Description

What's that bird? Ask Merlin—the world’s leading app for birds. Just like magic, Merlin Bird ID will help you solve the mystery.

Merlin Bird ID helps you identify birds you see and hear. Merlin is unlike any other bird app—it's powered by eBird, the world’s largest database of bird sightings, sounds, and photos.

Merlin offers four fun ways to identify birds. Answer a few simple questions, upload a photo, record a singing bird, or explore birds in a region.

Whether you’re curious about a bird you’ve seen once or you’re hoping to identify every bird you can find, the answers are waiting for you with this free app from the renowned Cornell Lab of Ornithology.

WHY YOU’LL LOVE MERLIN
• Expert ID tips, range maps, photos, and sounds help you learn about the birds you spot and build birding skills.

MACHINE LEARNING MAGIC
• Powered by Visipedia, Merlin Sound ID and Photo ID uses machine learning to identify birds in photos and sounds. Merlin learns to recognize bird species based on training sets of millions of photos and sounds collected by birders at eBird.org, archived in the Macaulay Library at the Cornell Lab of Ornithology.
• Merlin delivers the most accurate results thanks to experienced birders, who curate and annotate sightings, photos, and sounds, who are the true magic behind Merlin.

AMAZING CONTENT

The Cornell Lab of Ornithology’s mission is to interpret and conserve the Earth’s biological diversity through research, education, and citizen science focused on birds and nature. We are able to offer Merlin for free thanks to the generosity of Cornell Lab members, supporters, and citizen-science contributors.

識別方法が複数あって検索が楽しい。これだというものがヒットすると嬉しくなります。声も複数あって、鳥も個体個体で全てがまったく同じ鳴き方をするわけではないので、比較的これかな?というものを探しやすい。 しかし、図鑑としての鳥の情報がほぼないです。鳥の全長や翼開長などのサイズ、分類(科や目など)、どんな環境にいるか、どんなものを食べるか、などの鳥の情報をもっと増やしてほしいです。そういう使い方をするアプリではないのかな。せっかく検索で見つけられたならその場でその鳥の情報が見れると便利なんだけれど。
