About
The Team
The people who record, annotate and listen, in Yellowstone and around the world.
The Cry Wolf Project was started by Dr. Jeffrey Reed and Dr. Dan Stahler of Yellowstone’s Wolf Project to build the largest database of wild wolf vocalizations in the world.
Yellowstone’s Wolf Project is run by the National Park Service and studies the wolves of Yellowstone National Park. Jeff is an associate researcher with the Wolf Project, supporting Dan’s team with technology. The Cry Wolf Project draws on the Wolf Project’s data and on recordings from partners around the world, scientists and citizen scientists alike, to add depth to the database across more places and more years.
Together we have recorded over 600,000 hours of raw sound in different locations, and gather about 300,000 hours a year. From those recordings we annotate every type of wolf vocalization, and we develop AI to speed up that work.

The Yellowstone Wolf Project is recognized internationally as the premier long-term study of wolves and their ecosystem impacts. For decades, it has provided invaluable data on wolf behavior, ecology, and their transformative role in the Yellowstone ecosystem. From wolf social behavior to multi-species interactions, the project continually expands our knowledge of complex natural systems through ground-breaking research, monitoring, and conservation outreach. This cutting-edge study on wolf communication is the next part of our legacy of discovery.
With gratitude
None of this happens without the Yellowstone Wolf Project.
The Cry Wolf Project stands on decades of fieldwork by the Wolf Project’s scientists: the observations, family trees and collared wolves that give every recording its meaning. Researchers and citizen scientists around the world add their recordings, annotations and time.
