Finding out why birds are out of range
Sometimes people see large numbers of birds outside of their normal range. A student examined how to predict these excursions.

How birds stay in the air
The sensors inside a boxy device measure the forces generated with each stroke of a bird’s wings. Learning how much force is needed to keep a bird aloft could help in designing future drones that flap, hover and dart.
