Raccoons are nocturnal animals often found near human environments. They are quite vocal, using a diverse array of sounds to communicate. Understanding these vocalizations provides insight into their behavior and the situations in which they are typically heard.
The Raccoon Sound Repertoire
Raccoons possess an extensive vocal repertoire, producing over 200 distinct sounds. Their vocalizations range from clear, tonal notes to rougher calls. They can emit a high-pitched whistle, a musical sound that can carry over 300 feet. This whistling can be particularly noticeable in young and adult raccoons.
Chittering consists of short, high-pitched noises that combine purring and clicking elements. Raccoons also produce a distinct purring sound, often described as similar to a kitten’s purr, which can be rhythmic and pulsating.
When agitated or threatened, raccoons may growl, a low, guttural vocalization that can include snarls. This sound resembles a dog’s growl. Hissing is a defensive sound, similar to a snake’s hiss. Raccoons also bark, a sound comparable to a dog’s bark.
Screaming or screeching are loud, high-pitched sounds raccoons make, sometimes described as owl-like cries. Additionally, raccoons may make grunting noises. Baby raccoons often produce high-pitched squeals, cries, and mewing sounds.
Interpreting Raccoon Calls
The specific sounds raccoons make often directly correspond to their emotional state or the situation they are experiencing. A high-pitched whistle can serve as an alarm or it can be a way for a mother raccoon to locate her young. Whistling can also indicate contentment, fear, or excitement.
Chittering sounds are associated with playfulness, curiosity, or greeting other raccoons. Mother raccoons use chittering to calm their young, and adult raccoons may chitter to self-soothe when stressed. This vocalization can also announce the presence of food or water.
Purring typically indicates contentment and satisfaction, often heard from young raccoons being groomed by their mothers or from adults when they are relaxed or eating.
Growling usually signals aggression or a defensive posture, particularly when a raccoon feels threatened or is defending its territory. This sound warns others to keep their distance and can escalate if the threat persists. Hissing also communicates fear, threat, or aggression, serving as a warning to back off. It is a common sound during territorial disputes or when a mother protects her offspring.
Barking can convey excitement, such as finding food, or stress and agitation. Female raccoons may bark during breeding, and mothers use it to call their lost young.
Screaming or screeching vocalizations are often heard during distress, pain, fights, or mating. These loud cries can startle predators or signal aggression between competing males. Young raccoons often squeal or cry when in pain, fear, or seeking their mother’s attention, especially when hungry. Grunts can be a casual greeting or indicate submission, fear, or aggression.
Identifying Raccoon Sounds
Distinguishing raccoon sounds from those of other nocturnal animals often involves considering the sound’s characteristics, the timing, and the surrounding environment. Raccoons are most active at night, so noises heard between late evening and early morning are often attributed to them. Their larger size means their movements tend to produce heavier thumping or rustling sounds, especially if they are in an attic, walls, or chimney. This contrasts with the lighter, quicker scurrying sounds typically made by smaller animals like squirrels, which are mostly diurnal.
Raccoon vocalizations themselves have unique qualities. Their whistles can sometimes be mistaken for an owl’s call, making context important for identification. The combination of purring with clicking in chittering is a specific raccoon trait.
While other animals like foxes and opossums also vocalize at night, raccoon screams, particularly the loud, high-pitched ones, are often distinct and can sound eerily like human baby cries. Growls and hisses from raccoons are typically deep and guttural, used as clear warnings. If these aggressive sounds are accompanied by visual cues like an arched back or raised fur, it further indicates a raccoon.
Observing the location of the sounds can also provide clues. Raccoons are known for rummaging through trash cans or seeking entry into attics and other structures, so noises originating from these areas are often indicative of their presence. The pattern of vocalizations, such as a series of barks followed by screams, can also point to raccoons engaging in territorial disputes or mating behaviors. Paying attention to these combined elements helps in accurately identifying the source of nocturnal sounds.
