Burrowing Owls Face Extinction Threats as California Developers Claim Vital Habitat

Burrowing Owls Face Extinction Threats as California Developers Claim Vital Habitat

The Western Burrowing Owl, native to the open grasslands and deserts of North America, faces a tough battle for survival. This small owl, known for its bright yellow eyes and preference for underground burrows, is now at the center of an intense conservation effort. California officials have granted it “candidate” status for endangered species protection, a significant move that could influence the fate of this unusual bird throughout the state.

According to experts, Western Burrowing Owl populations have dwindled dramatically across California. Once common in places like the Bay Area, where hundreds of pairs nested, the owls are now almost gone, with fewer than 25 breeding pairs remaining in that region The Los Angeles Times reports. As urban development and agricultural expansion carve up the owls' habitat, conservationists are pushing harder than ever to ensure their protection.

How Habitat Loss and Development Endanger the Owls

Burrowing Owls rely on grasslands and other open spaces where they can hunt insects and small mammals. They nest in burrows, often ones abandoned by ground squirrels or other small creatures. But as cities expand, these vital habitats are becoming rare, forcing the owls into smaller, isolated patches. Pamela Flick, California Program Director at Defenders of Wildlife, told  The Independent that this matter was “truly concerning,” especially as these owls have lost about one-third of their historic range.

Urban sprawl isn’t the only issue. In addition to habitat loss, renewable energy projects—particularly wind farms—pose a unique danger. The owls, which are poor fliers compared to other birds of prey, risk fatal encounters with wind turbines. Furthermore, the very ground squirrels that burrowing owls depend on for shelter are often targeted by pest control measures, leaving the owls with even fewer options for nesting sites The Center for Biological Diversity notes.

The Path to Protection

Earlier this year, conservation groups, including Defenders of Wildlife and the Burrowing Owl Preservation Society, filed a petition to classify the owls as endangered or threatened under California law. This wasn’t their first attempt. In 2003, a similar petition failed, but conservation advocates believe the current environmental and political climate offers a better chance for success.

Jeff Miller, a senior conservation advocate, calls the situation for these owls “an emergency,” as they’ve already disappeared from many of their former strongholds, according to the Local News Matters.

If approved, the owls would receive immediate protection during a status review by the California Department of Fish and Wildlife, expected to take up to 18 months. This candidate status offers a reprieve, preventing land developers from evicting owls from areas under construction. Should they receive full protection, state and local agencies would also need to adopt more stringent measures to safeguard their remaining habitats.

A Complex Web of Threats

Burrowing Owls are no strangers to adversity. In addition to habitat loss, these birds face direct dangers from pesticides and rodenticides used in agricultural areas, which often find their way into the owls’ food sources. Vehicle collisions and predation by non-native species like domestic cats add to the mortality rate, while climate change threatens to reshape the grasslands where these owls thrive. As the Stanford Conservation Program explains, these cumulative pressures have pushed the owls to the edge in many parts of the state.

In recent years, the loss has been especially evident in counties along the coast, such as San Francisco and Santa Clara, where burrowing owls have almost entirely disappeared. State wildlife officials note that the Central Valley remains one of the last strongholds for the species, but even there, the pressures are mounting. One promising approach has involved preserving patches of habitat specifically for these owls, but long-term success will likely require statewide coordination to address the broader range of threats they face.

Conservation Efforts and What Comes Next

Efforts to save the Western Burrowing Owl extend beyond simple land protections. Conservationists are advocating for more public awareness and have worked with local governments to install artificial burrows in areas where natural ones have disappeared. According to the The Los Angeles Times, some local governments and private landowners have embraced these measures, which may provide temporary relief while long-term solutions take shape.

Ultimately, the California Fish and Game Commission will decide whether the burrowing owl’s status warrants formal listing as endangered or threatened. Conservationists like Miller remain optimistic but understand the road ahead will be challenging. For now, the candidate status provides a critical buffer, but the fate of these quirky, ground-dwelling birds will depend on sustained and coordinated conservation efforts.
