Read full description

Identify birds, animals, plants, bugs and mushrooms from a photo. Identify birds, frogs, insects and mammals by their calls. Then ask why. KAGN is an AI wildlife identifier and field guide that does not stop at the name: it notices what is interesting about the cardinal or the monarch on the milkweed, and suggests the questions to ask. Snap a photo and KAGN names the species, with the field marks that decided it. Then it points at what you might have missed, with suggested questions one tap away: a slit on a cicada's back becomes the question you would never have thought of. An identification is where other apps finish. It is where KAGN starts. Discover Nature's Secrets Keep asking. Why is the bee working that flower? Does this red-tailed hawk look injured? Why is the black bear out in daylight? Your own photo stays in context, so every answer is about the animal in front of you, not a generic species page: behavior, habitat, diet, migration, look-alikes. Bird Song Identifier and Bird Call Identifier Hear a warbler high in the oaks but cannot see it? Record it and the bird sound identifier names the bird from its call or song. It names birds, frogs, insects and mammals too, from the spring peeper to the katydid. It is free to start, and it runs on your phone, so the dawn chorus is no longer a mystery. Bird Identification From a Photo Bird identification for North American birders, from the backyard feeder to the flyway. A bird guide and bird scanner in one: photograph the cardinal and get the species, a confidence score, the alternatives worth ruling out and the field marks that separate them. Animal Identifier, Snake Identifier, Bug Identifier and Mushroom Identifier One AI species identifier for mammals, reptiles, amphibians, insects, spiders, fish, trees, flowers, weeds and fungi. A frog identifier for the spring peeper by the pond, a spider identifier for the orb weaver in the shed, a butterfly and caterpillar identifier for the monarch, a plant identifier for the black-eyed Susan and a weed identifier for the lawn. Identify animals from the black bear to the garter snake. AI That Teaches You the Field Marks KAGN shows you why. Every result highlights the colors and markings, shape, bill, wing, leaf, petal, bark or body structure that identify the species, so you learn to recognize the cardinal yourself. Ask Anything About Any Species Chat with the AI naturalist about any species in the field guide. Where it lives, what it eats, how rare it is, when to see it. A wildlife guide in your pocket for your backyard, a state park or the trail. Your Wildlife Journal, Bird Journal and Life List Save sightings with photos, sound recordings, video, notes and location. Build your life list and keep trip lists. Your sightings stay on your device unless you back them up, and you can export them at any time. Explore Community Sightings See what others are spotting: search sightings by species and explore what is being seen near you on a map. Plan Your Next Trip Heading to Yellowstone? Ask KAGN what is there and get the species to expect. Scout uses your life list and recent sightings to suggest the target species for your next lifer. Packs for Everywhere Regional packs for North America: North American Birds, Mammals, Reptiles, Plants and Insects, with the same packs for the Caribbean, Central America, Europe and every other region. Worldwide packs cover every group. Every pack is included. Free to Start KAGN is free to download and free to start. Upgrade options and prices are shown in the app in your local currency.
