About Terra

A Terra Station sits outside and listens 24/7. It identifies the birds it hears and sends them to a free app. The apps also carry live global feeds from around the world, including Colombia, the Galápagos and the Pacific Northwest. Terra is for birders, teachers, land managers and anyone who wants to connect, learn or conserve wildlife. The free Terra app is rated 4.5 stars on the App Store.

Terra detects radio tags, so a station in a backyard can pick up a tagged bird, bat or butterfly passing overhead and add that record to the tracking networks scientists already use. Identifications and tag detections from the whole network flow into one database that researchers can draw on. Combined, Terra Stations create a powerful network for community science. Terra is made by Cellular Tracking Technologies in Cape May, New Jersey, a team that has built wildlife-tracking hardware for researchers for more than a decade; the first Terra Stations shipped in 2024, and more than 2,500 units have been delivered.

Scott Whittle

Scott Whittle is a birder, photographer and co-author of The Warbler Guide, and he lives in Cape May, New Jersey — one of the best places in the world to watch migration. He spent years teaching people how to identify birds by ear before helping start Terra. The idea was straightforward: let anyone hear the wildlife around them, and let that listening count for something.

Contact him at press@terralistens.com for information or help. He's happy to arrange a loaner station, a demo, or a walk-through of the live map.
