An ornithopter Credit: Institute for Aerospace Studies
No jet engine, no propeller. This ornithopter, designed by James DeLaurier and researchers at the University of Toronto's Institute for Aerospace Studies, is designed to fly by flapping its wings.

Esta muy bien...
Pero vuela o no esa huevada?

No es un nido
Creo que intenta ser un pájaro no un nido, digo: lo de huevada sobra.
Gracias por hacernos quedar tan bien (sic) a los hispano parlantes.

The Problem remains the same...
What happens when a flapping object flaps? The center
moves up and down in response to the wings moving in the
opposite direction. Try to land and the center section keeps
slapping up and down against the runway as it comes in,
making for a very, very rough landing by comparison to a
powered glide path. Hmmm... This falls into the same
realm as the concept of airship cranes -- nice in concept,
but impractical in implimentation for reasons based on
simple physics.

Ever watched a bird landing ?
When you ever watched closely how a bird lands,
you will have noticed that the bird keeps his
wings steady under a particular angle with the
ground.
This air plane can do exactly that.
Meaning, it can have a smooth landing on a much
smaller area than with a propeller driven air
plain.

can stop flapping a few feets ahead of landing.
The wing can stop flapping at least 40 feets from landing ground. The lift or drag that creates the pressure, and generated due to the flapping action, is sifficient enough even if the aircraft stops flapping ( about 30 - 40 feets from ground), or loss at a rate sufficiently slow enough to provide the smooth landing.
Take the example of a simple flying bird. If one has notice, the bird stops flapping a few distance away before it land on ground. although, the flexibility of the birds wing should be u in consideration but still the aerodynamic wings can be design in such a way to achieve this.

Although, the flexibility of the birds wing should be in consideration but still the aerodynamic wings can be design in such a way to achieve this.For example the wings can be divided in two portions, Front and Rear and during flapping the angle orientation of the wing should be 0 degree and as the wings stop flapping, the rear wing should be tilted at some orientation with respect to the co-ordinate axes, to make up for the Lift loss due to the flapping action.

Canadian Dinosaur re-invents mechanical bird
Yup,

From the people who brought Canadians nothing but paying their salaries, we now have ...

THE MECHANICAL BIRD ... lol

University of Toronto is, I believe, just about the stupidest place on earth.
