With nearly two decades of monitoring data, Mountain Birdwatch is helping biologists, land managers, and policy makers make sound songbird conservation decisions. Mountain Birdwatch is also integral to the ongoing efforts of the International Bicknell’s Thrush Conservation Group; since Mountain Birdwatch is the best source of information about Bicknell’s Thrush in the United States, our data serve as the main tool to evaluate progress towards the group’s goals.

The State of Mountain Birds, a new report by VCE, documents the health of these mountain forest songbird populations. Although species like Black-capped Chickadee and Swainson’s Thrush have thrived in the mountains during recent decades, some species that depend on the region’s evergreen forests of spruce and fir – notably Blackpoll Warbler – appear to have undergone substantial declines.


We’re continually analyzing these data to help us in understanding how songbird populations are changing in our mountains. We welcome data requests and requests for collaboration.  The following data are available as open data:
