We developed and evaluated a surgical procedure for implanting radio transmitters in 1-d-old Canvasback (Aythya valisineria) ducklings. Transmitters (1.5 g) were implanted subcutaneously on the back of ducklings while under a general anesthetic, isoflurane, within a few hours of hatching. Evaluations indicate that the procedure is a reliable method for radio-marking ducklings.
