SSC Selection Post 2020 PYQ — Question 27

The correct answer is Option 4 i.e. Hummingbirds

Hummingbirds are the only birds that can truly fly backwards. This unique ability is due to their specialized wing structure and musculature. Unlike most birds that generate lift primarily on the downstroke, hummingbirds can rotate their wings 180 degrees at the shoulder joint, allowing them to produce lift on both the forward and backward strokes. Their rapid wing beats, which can exceed 50 per second, create a figure-eight pattern, enabling them to hover, fly sideways, and even fly upside down, in addition to moving backward.
