Hummingbirds
D
Correct answer
Explanation
Hummingbirds are unique in their ability to fly backwards, and they're the only birds that can sustain backward flight. Their specialized wing structure allows them to hover and fly in any direction - forwards, backwards, sideways, even upside down. House flies can hover and move in various directions but don't truly 'fly backwards' in sustained flight. Ostriches cannot fly at all, and eagles cannot fly backwards.
