Penguin - Super cute flightless bird

Penguins are a group of flightless seabirds that live only in the Southern Hemisphere and have a thick layer of feathers and fat on their bodies to retain heat and keep warm.

When it comes to the cutest birds on the planet, everyone probably thinks of penguins, right? This is a group of birds belonging to the Spheniscidae that cannot fly but in return can swim and dive very well. Besides, they also have a cute appearance with a super adorable waddling gait.

In today's article, let's nicebirds learn in detail about the origin, habits and some of the most popular penguin subspecies today !

Origin and distribution of penguins

Learn about the origins of penguins.

Penguins, also known as winged penguins, are the common name for a group of flightless water birds belonging to the order Sphenisciformes, family Spheniscidae. Currently, penguins only live in the Southern Hemisphere, mainly distributed in coastal areas and islands such as Antarctica, South America, New Zealand, Australia, South Africa,...

The ancestors of penguins appeared about 60 - 70 million years ago, at the end of the Cretaceous period - after the dinosaurs became extinct.

Although penguins belong to the bird class - Ave, they cannot fly at all because their wings have evolved, instead they have the ability to swim and dive superiorly.

General characteristics of penguin body

Penguins are a group of flightless seabirds, known for their unique, cute appearance, thick, insulating feathers, and excellent swimming ability. Let's learn some common morphological characteristics of penguins to understand more about them.

Size & shape :

• Weight: From 1 kg - 40 kg, depending on species
• Height: From 30 - 120 cm
• Slim, diamond-shaped body reduces drag in water when swimming
• When on land, they maintain an upright posture and characteristic waddling gait.

Head & Beak :

• Round head, moderate size
• Straight, sharp, strong beak
• They have no teeth but have many small horny spines in their mouths to help them hold food tightly.

Eyes - ears :

• Large eyes, very good vision, especially when moving in water
• Has ears but no external ear flap, just a small ear hole located behind the eye, hidden under thick fur

Wings :

• Evolved into swimming fins, unable to fly
• Strong muscles, when underwater, act like a real oar
• Wings cannot fold like other common birds

Hair :

• Has a thick, short coat that retains heat well
• Usually the back is dark and the belly is white.
• Every year, penguins will change their feathers periodically once, called "molting".

Skin & fat :

• Underneath the skin is a super thick layer of fat, which retains heat and helps penguins float easily on the water surface.
• For some penguin species living in tropical regions such as the Galápagos, the fat layer will be thinner.

Legs - tail :

• Short legs, slanted backwards, webbed feet
• Waddling gait due to short, inflexible legs
• The tail is short and stiff, helping the bird keep balance.

Penguin Characteristics & Behavior

The penguins gathered in a large flock.

Penguins have many distinct habits and behaviors, demonstrating adaptation to cold habitats and underwater life. Let's learn more about them below.

Live in the herd

Penguins are very social, they always live in large flocks of several dozen to thousands of individuals. Living in large flocks not only helps them keep warm, increase their defense ability and make it easier to find a mate for reproduction.

Excellent swimming & diving ability

Although they are birds, penguins cannot fly, but in return they have excellent swimming and diving abilities. Thanks to the evolutionary process, their wings are used as paddles to help penguins swim at high speeds of 10 - 15 km/h, and some species can even reach 36 km/h. In addition, penguins are also capable of diving very deep from 50 - 500 meters, depending on the species.

Sound recognition

Although living in colonies of thousands of individuals, each penguin has a unique sound. The chicks, fathers and mothers will recognize each other through that characteristic call.

Interesting reproductive behavior

Penguins have many interesting behaviors during reproduction as follows:

• Every breeding season, penguins will return to the exact same nest location thanks to their ability to remember the location for breeding.
• Most of them will mate monogamous and stay together for life.
• Both male and female birds take turns incubating the eggs and caring for the chicks until they are adults.
• In particular, male penguins can fast for several weeks just to incubate their eggs and they will keep warm with a layer of skin on their belly called a "brood pouch".

Common types of penguins

There are currently about 18 different species of penguins, but some of the most popular and well-known species include the “giant” emperor penguin or the majestic king penguin to the cute little blue penguin - each with its own unique features. Find out more below.

A family of king penguins.

King penguins, scientifically known as Aptenodytes patagonicus, are the second largest penguin species in the Spheniscidae family, after the emperor penguin.

Through the above article, nicebirds.net has shared detailed information about penguins - cute little birds with a waddling gait but have excellent swimming ability. Currently, the number of penguins is decreasing due to global warming causing ice to melt at the two poles, leading to the loss of habitat for this bird species. Therefore, let's join hands to protect the environment to protect humans and other creatures.
