Armadillos are distinctive mammals recognized by their unique armored shells and their habit of digging. The nine-banded armadillo, common across the Americas, often prompts questions about its daily routines. While encounters during daylight hours might seem unusual, their activity patterns are more adaptable than many realize. Understanding their typical behavior and the factors that influence it can shed light on why you might spot an armadillo out and about.
Understanding Armadillo Activity
Armadillos are primarily nocturnal, active during the night, and crepuscular, active during dawn and dusk. This pattern allows them to avoid extreme temperatures, as they are not highly efficient at regulating body temperature. With a lower metabolic rate, armadillos rely on burrows as thermal shelters to maintain a stable body temperature. They often spend up to 16 hours sleeping within these underground havens.
Their physiology, with a lower body temperature and minimal body fat, makes them susceptible to thermal stress. Burrows provide protection from summer heat and winter cold. This reliance on burrows dictates their foraging schedule, which typically occurs during cooler periods.
Reasons for Daytime Sightings
Armadillos can be observed during the day due to environmental and behavioral factors. Temperature plays a significant role in their decision to forage above ground in daylight. During colder months, especially winter, armadillos may shift their activity to the warmest parts of the day to find food when the ground is less frozen. This allows them to access insects and grubs.
Conversely, in extremely hot conditions, armadillos might emerge during cooler daytime periods, such as early mornings or late afternoons, if nighttime temperatures remain too high for effective foraging. Their burrows offer refuge from the midday heat, but a need for sustenance can prompt daytime excursions. If food sources become scarce at night, armadillos may extend their foraging into daylight hours.
Human activity can also influence armadillo behavior. In areas with less human disturbance, armadillos may exhibit more daytime activity. However, in urban environments, they tend to become more nocturnal to avoid human contact. Additionally, during breeding season or when caring for young, their activity patterns can temporarily change, leading to more frequent daytime sightings.
When to Be Concerned: Health and Safety
While daytime sightings are often a response to environmental conditions, certain behaviors warrant concern for the animal’s well-being and human safety. An armadillo exhibiting unusual actions, such as stumbling, disorientation, or lack of fear towards humans, may indicate illness. Normally, armadillos are timid and will attempt to flee or hide when approached.
Though rare, armadillos can carry the rabies virus. Any wild animal displaying aggression or disorientation could be infected. Their naturally lower body temperature makes them less common hosts for rabies, but cases have been documented. It is advisable to maintain a safe distance from any wild animal, particularly one that seems unwell.
If an armadillo appears sick, injured, or is in an unusual location, it is best to contact local animal control or a professional wildlife rescue organization. Attempting to handle or intervene with a wild animal directly can pose risks to both yourself and the animal. These professionals have the expertise and equipment to assess the situation safely and determine the appropriate course of action.
