Something doesn't appear to be correct with that video demonstration.
Despite the weight of 1 pound and a wing span of 2 meters, the wing
flaps don't appear to be fast enough, nor long enough. How does it
control its turning and other maneuvers?
The different peoples' handling of the bird doesn't appear to be that
which is required for something as large, relative to its little
weight, i.e., very fragile. Another questionable demonstration of
this idea is hinted at, within the 4:15 time of the video, in this
link. In this link, outside, not indoors, a blonde headed girl's hair
(about 2 minutes into the clip) and another girl's purple shirt (near
the end) is blowing in the wind. If the wind is blowing that much, it
would take this very light craft and blow it away, making it unable
for it to control itself against that kind of wind force, in my
opinion. Something just doesn't appear to be correct.
Beyond that, it may not be so important if one makes a flying bird
exactly like a real bird. The different technologies required would
likely lead to other applications that may be more relevant in the
