One thing we’ve realized as we talk to people about Merlin is that a lot of people use it for one main function, but may not be aware of other great features just a few taps away, including a full set of bird songs, automatic identification of birds in photos, ways to interface with eBird lists, and much more. Here, we've compiled some features that can boost your birding even more.


Quick Links


Listen To Songs And Calls

Merlin doubles as a set of bird songs and calls you can use as a reference when you’re outside. If you hear something you don’t recognize, use the Explore Birds feature to search or browse through the species in your app. Tap on a species to open up a list of recordings of the species’ most common sounds.


Improve your Smartphone Photography to ID Birds

If you can get a photo of a bird on your smartphone, you can use Merlin to identify it. The photo doesn’t need to be great, either—Merlin’s image recognition can probably handle it. Even if you can't get a good enough photo with just your smartphone, you can even take a photo of a photo, take a photo through binoculars or a spotting scope, or take a snapshot of the back of a camera.


Set Your Location So You Can ID Birds Even Without Internet

Merlin is designed to help you identify birds no matter how deep into the forest or field you are. This is important when you are traveling off the beaten path, or even if you have spotty Internet around your hometown. You don’t want to be stuck not knowing what bird you are looking at just because you can’t connect!


The key to using Merlin Bird ID when you’re offline is to set your location ahead of time. Tap on Explore Birds, then look for the filter icon in the top right of your screen. Tapping this will open up a panel where you can set your location to whatever your destination is. When you are off adventuring, those locations you set will be available in the history of locations, and will work completely offline.


Get A Custom List Of Birds For Any Location

Sometimes you don’t want to use Merlin Bird ID to identify birds one by one, you just want a list of which birds are most likely in an area. Use Explore Birds to do this. With Explore Birds open, tap on the filter icon in the upper right, tap filter by Likely Birds, and then choose your location and date. Merlin will build a custom list of birds for your location so you can focus on learning just the birds you’re likely to see.


Bonus tip: With the filter panel open, set the Sort order to Most Likely. Instead of viewing birds alphabetically or taxonomically, you’ll have a nicely ordered list of birds from most common to least common. Scan that list to figure out which birds to focus on first.


Share Your Birding Finds

Whether you've found your Bird of the Day or are celebrating a new life bird, share your birding discoveries with friends and family. Tap on the sharing icon (square with an arrow) in the lower right hand corner of your “Your Bird of the Day” image to bring up sharing options. Tap on the “Explore” and “Life List” tabs to view additional species you can share. Sharing is compatible with text, WhatsApp, and social media platforms.


Get Jazzed About Your Vacation

As a bird watcher, one of the side benefits of any travel is the opportunity to see new birds. You can download Merlin bird packs for popular vacation spots like Hawaii, the Caribbean, Central America, Europe, and every other region of the world.


Bonus tip: Set Explore Birds to your vacation destination, and sort by Most Likely (see previous section). This will give you the list of species that you are most likely to jump off the plane and see. Study these, and you’ll feel right at home.


Find Birds You’ve Never Seen Before

On Explore Birds, you can hide the birds already on your life list—this creates a customized list of target species for any location in the world. These custom lists make for great study tools and help you know what to expect when you are out birding.


Find Out When Birds Are Passing Through

Once you’ve set your location in Explore Birds (see “Set Your Location,” above), the app will display eBird bar charts for each species that let you know how common the bird is in your location throughout the calendar year. It even helpfully adds a dark line to show you the current date. With a quick glance, you can see which birds are around in which season, and get extra detail about precisely when migrant species are likely to be passing through. Glance through the list to refresh your memory on which birds to expect in the coming weeks and you’ll be super prepared for your next birding excursion.


See Regional Variations In Bird Plumages

Lots of bird species look different from place to place across their range—common examples include Song Sparrows, Red-tailed Hawks, and Dark-eyed Juncos. Merlin’s photo galleries have you covered for all this variation, in addition to showing what males, females, and immature birds look like for each species.
