Despite their generally stealthy and solitary nature, these marsupials do produce a range of sounds. While they are not typically known for being highly vocal, certain situations prompt them to communicate through distinct noises. Understanding these vocalizations can offer insights into their behavior and interactions within their environment.
The Range of Possum Sounds
Possums possess a diverse repertoire of vocalizations. One common sound is a sharp, sudden hiss. They also emit a low, guttural growl. These sounds serve as immediate warnings, often escalating if the animal feels increasingly threatened.
Another notable sound is a high-pitched screech or scream. This vocalization is often piercing. Possums can also produce various clicking or chattering noises. These sounds are often rapid and repetitive.
Young possums, known as joeys, have their own distinct vocalizations. They frequently make soft, repetitive “choo choo” sounds or a sound often described as a sneeze.
Reasons Behind Possum Vocalizations
Possum sounds are not random but serve specific purposes, often linked to their survival and social interactions. Hissing and growling are primarily defensive mechanisms. When a possum feels afraid or cornered, these sounds act as a bluff, attempting to deter perceived threats, such as predators or humans.
A loud screech or scream indicates extreme distress or pain. These intense vocalizations are typically made when a possum is under attack, severely injured, or engaged in a physical confrontation with another animal. Such sounds can also signal a fight between competing individuals, particularly during breeding seasons.
Clicking sounds are versatile, used in several contexts. Male possums often produce clicking noises during mating season to attract females, acting as a form of courtship call. Mothers also use clicking to communicate with their young, and these sounds can also be heard when possums are exploring their surroundings or feeling anxious. The soft sneezing or “choo choo” sounds made by joeys are direct calls to their mother, signaling their presence or need for attention.
Identifying Possum Sounds in Your Surroundings
Distinguishing possum sounds from those of other nocturnal wildlife requires attention to their specific characteristics and context. Hearing sounds like hissing, growling, or screeching suggests a possum might feel threatened or be in distress, as they are generally quiet when alone.
If you hear clicking or soft “choo choo” sounds, especially from an attic or under a porch, it could indicate the presence of a mother and her young. These sounds are distinct from the barks or hoots of other common nocturnal animals. Observing the sound’s intensity and frequency, along with any accompanying rustling or thumping noises from movement, can help confirm a possum’s presence. Remember that possums prefer to avoid confrontation, and their sounds are usually a warning rather than a sign of aggression.
