Résumé :	We modified a figure-8 leg-loop harness designed for small passerines to attach successfully 1.8-g radio transmitters over the synsacrum of migrant Soras (Porzana carolina). Because of the short caudal region of Soras, addition of a waist loop was critical to securing the transmitter while leg loops were maintained to center the package. Thin gauge (0.6-mm diameter) elastic thread proved ideal for transmitter attachment and allowed for freedom of movement and girth expansion associated with fattening during a 6-10-wk stopover. Of 110 Soras radio tagged during three field seasons, only a single mortality was observed and only a single bird last its transmitter. Migration from the study area was confirmed for 76 (69%) and suspected for another 25 birds (total 92%).
