Merlin Bird ID is a bird identification app made by the Cornell Lab of Ornithology. It helps you find out what bird you are seeing or hearing. You can use your phone to identify birds with photos, sounds, or a few simple questions.
I tested Merlin Bird ID on a Redmi Android phone for two days. The app was easy to use, and it gave me a fun way to learn more about birds around me.
The app is useful for bird watchers, students, families, and people who simply want to know the name of a bird. It can also help you learn about bird sounds, looks, range, and other details.
How It Compares to Other Apps
Merlin Bird ID is different from apps such as BirdNET and eBird because it focuses on making bird identification simple for new users. BirdNET is mainly known for identifying birds from their sounds, while eBird is better for recording and managing bird sightings. Merlin combines bird identification, photos, sounds, and learning tools in one free app.
Key Tools Explained
- Photo Identification: Merlin can help identify a bird from a picture. You can add a photo from your phone and check the possible bird matches.
- Sound Identification: The app can listen to bird sounds and suggest what bird may be making them. This is useful when you hear a bird but cannot see it clearly.
- Bird Questions: Merlin can ask simple questions about the bird you saw. You can choose its size, color, location, and other details to get possible matches.
- Bird Information: Each bird has useful information and pictures. You can learn about its appearance, sounds, range, and habits.
- Bird Packs: You can download bird packs for different areas. These packs help the app identify birds that are common in a selected region.
Two Days of Testing
I used Merlin Bird ID on my Redmi phone for two days. The app ran well during my test, and I did not face any major problems while opening pages or checking bird information.
The screens moved smoothly when I scrolled through bird lists and photos. I also did not notice serious screen lag during normal use.
There were no major crash bugs during my testing. The phone did not become unusually hot while I used the app for short periods.
Battery drain also seemed normal during my two-day test. Using features such as sound identification can use more battery because the microphone and phone processing stay active, but I did not see a large battery drop during my use.
Memory, Storage, and Safety
The exact download size can change with the app version and Android device. The Play Store listing should be checked for the current download size before installation, as bird packs can also add more storage after installation.
Merlin needs extra space if you download regional bird packs, sounds, and other bird information for offline use. This is useful for people who want to identify birds without using mobile data.
The app may ask for access to features such as the microphone when you use sound identification. Camera or photo access can also be needed when you identify birds from pictures. Location access may be useful for showing birds found in your area.
The Play Store privacy section should be checked before installation because permissions and data practices can change with future app versions.
