Lab Overview
NRRI’s Avian Ecology Lab is an applied research program that has been studying the direct impacts of environmental change on wildlife, biodiversity, habitats, and ecosystem function for over 30 years. Using the best available technology and field techniques we gather critical data on avian and amphibian communities with a focus on species of conservation concern and vulnerable habitats. Our ecosystem-based programs focus on using birds as environmental indicators to learn about ecosystem function and implications of natural resource use and climate change. Our species-based research focuses on studying species’ ecology including assessment of diet, behavior, and habitat needs during breeding, post-breeding and migration. These data help us understand impacts of invasive species, management, restoration, and climate on ecosystem function in a rapidly changing world. Our commitment is to use this information to develop management and conservation strategies aimed at protecting biodiversity.
Lab Goals
- Conduct research that contributes to knowledge of avian conservation and ecology through a combination of original research, long-term and ecological effects monitoring, education, and stakeholder engagement to develop conservation strategies to preserve and enhance species diversity.
- Develop and conduct research projects that address current and emerging threats to biodiversity.
- Improve understanding of ecosystem function, habitat, and species-specific needs to inform conservation and management.
- Disseminate information to stakeholders to provide guidance and support resource management decisions to conserve biodiversity.

Lab Tools and Techniques
- Autonomous recording units: We deploy these audio recording devices in a variety of habitats to complement point count surveys.
- Camera traps: We use camera traps to collect data for several projects including assessment of songbird predation and stopover use of migrating shorebirds.
- Drones: Drones are used in our research for monitoring and habitat assessments.
- eDNA: We use DNA metabarcoding and next- generation sequencing techniques to understand the diet of focal species.
- Habitat assessments: We conduct in-depth vegetation surveys to quantify habitat characteristics that are important for focal species.
- Insects: We conduct insect surveys to understand food availability and abundance for focal species during the breeding season.
- Isotopes: We use isotopes to study ecosystem processes including diet assessment and impacts of contamination for focal species.
- Point count and line transect surveys: Field crew undergo rigorous training to be able to identify over 100 species by sight and song. Over 1,000 point counts are conducted annually by our team of experts!
- Small mammal surveys: We conduct small mammal surveys to determine the presence and abundance of small mammals in focal habitats and ecosystems.
- Tracking: We use a variety of tracking technologies including geolocators, GSM and GPS tags, RFID, Motus and hand-held telemetry to study movement ecology of focal species.
