Burrowing Owls: A Guide to Their Unique Underground Lifestyle
Characteristics and Appearance
Burrowing owls (Athene cunicularia) are small, sandy-colored owls with distinctive bright-yellow eyes. They typically measure between 8-10 inches in length and have a wingspan of around 2 feet. Their sandy coloration serves as effective camouflage in the arid environments they inhabit.
Underground Living
Unlike most owls, burrowing owls do not build nests in trees. Instead, they reside underground in burrows that they either dig themselves or take over from other burrow-dwelling animals, such as prairie dogs. These burrows provide shelter from predators and the elements, and can extend several feet underground.
Habitat and Distribution
Burrowing owls primarily inhabit open grasslands, prairies, and deserts in North and South America. They are found in areas with sparse vegetation, providing them with clear views of their surroundings. They are known for their adaptability, and can tolerate a wide range of environmental conditions, including arid climates and high elevations.
Hunting Habits and Diet
Burrowing owls are primarily active at dusk and dawn, hunting for prey in their open grassland habitats. Their diet consists primarily of insects, rodents, and small mammals. They use their sharp talons and curved beaks to capture and kill their prey.
Conservation Status and Threats
Burrowing owls face a number of threats to their survival, including habitat loss, pesticide use, and climate change. Urban development and agricultural practices have reduced their available habitat, and the use of pesticides has contributed to the decline of their prey base. Climate change is also affecting their distribution and behavior patterns.
