Researchers with the Borderlands Research Institute are conducting a detailed study of high-elevation owl populations in the Davis Mountains, using advanced monitoring technology to better understand nocturnal bird species in the region.
The project focuses on how “sky island” mountain ranges within the Chihuahuan Desert create cooler, wetter conditions than surrounding lowlands. These isolated environments support plant and animal communities that differ from those found in nearby desert areas, including bird species typically associated with higher elevations.
Because of the rugged terrain and remote location of the mountains, scientists say information about many high-elevation and nighttime birds remains limited. Traditional survey methods can be difficult to use in the area, particularly after dark, when many species are most active.
To address those challenges, researchers are using passive acoustic monitoring devices placed in forested areas. The equipment records nighttime calls, which are later analyzed using deep-learning computer models designed to identify species based on vocal patterns.
The study is led by a graduate researcher named Shelby and centers on determining where and how often certain owls occur in the mountains. Particular attention is being given to flammulated owls and northern saw-whet owls, two small, elusive species that are rarely observed directly.
By combining fieldwork with artificial intelligence tools, scientists hope to improve detection rates and build a clearer picture of how these birds use high-elevation habitats throughout the year.
Institute officials said the findings will help guide future conservation and management efforts in West Texas mountain ecosystems and contribute to a broader understanding of desert “sky island” wildlife communities.
