Merlin now offers free downloadable packs for North America, Central America, the Caribbean, Colombia, Brazil, and Chile, as well as Europe and common birds of India. You can download the packs you want, and delete them to free up your phone storage when you no longer need them. In addition to more than 3,000 bird species to explore in the app, Merlin can now identify a bird from a photo you take with Photo ID, helps you find new birds with the Most Likely feature, and has integrated the eBird Life List for eBird users.

Today we’re launching Merlin Bird ID, a free app to help beginners identify birds. When designing it we asked, What if an app could quickly tell you which birds are most likely based on your location, date, and a brief description? Not just which birds theoretically could occur near you, but which birds are actually reported most often by other birders. That’s what Merlin Bird ID does. Watch the video (above) for more on how it works—and please share it via Facebook, Twitter, or email with anyone you know who’s interested in birds.
Merlin Bird ID covers 285 of the most common birds of North America (with more on the way). In addition to help with ID, it contains expert tips, more than 1,400 gorgeous photos, and sounds for each species. It’s available now for iPhone and other iOS7 devices, and it’s coming in spring 2014 for Android.
