitled to his own opinion :-)
The bird in the TED video is amazing. I saw a documentary on the making of that bird. At the end, they take it to the beach and fly it with real seagulls. The real seagulls didn't seem to know that it wasn't a real bird. They all mingled in the air together.
@u4eake - there is a huge difference between the Netherlands one and the TED one. The one you showed is an insect-like flapping wing. The TED one is very amazing. The bird wing is creating both lift and thrust. The inner wing is generating lift, and the outer wing is generating thrust. I haven't seen one before this TED video. Simply amazing.
Refer to a book called Fixed and Flapping Wing Aerodynamics... You'll see how different they are.

So apparently the DIY market are ahead in design just not grace. Frankly the fact that our manufacturing has reached this has amazed me but having it fly with such grace (unlike the DIY version) is just dumbfounding. 450g is my LiPo and APM :S not sure an autonomous DIY one will happen quite yet :D
DARPA funded hummingbird shows even more is possible
This bird is DIY made by a guy from the Netherlands. I saw it fly on my first fpv meeting, 2 years ago and I was duly impressed ! Only close by it could be distinguished from a real bird. Can you see which one is the real one ?
I have seen somewhere a DIY version, but not this big. this is huge 2 meter span=7 ft?, and the AUW only 450 grams (1 lbs). Put APM on it it flies forever

He also has a bald eagle :
Hi,
they really got the hit with this bird... too sad its most likely to stay an adverisement tool :-(
@Ben: with a weight of 450g, thats over 30W/kg. There are planes flying at 10 or under.
@inout: It´s manual flight in this show, see the person with the radio next to the throw.
Impressive.And it seems it has a good autopilot
