Bird flu resurfaces in chicken, turkey flocks, in midst of fall migration

Nov 7, 2023

Across the U.S., cases of highly pathogenic avian influenza are ramping up again in commercial chicken and turkey flocks as well as backyard flocks. HPAI, commonly known as bird flu, is a highly contagious viral disease that is fatal to chickens and turkeys. According to the U.S. Department of Agriculture, more than 60 million commercial and backyard birds in the U.S. have died from the disease or been killed to contain its spread, since the current, ongoing outbreak first hit U.S. commercial flocks in early 2022.

Wild bird migrations are an especially important signal to the Delmarva Peninsula, a major broiler chicken producing region, that HPAI could be near.

“In the Atlantic Flyway, extending from the northern Delmarva down to the Carolinas, that’s where the bulk of the Atlantic Flyway birds overwinter,” said Jeffrey Buler, a professor of wildlife ecology in the University of Delaware College of Agriculture and Natural Resources. “We get tens of thousands of snow geese that are here in the winter, and they’re just starting to arrive.”

Wild birds, particularly waterfowl, can shed the virus through their saliva or feces. Around this time of year, waterfowl are migrating south, to their wintering grounds.

Buler is part of a team of scientists from the University of Delaware, the University of California, Davis, and the U.S. Geological Survey that has been researching using weather radar to track migrating wild birds that could be carrying avian influenza viruses.

“It gives us an idea of where and when these migrations are happening,” Buler said. “So ultimately, the poultry industry can ramp up their biosecurity.”

Buler can talk about wild bird migrations, what types of migratory birds we tend to see in Delaware this time of year, trends in fall migration and climate, and ongoing weather radar research.

Experts on earthquake response, community recovery and building safety

The shaking from a major earthquake may be over in minutes, but its consequences will last for years. University of Delaware experts can address emergency response, distributing aid, assessing damaged buildings, helping vulnerable communities and planning for long-term recovery. Their expertise is particularly relevant as communities across Latin America respond to major earthquakes, including the deadly magnitude 7.4 earthquake in Colombia. Tricia Wachtendorf, co-director of UD’s Disaster Research Center, offers expertise on how governments, nonprofits, emergency responders and community groups coordinate following a major disaster. Her research examines the role of spontaneous or “emergent” groups, humanitarian aid and donations, and how communities and organizations respond in the aftermath of disasters. Jennifer Trivedi, associate professor of anthropology and Disaster Research Center faculty member, specializes in disaster vulnerability and why some communities are more severely affected than others. She also addresses the long-term recovery needs and planning that emerge after the immediate crisis. Michael Chajes, professor of civil and environmental engineering, provides expertise on the structural damage caused by earthquakes, why some buildings collapse while others withstand the shaking and how engineers assess damaged structures and improve earthquake resilience.

Mapping the ancient world with underwater robotics

As audiences flock to theaters for Christopher Nolan's The Odyssey, University of Delaware professor Art Trembanis is leading a real-life expedition to uncover one of ancient Greece's most important maritime landscapes. Trembanis, a professor in UD's School of Marine Science and Policy and an expert in seafloor mapping, marine robotics and underwater sensing technologies, recently led a team of students and researchers to the ancient harbor of Kenchreai, where they deployed autonomous underwater vehicles, advanced sonar systems and other cutting-edge mapping technologies to document a harbor that has remained hidden beneath the Mediterranean Sea for centuries. The expedition collected geospatial data that will allow researchers to reconstruct the ancient port in remarkable detail and ultimately create a "digital twin" of the site. The virtual model will enable archaeologists, engineers, students and the public to explore the harbor as if the water had been removed, preserving an invaluable piece of cultural heritage while advancing the use of marine technology in archaeology. Trembanis can discuss: Marine robotics and autonomous underwater vehicles Seafloor mapping and underwater imaging technologies The use of digital twins and 3D modeling to study underwater environments Advances in marine geospatial technology and ocean exploration Underwater archaeology and documenting submerged cultural heritage How engineering and marine science are transforming the study of oceans and ancient landscapes The role of emerging technologies in scientific discovery and education To arrange an interview with Trembanis, click on his profile or email mediarelations@udel.edu.

How Wildfires Impact Vulnerable Communities, Pets and Public Health Systems

Wildfires burning across the world, now in parts of France and Spain, are forcing hundreds of thousands of people to evacuate. University of Delaware experts are available to discuss wildfire evacuations, vulnerable communities, animal rescue and the health effects of wildfire smoke exposure. Those experts, from UD’s Disaster Research Center, include: Sarah DeYoung Professor of sociology and criminal justice: • How people are forced to make split-second decisions involving horses, livestock and companion animals during fast-moving wildfires. • Why some owners must turn animals loose when evacuation time is limited. • Lessons from past disasters and animal rescue research. Jennifer Trivedi Assistant professor of anthropology: • The unique challenges faced by vulnerable populations during wildfires. • Complications surrounding evacuation decision-making and evacuation needs. • Long-term recovery following catastrophic disasters. Jennifer Horney Chair of UD’s Department of Epidemiology: • Health risks associated with wildfire smoke exposure, including respiratory infections. • How wildfire smoke and airborne pollutants affect population health. • The strain major wildfires can place on public health and health care systems.
