![]() ![]() ![]() Our findings show that penguins may use vocal communication in the ocean related with group association during foraging trips. Penguins undertook dives of shallower depths and shorter durations after producing an offshore call than those before producing an offshore call. Group associations were observed within one minute following an offshore call in almost half of the instances (43.18%). The offshore calls varied in their dominant frequency and length, and penguins produced calls of different lengths in succession. From the video recordings, we collected 598 offshore calls from 10 individuals in two breeding seasons (2014–20–2016), and we analysed the acoustic characteristics and behavioural contexts of these calls, including diving patterns, group association events, and foraging behaviour. We deployed an animal-borne camera on gentoo penguins ( Pygoscelis papua) and recorded their foraging behaviour during chick guarding. Here, we present the first description of the vocal behaviour of penguins in the open ocean and discuss the function of their vocal communication. This streamlined design helps penguins swim fast.In contrast to their terrestrial call, the offshore call of penguins during their foraging trips has been poorly studied due to the inaccessibility of the foraging site-the open ocean-to researchers. According to some animal experts, the penguin is one of the most streamlined animals in the world.Ī penguin’s body is tapered at both ends and it has a large head, short neck and elongated body. The ladies use these rocks to build a nest. Many male penguins gift female penguins with rocks in order to woo them. They use their feet like rudders, angling them to help control direction. Penguin feet are also adapted to help the birds steer while swimming. ![]() Some species of penguins can march up to about 60 miles across sea ice to get to their breeding grounds. That’s because penguins live south of the equator while polar bears north of the equator in Arctic! Penguin feet are adapted to walk long distances. Contrary to many popular holiday cartoons, you’ll never see penguins and polar bears together in the wild. You can find them in Antarctica and Antarctic islands, the Galapagos Islands off the coast of Ecuador, South Africa, New Zealand, Australia, Peru and Chile. Penguins live in many locations and habitats. Penguins spend several hours each day covering their feathers with this oil and give extra attention to the task before swimming. A penguin’s thick feathers aren’t the only way this bird stays warm.Ī gland near the base of its tail provides waterproof oil. This helps them swim because solid bones reduce buoyancy-the tendency to float. Penguins adapted with solid bones instead. Most birds have hollow, air-filled bones to help them stay light for flight. In frigid habitats, huddling helps penguins retain warmth. This behavior helps these birds protect themselves from predators. Penguins may huddle together for several reasons. Their white bellies help them blend in with the bright surface of the ocean when viewed by predators and prey from below. When swimming, the black on their backs helps them blend in with the darkness of the ocean from predators viewing from above. The black and white “tuxedo” look donned by most penguin species is a clever camouflage called countershading. Other names for a group of penguins include rookery, colony, and huddle. A group of penguins in the water is called a raft but on land they’re called a waddle! ![]()
