How would you?

Question

How would you design an experiment to establish if owls hunt by keen sight or hunt by heat seeking.

Answer 1

Place several owls and a few mice in a room heated up high enough to camofluage the mice's body heat.

Or, place them in a room with absalutely no light. Not, just at night time, when there's the stars and the moon giving light, but in a room with NO light.

Answer 2

Put an owl and a mouse in a large completely sealed dark room with no light at all. See what happens.

Answer 3

Give them glasses with tape on the lenses so they can't see, tape the glasses to their head. Then put a mouse somewhere in the room and see if they can get it and eat it.
