The Return of the Quail: How Conservation Efforts are Bringing Back a Once-Extinct Bird in Pennsylvania

Apr 3, 2024

2 min

Over the next three years, the Pennsylvania Game Commission, the University of Delaware and other partners will release about 100 northern bobwhite quail per year on Letterkenny Army Depot in southern Pennsylvania. The birds have been considered eradicated for at least 20 years in the area.

Chris Williams, a professor of wildlife ecology and the director of the Waterfowl and Upland Gamebird Center, is the lead investigator on the project.

“When we think about the greater concerns about wildlife biodiversity and conservation and changing environments, to see extinctions occur in such a short time frame is scary,” Williams said. “And it’s really exciting when we can take chances to try to find a way to bring them back and make sure it’s a long term success.”

The researchers hope to help the state’s quail population rebound and evaluate what can be learned from how they acclimate and apply it to similar projects. Two University of Delaware graduate students will work with the researchers to study the quail reintroduction and how songbirds at the site react to it. Each bird has been equipped with a radio transmitter so the researchers can track their movement and survival on the landscape.

More than 70 bobwhite quail have been released at the site in recent weeks, including the release of 50 bobwhite quail during a March 19 event.

Jeffrey Buler, a professor of wildlife ecology and the co-principal investigator on the project, said other bird species are also an important focus of this project.

Can AI save our oyster reefs? A team of scientists put it to the test

With global oyster populations having declined by more than 85% from historical levels, restoring and monitoring these critical ecosystems is more urgent than ever. But traditional monitoring methods aren’t cutting it. A team of researchers that included the University of Delaware's Art Trembanis have taken a new approach, testing an AI model designed to recognize live oysters from underwater images. The findings? The AI model, called ODYSSEE, was faster than human experts and non-expert annotators, processing in just 40 seconds what took humans up to 4.5 hours. But it wasn’t yet as accurate. In fact, the tool misidentified more live oysters than both groups of human annotators. Still, the team found that ODYSEE has real potential to monitor reefs in real time. Why does this matter? As climate change, pollution and overharvesting continue to pressure coastal environments, more precise and non-invasive monitoring tools like ODYSSEE could become essential to restoration efforts and environmental policy. Trembanis can discuss this new tool and its ability to identify live oysters without disturbing the reef. His expertise in oceanography, engineering and robotics expertise was key to the team's work. The results, published in the journal Frontiers, offer both caution and hope in the race to improve ocean monitoring with emerging technologies.

Will AI undermine or support writing and critical thinking?

As artificial intelligence reshapes the way we write and think, a central question emerges: Is AI helping or hindering our ability to engage in independent, critical thought? Joshua Wilson, professor of education at the University of Delaware, investigates this topic in a new paper that examines the risks of AI dependency and discusses the need for AI literacy in education. Wilson explores how AI impacts cognitive development through writing — highlighting both the promise and peril of AI-powered tools like ChatGPT. His expertise centers on how these tools interact with foundational models of writing and learning and what that means for education, workforce readiness and civic engagement. In his new paper, Wilson warns that while AI can support higher-order thinking by automating basic writing mechanics, it also risks eroding critical thinking if students and professionals come to rely on it uncritically. He is a leading advocate for AI literacy in education – training individuals not just to use AI, but to think with it. Wilson is available for interviews with reporters, particularly those covering the intersection of AI, education and society and investigating the risks of cognitive offloading in an AI-saturated world.

Fast-striking and unpredictable, tornadoes pose major challenges for emergency planners

At least 20 U.S. states have been hit with tornadoes – some of them deadly – over the past week. Experts from the University of Delaware's Disaster Research Center can speak to the difficulty of drawing up plans in advance of tornadoes, which can develop quickly and unexpectedly, as well as a variety of topics related to storm preparedness, evacuations and recovery. Those experts include: Jennifer Horney: Environmental impacts of disasters and potential public health impacts for chronic and infectious diseases. Horney, who co-authored a paper on the increase in tornado outbreaks, can talk about how impacts on the morbidity and mortality that result from tornadoes. Tricia Wachtendorf: Evacuation decision-making, disaster response and coordination, disaster relief (donations) and logistics, volunteer and emergent efforts, social vulnerability. James Kendra: Disaster response, nursing homes and hospitals, volunteers, response coordination. Jennifer Trivedi: Challenges for people with disabilities during disaster, cultural issues and long-term recovery. Sarah DeYoung: Pets in emergencies, infant feeding in disasters and decision-making in evacuation. A.R. Siders: Expert on sea level rise and managed retreat – the concept of planned community movement away from flood-prone areas.
