How a trip works
A trip has its own trail of lessons: meet six species, match them to new photos, then practice with four choices. Species you learn go into your Fieldbook, and starting a trip earns its Passport stamp. Your home place stays as it is.
Species lists and counts from research-grade observations on iNaturalist, as of October 2026. Free, with no ads, no account and no purchases.
