Merlin Bird ID
Free bird identification app from Cornell Lab of Ornithology using photo, sound and step-by-step ID
As of 1 September 2026, Merlin Bird ID is free to use. A completely free bird identification app built by a university ornithology lab, with no ads, no in-app purchases and no subscription of any kind. Softwr lists it under Education. Merlin Bird ID is made by Cornell Lab of Ornithology, available on iOS, Android.
Overview
What Merlin Bird ID does
Merlin Bird ID is built by the Cornell Lab of Ornithology, a research unit of Cornell University funded largely by donations and grants rather than commercial revenue. It offers four identification paths: Photo ID from an uploaded picture, Sound ID that listens to a live recording and highlights matching species in real time, a step-by-step questionnaire for someone with no photo or recording, and a regional explorer for browsing likely local species. Regional bird packs can be downloaded for offline use. The fact that distinguishes it from every commercial nature-identification app in this catalogue is the funding model. There is no subscription, no trial that converts to a charge, and no ad-supported free tier with a paywalled upgrade; it is free because Cornell treats it as a public research and outreach tool, not a product line. It also draws its likely-species suggestions from eBird, Cornell Lab of Ornithology own citizen-science database, so its identifications are grounded in real, location-specific sighting frequency rather than a generic model. Buyers are, in effect, nobody, since nothing is sold; the audience is birdwatchers from casual to serious, and Cornell benefits indirectly because identified birds often get logged into eBird, feeding the research database. The trade-off against a commercial app like PictureThis is scope: Merlin only does birds, and its polish in areas like UI refresh speed can lag a well-funded commercial competitor.
What people use it for
- A casual walker who hears a bird and wants to know what it is without paying for an app
- A birdwatcher building a life list who wants identification tied to real regional sighting data
- Someone teaching a child to identify birds without exposing them to ads or a paywall
- A hiker who wants offline bird identification in an area with no signal

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Merlin Bird ID.
- It only identifies birds, so it is not useful for plants, insects or other wildlife the way a general nature app is.
- Sound ID can struggle in noisy environments or with overlapping bird calls, since it depends on a clean audio signal.
- Being a free institutional project, feature releases and interface polish move more slowly than a funded commercial app.
- Photo ID accuracy drops for juvenile birds, moulting birds or poor-quality photos, more so than for well-lit adult specimens.
- It has no social or gamified layer, so users who want streaks, badges or a community feed will find it plain by comparison.
