It’s type of laborious to not be smitten with the burrowing owl.
Standing simply 9 inches tall and weighing lower than a cup of espresso, these owls choose to reside within the floor, the place they feed primarily on bugs and small rodents, somewhat than in timber. Their miniature measurement, feathery floof and comically large eyes give these birds of prey a charisma that captivates the lens of wildlife photographers and the hearts of even probably the most scientific environmental scientists.
“When you see a burrowing owl, you simply fall in love,” mentioned Catherine Portman, president of the Burrowing Owl Preservation Society.
However their cuteness hasn’t protected this grassland species from a harmful decline in inhabitants. This month, a number of wildlife conservation teams petitioned the California Fish and Sport Fee to checklist these owls as endangered or threatened underneath the California Endangered Species Act.
Their report cites a 2007 statewide survey that measured an 11% decline in burrowing owls since 1993; though no complete inhabitants rely has be carried out since, they level to regional research that present troubling numbers. Researchers Robert L. Wilkerson and Rodney B. Siegel counted 6,408 burrowing owl pairs within the Imperial Valley from 2006-07, however in accordance with one other research carried out by Jeffrey Manning, greater than 1 in 4 breeding pairs had disappeared.
Shani Kleinhaus, a resident of Santa Clara Valley and environmental advocate with the native Audubon Society, remembers a time when it was straightforward to identify these raptors bobbing their heads all throughout the Bay Space, even of their camouflaged plumage.
“In 2009 we nonetheless had burrowing owls within the county that have been very accessible to the general public so folks might see them,” Kleinhaus shared. However now, she mentioned, most if not all of those birds depend on native conservation efforts to assist shield their dwindling habitat within the Bay Space and assist them pair after they attain reproductive maturity.
Why are the owls disappearing?
In response to the newest census, 70% of burrowing owls within the state of California reside within the Imperial Valley and surrounding areas in Southern California. As housing developments push farther and farther out from the state’s city cores and wind and photo voltaic farms increase in rural areas, these owls have discovered themselves generally competing with people for actual property.
However it’s just a little extra sophisticated than rapacious builders versus hapless birds; there’s loads of blame to unfold round.
Burrowing owls depend on floor squirrels to assist construct their nests, however farmers typically kill them as pests as a result of they nibble on electrical wiring and feed on produce. Feral cats and roving hounds have been recognized to hunt them down. Invasive grasses introduced by Spaniards through the late 1700s to feed their livestock have made grasslands much less liveable for floor squirrels and burrowing owls alike.
There are mitigation charges that builders pay if they’re encroaching on burrowing owl habitats. And the Migratory Fowl Treaty Act and the California Fish and Sport Fee codes afford protections to burrowing owls, however advocates say it’s not sufficient.

The decline of the owl is ‘loss of life by a thousand cuts’
These environmentalists have petitioned to guard the burrowing owl earlier than, most not too long ago in 2003 when scientists like Lynne Trulio seen a worrisome decline within the inhabitants of burrowing owls throughout the state. That petition was rejected as a result of the state famous that the owls have been flourishing within the Imperial Valley with the rise in agriculture within the Nineties.
“[Burrowing owls] ought to have been listed again then, for my part,” mentioned Trulio, chair of the environmental research division at San Jose State College. “What’s totally different 20 years on is that the pattern that we noticed in 2003 decline has steepened, and has gotten worse.”
Esther Burkett, senior environmental scientist at California Division of Fish and Wildlife, admits there aren’t sufficient authorized protections for the owls and that the state paperwork could make it tough to behave shortly. (Her division is to not be confused with the Fish and Sport Fee; her crew does the analysis that informs the coverage and guidelines that the Fish and Sport Fee decides.)
“You bought to know what you’re in search of. So, ideally, for any species, the precise surveyor must be educated on how to do this,” mentioned Burkett. “[If] you miss a assessment of that [California Environmental Quality Act] doc you don’t get one other likelihood at it. After which we’re gonna lose three [breeding] pairs and it’s simply loss of life by a thousand cuts over time.”
Burkett manages a big selection of species within the state and mentioned she’s overwhelmed by the necessity and the dearth of assets she has to handle the issues dealing with many of those animals. The final time they put collectively a complete report on burrowing owls was in 2012, and even that report took 4 years to place collectively. She likens the state of affairs to a hospital the place they’re making an attempt to handle many sufferers — species tagged as “particular curiosity” just like the burrowing owl are within the ICU, however most of their assets are going towards endangered and threatened species within the emergency room.
Activists intervene on the owls’ behalf
Portman spends numerous her time educating Californians tips on how to apply the California Environmental High quality Act to guard burrowing owls. The statute, which Gov. Ronald Reagan signed into regulation in 1970, requires builders to gauge the environmental results of their tasks and plan tips on how to mitigate them — and permits the general public to problem them. However it’s not all the time straightforward to verify these companies are doing their due diligence.
“I don’t put that on the developer. I put that on the land use jurisdictions,” mentioned Portman. The company tasked with making ready the environmental influence report often makes the developer bankroll it, and it’s within the developer’s pursuits to rush the undertaking towards completion. “Town councils, the county Board of Supervisors, whoever the lead company is, will get to determine how that land is used,” Portman mentioned, however they “don’t take full benefit of the authority that that they had.”
Different scientists are working to extend the possibilities burrowing owls can survive and efficiently reproduce. For instance, the San Diego Zoo Wildlife Alliance, which has been collaborating with companies and municipalities to save lots of the burrowing owl, not too long ago launched some owls that had been rescued from near-certain loss of life as chicks.
Jeff Miller, senior conservation advocate on the Heart for Organic Range, was creator of each petitions; he’s one of many few activists who remembers when biologists began sounding the alarm within the Nineties. Miller believes the result of this petition might be totally different as a result of the priorities of the fee have shifted over time.
Again when the Fish and Sport Fee started, Miller mentioned, “all the pieces was managed as to be fished or to be hunted.” Right now, extra board members have experience in environmental points, he mentioned, and “there’s much more emphasis on conserving imperiled species.” The commissioners didn’t reply to The Instances’ request for remark.

Burrowing owls and California’s grasslands
Burrowing owl advocates mentioned the purpose of itemizing the chook as an endangered species is to ultimately get it off the checklist. However Trulio thinks itemizing the chook underneath California’s Endangered Species Act might be the important thing to preserving the state’s grasslands.
Trulio’s speciality is city species, and she or he’s contributed to the analysis that underpins Santa Clara County’s habitat conservation plan on burrowing owls. However earlier than that she was additionally the lead scientist for the South Bay Salt Pond Restoration Mission, one of many largest tidal wetland restoration tasks on the West Coast.
“One of many issues that drove the trouble was the very fact that there have been endangered species” in wetlands, mentioned Trulio. She mentioned it took years to vary the notion of the wetlands as a dumping floor and to get a poll measure to fund its preservation.
The place builders would possibly have a look at grasslands as huge empty landscapes to construct on, Trulio mentioned, she sees their worth to the general public as areas for out of doors recreation and sequestering carbon to struggle local weather change. It’s not nearly defending this one species of chook, however the ecosystem they inhabit, Trulio mentioned.
“We have to shield burrowing owls earlier than urbanization takes maintain,” Trulio acknowledged. “As soon as urbanization takes maintain, what actually occurs is land values turn out to be so excessive you could’t shield them.”
The double-edge nature of visibility
Lauren Bettino, a Bay Space wildlife photographer, had by no means seen a burrowing owl earlier than she got down to Level Isabel Regional Shoreline to snap a photograph of those uncommon birds.
Bettino was taking a break from her search and sat down on a rock solely to comprehend she occurred to share a perch with a burrowing owl. “He was not involved about me in any respect,” Bettino recalled. “I spent most likely an hour and a half to 2 hours simply sitting subsequent to him and watching him.”
Bettino tries to not promote precise areas of the place she pictures wildlife as a result of it might entice over-zealous photographers who might disturb them. However she’s believes sharing photos of the burrowing owls is a vital strategy to encourage folks to care extra about their pure neighbors; she is aware of most individuals aren’t subject biologists.
The Audubon Society’s Instagram web page typically options burrowing owls the place they’re favored by hundreds of viewers. To Kleinhaus it is sensible why there’s such an outpouring of affection. “Seeing an owl opens your eyes to one thing very legendary or primordial,” she mentioned. “It elicits emotion not simply from me, however anybody who sees them.”
