What is real here

Every photograph and every outline comes from a real, openly licensed image, credited at the bottom of its card. Only plain charts are drawn.

The words on these cards are written by AI from the sources named on each card. Software matched every number and claim to a sentence in those sources. Mistakes are still possible, so follow a card's links before relying on it.

Globe dots are real recorded sightings from GBIF. Where a card says native range only, they are clipped to that range. Otherwise they can include zoos, gardens and places the species was introduced.
