Outforia · US Mammal Atlas

Verified US mammal distributions, mapped state by state

Explore established wild mammal distributions alongside open occurrence records showing where animals have been documented. Occurrence points enrich the atlas, but do not by themselves prove a resident population or wildlife range.

Mammals are live now. Birds, reptiles, amphibians, and more are in progress.

  • Occurrence-density maps

    See where animals have been documented without treating every submitted record as an established population.

  • Seasonality & phenology

    Built from observation dates and presented as reporting patterns, not proof of seasonal abundance.

  • ID & lookalikes

    Side-by-side disambiguation of the species that are genuinely easy to confuse.

  • Life-history data

    Longevity, reproduction, diet and activity, sourced and cited, never invented.

Sourced from open, commercially-licensed data: GBIF, iNaturalist and NatureServe.
