Why look for an alternative?
Merlin, from the Cornell Lab of Ornithology, is excellent and free. People still look for alternatives because they want one or more of these:
- A simpler setup without downloading regional "bird packs."
- Both sound and photo ID in a cleaner, faster interface.
- A richer in-app field guide with deeper species profiles.
- A second opinion — running two apps on the same bird boosts confidence.

Try BirdNote — a free Merlin alternative
Sound ID, photo ID and a 10,000-species guide, no regional packs to download.
The 5 alternatives
1. BirdNote — best all-round free alternative
BirdNote pairs a fast bird-song identifier with a photo identifier and a deep guide to 10,000+ species. Every result includes a confidence score and a full profile. It works out of the box without downloading regional packs, which makes it a refreshingly simple alternative for casual and travelling birders.
2. BirdNET — best sound-only alternative
Also from the Cornell Lab (with Chemnitz University of Technology), BirdNET is a research-grade, sound-only identifier. It's free and accurate, but doesn't do photo ID — pair it with a photo app if you need both.
3. Picture Bird — most beginner-friendly
Picture Bird leads with photo ID and adds sound. It's polished and easy, but several features sit behind a subscription, so it's best if you prefer a guided experience and don't mind paying.
4. Song Sleuth — best for studying songs
Song Sleuth focuses on visualising and analysing bird songs with spectrograms. It's a paid, sound-only app aimed at birders who want to study calls in detail rather than just get a quick name.
5. eBird — best companion app
Also from the Cornell Lab, eBird isn't an identifier but is the gold standard for logging sightings and seeing which species are near you right now — which is invaluable context for confirming any ID.
Which should you pick?
- Want sound + photo in one simple free app? Try BirdNote.
- Only need sound, prize accuracy? BirdNET.
- Prefer a guided, photo-first experience? Picture Bird.
- Studying songs seriously? Song Sleuth.
- Want to log and track sightings? Pair any of the above with eBird.
