Owls do offer excellent rough-field / STOL performance too - not even an F-35 can take off from a glove:

Nature always seems to have us beat

Phys.org)—A small team of researchers with members from France, the U.K., Canada and Germany has discovered that the great frigate bird (Fregata minor) is able to stay aloft for up to two months at a time.

Now this is a interesting precision bombing technique although payload and accuracy are pretty awesome.

Birds gliding through bubbles reveal aerodynamic trick

Gliding birds use tail to generate extra lift and reduce drag.

Not sure I would like an F-35 parked on my hand to try. Similar to the method a bumble bee uses to gain lift from the upswing as well as down.

Now I have seen microphone covers that are broad and very similarly shaped…maybe two mics (asymmetrically seated) in a fuzzy no-foul coating…and these wings?

Feathered robotic wing paves way for flapping drones

Birds fly more efficiently by folding their wings during the upstroke, according to a recent study led by Lund University in Sweden. The results could mean that wing-folding is the next step in increasing the propulsive and aerodynamic efficiency of flapping drones.

Drones, like Starlings…are unpleasant, noisy things.

Softness is what you are after for an owl.

Sorry, Bubo

Bubo

Bubo, in Greek Mythology, was a clockwork replica of Athena's beloved magical owl of the same name. Bubo was forged by Hephaestus and sent by Athena to aid Perseus in his quest to save the princess Andromeda in the original 1981 film. After losing Athena’s helmet in Calibos’ swamp, Zeus orders...

Apologies: My link in #25 has died as institution re-arranged site.
Worse, I've no idea what the linked picture was...

FWIW, some years ago, I was in a craft centre in N.Wales admiring the very, very realistic bird carvings.

Then the biggest, an Eagle Owl, turned on perch and looked me in the eye.

I nearly fell through a display stand...
