Nature&rsquo;s creations not only have distinct features but also spectacular colours. An example of this is the Anna&rsquo;s hummingbirds which are known for their striking hues. What makes them magnificent to observe is the change in their colours when seen from varied angles as shown in a video posted on Twitter by Wonder of Science.</p>

The thumb-sized bird displays shades of fluorescent reddish-pink and black as it changes the angle.</p>

Hummingbirds according to Science Daily have the brightest colours in the world. The shade change occurs as their feathers reflect light in a way that the birds can match. The pancake-shaped structures in their feathers result in reflection of rainbow colours when they turn their head.</p>

Viewers were captivated with the footage. One remarked: &ldquo;Ok, this beautiful thing made my day,&rdquo; while another said the bird looked like an &ldquo;upgraded version of chameleon.&rdquo;</p>
