Catalina Island Animal Calls

Raven Animal Calls

On Catalina Island there is a wide variety of animals. Some of the animals that we see include ravens, foxes, bison, sea lions, and whales! Each of these 5 animals make vocalizations, or sounds, for specific reasons.

The common raven typically tends to use one of two calls. The first call is a loud caw or groan. Ravens use this call to communicate with each other. Their call can be heard by ravens that are a mile away! The second call that ravens make is a fast, repetitive caw. Ravens typically use this call when they are hunting prey like rodents, worms, or insects!

The Channel Island fox, Urocyon littoralis, is a relatively quiet animal. However, it can make up to 40 sounds and calls! These calls are used by a foxes to convey different messages to one another. For example, foxes will bark to alert other members of its skulk about danger, such as an approaching predator. The male foxes bark to attract a mate and growl to protect their territory. Female foxes bark to locate their cubs. Sometimes, the small cubs will let out a little  bark just to get mom’s attention!

Bison Animal Calls A bison can often be heard snorting, grunting, and even coughing! Male bison attract a mate by making a deep, low rumbling sound called a bellow. The length, volume, and frequency of the bellow indicates which male is the most dominant and therefore the most likely to find a mate! The female bison uses calls to locate her young. She will produce low grunts and wait for the calf to respond with high-pitched grunts! They repeat this process until they can find each other.

Sea Lion Animal Calls Sea lions communicate both audibly and visually. When they make a sound, they also strike a distinct pose! Male sea lions lift their heads up high in the air and bark when they are claiming their territory. When they are barking to defend their territory from other sea lions, they will bark right in the face of the trespassing seal lion! The female sea lions bark to locate and protect their pups. The female sea lion lets out a loud yell and listens for her pup’s weak crying response!

Whale Animal CallsWhales use clicks, whistles, and calls to communicate with their pod. Toothed whales called odontocetes use echolocation to help them navigate and find food! When echolocating, whales will make a clicking sound and wait for the sound to echo back to them. When the whales hear the echo, they are able to identify the location of the object or animal they are trying to find! Some whales can echolocate prey that is over 1,500 feet away! Whales also whistle and call to socialize with other members of their pod. Scientists discovered that whales have different dialects to help them differentiate between their pod and strangers! Certain low frequency calls can travel more than 10,000 miles across the sea. Pretty wild, right?!
