Tools

• search_observations — Search citizen-science observations on iNaturalist. Filter by taxon name (e.g., "Pandion haliaetus" or "osprey"), place name ("California"), year, threatened status, or quality grade. Returns photographed sightings with coordinates, dates, and observer info. Pairs well with GBIF for cross-validation.
• search_taxa — Search iNaturalist taxa by name (common or scientific). Returns taxon ID, rank, ancestry, conservation status, and photo URL. Use the taxon ID for downstream filters or to disambiguate look-alike species.
• top_species — Most-frequently-observed species in a place over a date range. Auto-resolves place name to place_id. Returns ranked species with observation counts and taxonomic info. Great for "what wildlife lives here?" questions.
