Introduction
Unlike social animals that rely heavily on vocal interactions, opossums have a more limited sound repertoire. Despite this, they make various distinct noises, especially when threatened, communicating with their young, or during mating. Understanding these sounds can help you appreciate these nocturnal visitors and better interpret their behaviors.

Types of Opossum Sounds and Their Meanings
1. Hissing
- Characteristics: High-pitched, sharp sound.
- Purpose: Defensive mechanism to ward off threats.
- Context: Opossums typically hiss when they are cornered or feel endangered, showing their teeth as an additional warning. This sound is a clear sign that the animal feels threatened but is not necessarily preparing to attack.
2. Growling
- Characteristics: Low, deep, guttural sound.
- Purpose: A more serious display of aggression or stress.
- Context: Opossums growl when they are highly agitated, often during territorial disputes or when confronted by predators. Growling indicates that the opossum is highly stressed and may escalate its defense if necessary.
3. Clicking or Smacking Sounds
- Characteristics: Soft, rhythmic, and repetitive.
- Purpose: Maternal communication between a mother and her young.
- Context: This endearing sound is used by mother opossums to call their babies back to her. It is typically heard when the mother is caring for her young, ensuring they stay close and safe.
4. Screeching or Screaming
- Characteristics: High-pitched, loud, and alarming.
- Purpose: Distress signal or expression of extreme fear.
- Context: Opossums may screech when they are in pain or terrified, such as when they are attacked by another animal or caught in a trap. This sound is rare but intense and immediately signals that the animal is in distress.
5. Snarling
- Characteristics: Low, prolonged, and aggressive.
- Purpose: Displays dominance or a heightened state of alert.
- Context: Snarling is most often used during fights or in territorial confrontations with other opossums or animals. It signals that the opossum is willing to defend itself if necessary.
Table of Opossum Sound Characteristics and Contexts
| Sound | Characteristics | Purpose | Behavioral Context |
|---|---|---|---|
| Hissing | High-pitched, sharp | Defensive behavior | When encountering predators or threats |
| Growling | Low, guttural | Aggressive warning | During confrontations or feeling cornered |
| Clicking/Smacking | Soft, rhythmic | Maternal communication | When calling young opossums |
| Screeching | High-pitched, loud | Distress signal | When highly stressed or in pain |
| Snarling | Low, prolonged | Aggressive display | During fights or defending territory |
How Opossums Use These Sounds
Though opossums are not highly social, they do use these vocalizations to express different states of being. For example, mothers use soft clicks to maintain contact with their young, while hissing and growling are more common in interactions with potential threats. By interpreting these sounds, one can better understand the opossum’s behavior and state of mind.
Common Scenarios Where You Might Hear Opossum Sounds
1. Nighttime Activity Near Homes
Opossums are nocturnal and often roam residential areas looking for food or shelter. Homeowners may hear sounds such as rustling, hissing, or even screeching at night. These noises may come from:
- Under Decks or Porches: Where opossums may hide or build temporary shelters.
- Near Trash Bins: Scavenging for food.
- In Trees: Searching for fruit or small insects.
2. Mother and Young Interaction
Mother opossums communicate with their young through soft clicking sounds. If a mother feels her joeys are too far away or needs to gather them quickly, she will make these reassuring noises. This sound indicates maternal care and bonding.
3. Defensive Encounters
An opossum faced with a dog, cat, or human will likely hiss or growl. If the threat persists or escalates, the animal may resort to playing dead as a final defense, a behavior known as “thanatosis.” While playing dead, the opossum becomes completely silent and limp to discourage predators.
How to Identify If Opossums Are Making the Noise
Differentiating opossum sounds from those of raccoons, squirrels, or birds can be tricky. Here’s how to tell them apart:
- Hissing: Raccoons and opossums both hiss, but opossum hissing is usually more abrupt and high-pitched.
- Growling: Opossum growls are typically softer and lower than the loud growls of raccoons.
- Screeching: Birds can screech too, but opossum screeches are distinct in their sudden, distressed nature.
How to Manage Opossum Sounds Around Your Home
To coexist with opossums peacefully and minimize nighttime disturbances, consider the following steps:
- Secure Trash Bins: Use animal-proof trash bins to prevent opossums from foraging.
- Block Entry Points: Seal off spaces under porches, decks, or sheds where opossums might nest.
- Keep Pet Food Inside: Opossums are attracted to pet food left outside.
- Use Deterrents: Motion-activated lights or water sprinklers can discourage opossums from frequenting your yard.
Fun Facts About Opossum Sounds and Behavior
- Limited Sound Range: Opossums only use vocalizations when necessary, unlike more social animals that rely heavily on sound.
- Chirping Joeys: Baby opossums make a unique chirping noise to signal their mother if they get lost or separated.
- Silent Scavengers: Despite their range of sounds, opossums are often silent while scavenging, relying on their sense of smell and hearing more than vocal cues.
What to Do if You Encounter an Opossum
If you happen to come across an opossum making noise:
- Stay Calm: Avoid sudden movements that might startle the animal.
- Give Space: Most opossums will retreat if given the opportunity.
- Avoid Handling: Opossums can carry diseases and parasites, so it’s best to contact animal control if necessary.
Conclusion
Understanding the different sounds opossums make can deepen your appreciation for these often-misunderstood marsupials. Whether it’s a mother opossum clicking to her young or a defensive hiss when cornered, each sound serves a purpose in their solitary world. By identifying these noises and knowing how to respond, you can coexist peacefully with opossums while learning more about their fascinating behavior.
