Cerulean Warbler Field Technician

Position Summary

~4-6 field technician positions are available for early summer 2026 to contribute to a project through Purdue University studying migration ecology in a southern Indiana population of Cerulean Warblers (Setophaga cerulea, a state‑endangered species). The project is part of a long‑term study on Cerulean Warbler annual cycle ecology through the Hardwood Ecosystem Experiment (HEE, (Use the "Apply for this Job" box below).), a 100‑year study of forest management and its impact on flora and fauna.

This is a ~4‑wk position that is expected to run from ~10 May to ~10 June, with some flexibility in start and end dates. The full field crew will be a team of technicians, an MS student (working on an adjacent project), and a post‑doctoral researcher. Free housing will be provided at the Hardwood Ecosystem Experiment Bridge House, a former Girl Scout camp in Nashville, Indiana.

Field housing is communal with bunk beds in shared cabin rooms, shared bathrooms, and shared kitchen space.

Field technicians will help facilitate marking Cerulean Warblers with multi‑sensor geolocators to study migration ecology. Technicians will likely be split into two crews: a larger survey team that will search for and mark warbler locations, and a smaller marking team that directly assists in warbler capture, banding, and tag deployment. The survey crew will search multiple study sites for adult breeding male and female Cerulean Warblers, assess breeding status and mark individual locations with GPS devices.

Survey technicians may gain experience extracting, handling, and banding birds, mist‑netting, tissue sampling, and marking birds with geolocators, depending on work ethic and time availability. The marking crew will assist the post‑doctoral researcher with tag deployment, including mist‑net setup and capture, and, depending on demonstrated skills, help with banding, tissue sampling, and geolocator deployment. Some data entry may be required for all positions.

This position requires early mornings, flexible schedules, strong interpersonal skills, and fieldwork in potentially challenging conditions. Field sites include but are not limited to Morgan‑Monroe State Forest, Yellowwood State Forest, and surrounding areas in south‑central Indiana.

Minimum requirements: All applicants must be able to identify both male and female Cerulean Warblers by sight and sound. Must be willing to work potentially long hours in hot, humid, and rugged terrain (e.g., many steep hills in forests) with timber rattlesnakes and ticks. Must be able to hike and navigate using GPS. Technicians are expected to provide their own binoculars and field clothing.

Must be able to work in both team and individual settings. Must be open‑minded, able to follow detailed directions, and have strong interpersonal skills. Must have a valid US driver’s license.

Preferred experience: Applicants should ideally have some educational experience in ecology, wildlife biology, or adjacent disciplines. Experience independently setting up mist‑nets and extracting songbirds from nets is preferred. Prior experience resighting color‑banded birds, marking birds with color bands, and deploying tracking devices (e.g., geolocators) would be valuable, but is not required. Applicants should have a strong interest in natural history, avian ecology, and field biology.

Please submit a cover letter, resume, and at least two references with contact information as a single PDF document to Silas Fischer at  by 31 January 2026
. Your cover letter and resume should convey your experience and suitability for independent and team‑based fieldwork with birds. If possible, please include at least one reference who can directly speak to your mist‑netting, bird identification, and/or banding experience. Please write “CERW Tech Application – [your last name]” in the subject line.
