Empowering communities with real, actionable science.

Listen together. Count for something.

Every Terra Station documents the birds and wildlife at your station around the clock, and its detections feed a continental dataset open to researchers and conservationists.

  • Made by Cellular Tracking Technologies, Cape May, NJ
  • Wildlife-tracking hardware for researchers since 2009
  • 2,500+ stations deployed
  • Motus-compatible radio-tag detection
  • Volume and education pricing
  • 30-day returns

Building a network, one location at a time

You don't need a science degree to contribute to research. A station that is up and listening is already doing the work automatically: logging migration and population data at a scale no human survey can match.

  • ✓ Zero-effort data collection
  • ✓ Every station expands the Motus radio-tag network — helping track tagged birds, bats, and insects
  • ✓ Contribute to conservation in a concrete way

Project Monarch

Groundbreaking Monarch Butterfly Data — Terra is There

In 2025, Monarch butterflies released at Cape May Point carried tiny BlūMorpho radio tags across the US and into Mexico. Every Terra Station has a compatible antenna, so as the butterflies moved south, stations in ordinary backyards logged them along the route. The track made the front page of the New York Times.

More than 400 monarchs carried tags in fall 2025, with more each season, and the project is still running. If your station is up and listening, it's already part of it.

Better Together

One station is a data point. A handful, spread across a town or a watershed, is a network. $329 each, with group pricing for 3 or more stations.

Conservation starts with data. In the past that meant professional, long-term surveys. Terra automates that process and arms you with the data you need to defend and preserve your local wild spaces.

Bird clubs

Bring members together to learn more about your area or research a specific question.

Neighborhoods & towns

Protect your wild spaces with real data. A continuous record of the species on a site supports petitions and applications to conserve it, including those made under the Endangered Species Act.

Watershed & conservation groups

Survey your property for every type of wildlife, and document the effects of conservation projects.

How a group project works

Three steps from one station to a shared survey

Step 1

Create a group

Each member or site gets a Terra. Plug it in, scan the QR code, and it is listening the same night. Then share the Terra with your group, and all the members will be able to see the stations.

Step 2

Make them public

Share a station online with the Terra widget, which streams your project directly from your website so the public can learn more or join your project.

Step 3

Build your case

Gather the data you need for your project and take action.

Become a force for change

Data from Terra projects can be used for reports, newsletters, town meetings or government applications. You'll have a consistent, thorough record of your survey.
