About

A Bird A Day

Read full description

A Bird A Day is a collecting app. For birds. Every day, a new bird appears: beautifully illustrated, named, and paired with its scientific name, real song, and a short fact you will probably end up reading out loud. Each bird joins your flock, and your collection grows one day at a time. Rearrange your birds, revisit old favorites, and watch your flock slowly become its own thing. --- Everyone's collecting the same birds. Yet, you don't know which one shows up tomorrow. You don't know how many there are and your flock isn't like anyone else's. You might meet a Pileated Woodpecker on day 3. Your friend might not see one until October.
