Résumé :	We describe a method for measuring gut passage time and seed dispersal distance for a large terrestrial frugivore. We attached temperature data loggers to radio transmitters in baits that were ingested by free-ranging cassowaries. The resulting data yielded information on how fast the unit passed through the gut (3-4 h) and how far they were moved (240-325 m), an analog for dispersed seeds. Additionally, the data loggers revealed that cassowaries reingest fecal matter, the first observation of coprophagy in wild cassowaries.
