Foxes, often found in both urban and rural landscapes, are frequently heard vocalizing throughout the night. These nocturnal sounds can sometimes be startling, leading many to wonder about their origin and purpose. Understanding why foxes make these varied noises offers insight into their complex communication and behaviors.
The Unique Sounds of Foxes
What humans often perceive as a singular “bark” from a fox is actually a diverse range of vocalizations, each serving a distinct purpose. Red foxes, a common species, can produce over 20 unique sounds. These include barks, screams, yips, growls, whimpers, and chirps. The specific sound a fox makes varies by species, age, and situation.
Fox barks are short, sharp, and high-pitched, differing from a domestic dog’s repetitive barks by being brief bursts. Screams, particularly the “vixen’s scream,” are loud, eerie, and drawn-out wailing sounds that some describe as resembling a human in distress. Other sounds, like “gekkering,” involve a rapid, staccato chattering noise heard during competitive or courtship interactions. Whines and whimpers are softer sounds, used between a mother fox and her young, or to signal submission.
Why Foxes Are So Vocal at Night
Foxes are largely crepuscular, most active during dusk and dawn, but are often heard throughout the night, especially in areas where human activity causes them to shift patterns to avoid people. Their nocturnal vocalizations are integral to their communication, serving various behavioral and biological needs. These sounds intensify during specific seasons, providing clear signals to other foxes.
One primary reason for nocturnal vocalizations is territorial marking and defense. Foxes use barks to warn others to stay out of their established territory, acting as auditory boundary markers. This helps maintain their individual or group space, especially when encountering intruders. A “wow-wow-wow” bark declares territory ownership.
Mating calls are another source of nighttime sounds, particularly during the breeding season, which occurs in winter from December through February. Female foxes, known as vixens, emit loud, high-pitched screams to attract male foxes from afar. These startling screams can travel long distances, sometimes up to five kilometers, and male foxes respond with their own calls, which are lower in pitch.
Foxes also vocalize to communicate with their kits, or young. Vixens use various sounds, including whines and whimpers, to interact with their pups, guiding them and teaching them behaviors like hunting. As kits mature, their vocalizations also develop, with infantile barks and yelps used during play and as contact calls. These calls help maintain cohesion within the family group and ensure the safety of the young.
Foxes also use calls to alert family members to perceived dangers. A rapid sequence of barks or yelps can serve as an alarm call, warning others about threats or intruders. These warning calls aid the group’s survival, ensuring all members are aware of potential predators or other disturbances. General social communication, such as maintaining contact within family groups or announcing their presence, also contributes to their nighttime vocal activity.
Living Alongside Nocturnal Foxes
Hearing the varied sounds of foxes at night is a normal aspect of their behavior. These vocalizations are particularly common during certain seasons, such as the winter breeding season when mating calls are frequent, and in spring and summer when parents are raising and dispersing their young. The sounds are part of their natural communication and do not indicate distress or danger for the animals themselves.
To coexist peacefully with foxes, it is helpful to understand their habits. They are shy animals and tend to avoid human interaction. Simple measures can help minimize potential conflicts or reduce their presence around homes. Securing garbage bins with tight-fitting lids prevents foxes from accessing food waste, and avoiding leaving pet food outdoors, especially at night, removes another potential food source. While foxes are harmless to humans, it is recommended to observe them from a distance and never attempt to approach or feed them.
