The Florida scrub-jay, the only bird species endemic to Florida, has become an icon of the state’s vanishing oak scrub habitats. Decades of habitat loss and fragmentation have left remaining populations isolated in small patches, where inbreeding and lost genetic variation can erode fertility, survival and resilience to disease. Deaner’s project builds on regional recovery efforts that began in the late 1990s through mitigation work led by the Mosaic Company, with early guidance from the late Reed Bowman, a prominent Florida avian biologist. Today, Raoul Boughton, senior manager of ecology and wildlife at the Mosaic Company, leads the recovery effort, with Deaner and Sahas Barve, program director of avian ecology at Archbold Biological Station, serving as co-principal investigators. Their collaboration spans wildlife managers, academic geneticists and field ecologists, reflecting the interdisciplinary scope that modern species recovery demands.

The scale of this translocation sets it apart. Previous scrub-jay relocations typically involved moving small numbers of birds over several years, producing gradual, hard-to-interpret changes. This time, researchers translocated 48 Florida scrub-jays to a new recipient site in one coordinated effort, enough birds to fill the site to its estimated carrying capacity. Every one of the 48 birds hatched in 2025, a deliberate design choice that eliminated age-related competitive advantages and allowed the team to observe how a cohort of young birds establishes itself from a level starting point. The result is essentially a controlled experiment in population establishment, replicated at a landscape scale that no previous scrub-jay study has attempted.

What happened next surprised even the researchers. Florida scrub-jays typically delay breeding, usually not becoming breeders until they are 2 or 3 years old, and younger birds instead remain on their parents’ territories as helpers, feeding nestlings and defending the family group. Across six decades of monitoring at Archbold Biological Station and two decades of data from the local population, fewer than 0.25 percent of recorded nesting attempts involved pairs of one-year-old birds. Yet at the recipient site, just six months after the translocation, four of the 10 newly formed pairs of one-year-old birds attempted to nest, a rate of 40 percent. The team had expected roughly half of the groups to include young birds serving as helpers; instead, most of the translocated jays sought their own breeding territories almost immediately.

That precocious breeding behavior matters far beyond its novelty. Genetic rescue ultimately works only if translocated individuals survive, find mates, reproduce and pass their genetic variation into the recipient population. The nesting attempts signal that the founding birds are not merely persisting but actively claiming territories and pairing up, giving researchers an early window into whether and how genetic integration will occur. While it remains too soon to measure the translocation’s long-term effects, the speed of establishment suggests the young birds detected something unusual about their circumstances, whether the absence of older competitors, the availability of vacant habitat, or some combination of social and ecological cues, and responded by accelerating their life histories.

The scientific machinery behind the project combines two powerful data streams. Genomic sequencing allows the team to examine patterns of genetic variation among source populations, identifying how different lineages have diverged and which combinations of breeding might maximize heterozygosity and minimize inbreeding in the next generation. Meanwhile, long-term field monitoring, the kind of painstaking, bird-by-bird observation that Deaner and her colleagues have honed over decades, provides the demographic reality check: survival rates, reproductive output, territory establishment, dispersal distances and population growth. The team integrates both streams using Vortex, a population viability analysis software that models how genetic, environmental and demographic factors interact to affect a species’ probability of persistence. By running scenarios with and without genetic rescue, the researchers can quantify how much a single large translocation might shift the population’s trajectory decades into the future.

Innovative tracking technology adds another layer of precision. Each translocated jay carries an RFID tag, and the team established feeding stations where a bird must stand on an antenna to access peanuts. Every visit is automatically recorded, giving Deaner a continuous, individual-level log of presence and social feeding behavior. Those visitation patterns do more than confirm survival; they may reveal the subtle early signatures of pair formation, as two birds begin appearing at the same stations at overlapping times. Identifying emerging pairs quickly allows the researchers to target those birds for intensive reproductive monitoring, locating nests, confirming clutch sizes and, eventually, sampling chicks for genetic analysis to confirm which parents contributed which alleles to the next generation.

Deaner’s path to this project runs directly through the species itself. Between earning her undergraduate degree at the University of Delaware and her master’s degree at Georgia Southern University, she spent six years conducting early translocations involving the very same Florida scrub-jay population she studies today. Collecting those field data, she says, and knowing that so many answers lie just beneath the surface of each spreadsheet, is what first inspired her to pursue graduate school. After completing her master’s degree, she returned to the scrub-jay recovery project, where the experience reinforced her conviction that genetic recovery is essential to the population’s long-term persistence. At UCF, she found an academic home that could match her field experience with analytical firepower. She conducts her research in the Conservation Genomics Lab of Eric Hoffman, chair and professor in the UCF Department of Biology, working alongside students tackling parallel conservation questions. Her dissertation weaves together conservation genomics, population ecology, behavioral ecology, spatial analysis and population modeling, an integration she credits to the university’s collaborative and interdisciplinary approach to biology.

The implications of the work extend well beyond a single species. If the scrub-jay translocation demonstrates that a one-time, carrying-capacity introduction of young, genetically diverse individuals can jump-start population recovery, it could reshape how managers design rescue programs for other imperiled species, potentially achieving results faster and with fewer resources than incremental translocations spread over many years. Deaner hopes the research will ultimately help conservationists recover imperiled species more quickly and more efficiently, turning genetics from a diagnostic tool into an active lever for restoration. In September, she will present preliminary findings at the International Conservation Translocation Conference in Edinburgh, Scotland, sharing early results with a global community of translocation practitioners.

For Deaner, the project is also a testament to a philosophy of curiosity-driven science. It is not the taxon that matters, she says, but the questions; as long as the questions are the ones that trigger your curiosity, you are heading in the right direction. With 48 young jays establishing territories, pairing up and attempting nests in habitat where their genes have never flowed before, the questions she has pursued for nearly twenty years are finally being answered in real time, one banded bird and one RFID log entry at a time, in the scrublands of central Florida.

As urbanization and industrialization continue to encroach upon natural habitats, the likelihood of human-wildlife conflicts escalates. Large carnivores, including species such as wolves, bears, and cougars, find their territories under siege, leading to increased incidents of livestock predation, property damage, and sometimes even threats to human life. This scenario necessitates a comprehensive strategy that not only identifies potential conflict zones but also involves local communities in the resolution process. The researchers argue that engaging communities in the conservation dialogue can significantly enhance the understanding of large carnivore behaviors and promote sustainable practices.

The core of the research methodology employed by the team revolves around a community-based participatory approach. This approach emphasizes the inclusion of local residents in data collection and conflict prediction efforts. By harnessing the knowledge and experiences of those who live closest to wildlife habitats, the researchers argue that the accuracy of conflict prediction can be greatly enhanced. Community members often have invaluable insights into animal movement patterns and the environmental factors that influence these behaviors, which can be instrumental in shaping conflict mitigation strategies.

Utilizing advanced technology such as GPS collars and motion-sensing cameras, the study incorporates quantitative data that complements local knowledge. These technologies provide critical information regarding the habitat use and travel corridors of large carnivores, painting a clearer picture of their interactions with human-dominated landscapes. By merging scientific data with on-the-ground community observations, the researchers develop a more robust framework for predicting potential conflict scenarios.

Moreover, the study details various intervention strategies that communities can adopt to minimize encounters with large carnivores. These include implementing protective measures for livestock, utilizing deterrents such as guard dogs or noise-making devices, and creating awareness programs that educate residents about safe practices when encountering these animals. By fostering a culture of coexistence and respect for wildlife, communities can lessen their vulnerability while simultaneously promoting the conservation of large carnivores.

An integral aspect of the study emphasizes the importance of building trust between researchers, wildlife managers, and local communities. Effective communication and collaboration are paramount in this initiative. The researchers advocate for consistent engagement with community stakeholders throughout the research process, ensuring that their voices are heard and their perspectives are valued. This participatory model not only strengthens community buy-in but also galvanizes collective action toward wildlife conservation.

The findings of this research are anticipated to have far-reaching implications. By providing a scalable and adaptable model for conflict prediction and management, this study could serve as a blueprint for various regions grappling with similar wildlife-human interaction challenges. The frameworks established could be tailored to fit specific environmental contexts, cultural norms, and community structures, thereby enhancing their effectiveness.

The researchers also highlight the role of policy in addressing human-carnivore conflicts. With the implementation of evidence-based strategies derived from community insights and scientific analyses, policymakers can foster an environment conducive to coexistence. Looking ahead, the study makes recommendations for integrating conflict management strategies into broader land use planning and conservation efforts to ensure that both humans and wildlife can thrive in shared landscapes.

In a world grappling with rapid environmental change, the urgent need to harmonize human activities with ecological preservation could not be more pressing. Large carnivores play a critical role in maintaining ecosystem balance as apex predators, and safeguarding their habitats is not just a matter of conservation but also a necessity for the health of our planet. The research presented in this study underscores the intricate interplay between human development and wildlife conservation, urging stakeholders to work collaboratively toward sustainable solutions.

As the research awaits its publication, the initial responses from fellow conservationists and community leaders have been overwhelmingly positive. There is a palpable enthusiasm around the potential influence of this study, with many anticipating that it will spark a more significant dialogue about human-wildlife coexistence. The spirit of collaboration and innovation that permeates this research is emblematic of the transformative potential inherent in community-based conservation efforts, where wisdom from local populations can meet scientific rigor for a better future.

In conclusion, Fedyń et al.’s imperative research demonstrates that large carnivore conflicts need not be an inevitable consequence of human encroachment onto wildlife territories. Instead, through community engagement and innovative technological applications, there exists an opportunity to recalibrate the relationship between humans and wildlife. The path forward lies in mutual respect, understanding, and a commitment to cohabitating this planet, where both large carnivores and human populations can flourish side by side. With further developments in this exciting research area, the hope is to see tangible changes in both policy and practice that effectively safeguard our natural heritage.

It doesn’t require a degree in ornithology, a lab test or even an app for most growers to determine whether bird poop near their crops presents a food safety risk. They just need to ask themselves a simple question: How big is it? 

That’s according to a study from the University of California, Davis, published today in the Journal of Applied Ecology. The study said an informed, nuanced view of food-safety risks and wild birds could help growers avoid crop losses and manage farms for food safety, biodiversity conservation and crop production.

Since 2006, when an E. coli outbreak devastated the U.S. leafy greens industry, growers have been pressured to remove natural habitat to keep wildlife — and the foodborne pathogens they sometimes carry — from visiting crops. Growers are often advised not to harvest crops within a roughly three-foot radius of any wildlife feces, lest they risk failing a food safety audit or losing a buyer contract. Growers often cite such concerns as a barrier to implementing conservation actions they would otherwise consider taking on their farms. 

“We wanted to find out the true risk of wild birds to food safety,” said lead author Austin Spence, a postdoctoral researcher in the UC Davis Department of Wildlife, Fish and Conservation Biology. “Which birds have pathogens, which birds are spending time on farms, and if a bird has a pathogen, does that pathogen survive long in bird poop? Our findings indicate that we can co-manage our areas for both agriculture and conservation.”

Where pathogens persist

Through field and greenhouse experiments, bird surveys, point counts and fecal transects, the authors assessed food-safety risks from nearly 10,000 birds across 29 lettuce farms on California’s Central Coast. They spent hours following turkeys, bluebirds and other wild birds at the UC Davis Student Farm and nearby Putah Creek, collecting hundreds of fecal samples. They compared E. coli survival in bird droppings on lettuce, soil and plastic mulch to measure pathogen persistence.

After all of these efforts, they landed on a simple finding: Smaller poops from smaller birds carry very low risk of foodborne pathogens, which were rare in birds overall. If a bird were to become infected, pathogen survival depends heavily on the bird’s size. 

“Birds that are large produce really big feces, and that’s where pathogens are more likely to survive,” said Spence. “Birds that are small have tiny feces, and the pathogens die off quickly. So farmers don’t have to know the species of bird it came from. They just need to know the size. If it’s the size of a quarter, don’t harvest near that. If it’s a tiny white speck, it’s very low risk and probably fine.”

Balancing conservation, crop yields, and food safety

Beyond fecal size, what the birds pooped on — be it the crop, soil or plastic — made a difference for pathogen survival. In the study, E. coli survived longer on lettuce itself than on soil or plastic mulch. 

Fortunately, about 90% of birds observed on the farms were small and tended to poop mostly on soil, where pathogens perish quickly. By avoiding no-harvest buffers when food-safety risks are low, growers of leafy greens could harvest about 10% more of their fields. 

“Birds generally present really low food-safety risks,” said senior author Daniel Karp, a UC Davis professor in the Department of Wildlife, Fish, and Conservation Biology. “The industry has been concerned about birds for a while. But pathogenic E. coli and Salmonella are vanishingly rare in wild, farmland birds. And we now know E. coli tends to die off quickly in most bird poop.”

The study opens up new strategies for growers to better balance conservation and food-safety risks. For example, growers could erect nest boxes to attract small, beneficial insect-eating birds, like bluebirds and swallows, that help control pests without risking food safety. 

The work also contributes to a growing body of research that suggests growers do not need to remove habitat to improve food safety. 

“There have been no studies to date that suggest habitat removal improves food safety,” Karp said. “Habitat around farms is actually likely to favor the small, insect-eating birds that are unlikely to carry pathogens. Studies like ours are giving farmers science-based permission to conserve habitat — and many species of wild birds — on their farms again.”

The study’s additional coauthors are Jeffery McGarvey and SangIn Lee at the USDA Agricultural Research Service, Olivia Smith at Michigan State University, Elissa Olimpi at Conservation Science Partners, and undergraduates Wentao Yang and Meirun Zhang at UC Davis.
