Best Bird Identification App

Merlin is the best dedicated birding app. Here is when you might want Spotter instead — or both.

Spotter

Spotter identifies birds alongside plants, mammals, reptiles, insects, fungi, rocks, and more. It lacks sound identification but provides detailed species info across all categories — making it the better choice for naturalists who encounter more than birds on their outings.

Bird Identification Apps

Merlin Bird ID (Cornell Lab of Ornithology) is widely considered the best bird identification app. It identifies birds by photo, sound, and visual description, with full offline species packs and no subscription required. It is exclusively for birds.

Our verdict

For pure birding, Merlin Bird ID is exceptional and hard to beat — especially with sound identification. Many naturalists use both: Merlin for birds and Spotter for everything else they encounter. If you want a single app that handles birds alongside plants, fungi, and wildlife, Spotter covers it all.
