This was the highlight of my Memorial Day weekend.
A couple of people told me about this phone app, which ingeniously identifies birds by listening to their calls and whatever sounds they make. It shows you the sound patterns it's picking up, indicates when it detects a bird, and then adds the identified bird to the list. Every time it detects more sounds from the same bird, it highlights that line in yellow.
It has detailed info about any bird you've identified.
And it has a bunch of pre-recorded clips of all the calls and songs the bird makes, so you can compare it to what you're hearing.
When I first heard about it, I said it sounds like Shazam for birds. And that's exactly what it is. I found myself taking the phone to the marsh/pond on our street, so I could identify the ducks and geese that hang around there. There's something addicting about it.
After downloading the app (and giving Cornell Lab your email address), you have to download a bird packet. I got the Northeast US packet, which has 685 birds in it. I guess this is what seems exciting to an older guy.
