For those who might be worried to click: the penguin chicks are fledging and going off to swim for the first time; they are not jumping to their doom.

Its interesting how unskilled nature can be and still get away with it (here I guess to the thick fur/skin/fat below). If humans would jump from such height so badly, many injuries and possibly few deaths would be happening. I've done my fair of jumps in Swiss swimming pools / beaches where 10m jumping board is standard equipment, and even slightly incorrect landing can be quite brutal on the body. Falling ie on the…

It's mainly due to the square/cube law. Small things, including animals, can fall from great heights with little damage.

It's a metaphor.

The innovative use of drones to capture a never-before-seen moment in nature?

Nature/science meets technology/science.

I found this fascinating.

I'd add to the other responses that this footage was the result of technical progress and wouldn't have been possible to achieve otherwise.

Given this video is taken by a drone, and drones are very noisy, are the splashing sounds and sounds of penguins chirping added later?

Perplexity.ai: calculate the terminal velocity of an average sized penguin falling head first -

Sources

omnicalculator.com favicon wikihow.com favicon View 2 more Answer The terminal velocity of an average-sized penguin falling head-first can be calculated as follows: Assuming an average penguin weight of 5 kg and a cross-sectional area of 0.1 m^2, with a drag coefficient of 0.8 for a streamlined, head-first orientation: Terminal velocity, v_t = √((2 × m × g) / (ρ × A × C_d)) Where:

    m = mass of penguin = 5 kg
    g = acceleration due to gravity = 9.8 m/s^2
    ρ = density of air = 1.225 kg/m^3
    A = cross-sectional area = 0.1 m^2
    C_d = drag coefficient = 0.8

Plugging in the values: v_t = √((2 × 5 kg × 9.8 m/s^2) / (1.225 kg/m^3 × 0.1 m^2 × 0.8)) v_t = √(98 / 0.98) v_t = √100 v_t = 10 m/s Therefore, the terminal velocity of an average-sized penguin falling head-first is approximately 10 m/s or 36 km/h.1345
