The “rev 0” first prototypes have been re-deployed in seven artificial nest boxes made for macaws in tropical dry forest in Bosque Escondido Costa Rica. The site goes from extremely hot and dry in the dry season to warm and very humid in the wet season, thereby stressing the equipment in two radically different ways. We are running these deployments to learn more about hardware survival in harsh climates as well as interview researchers as they deploy, recover, and work with SD card data. This will give us two field seasons of experience with the same team, to help pinpoint problems in field deployment, even though the data quality of this early prototype is limited.
