Since 2000, citizen scientists have been monitoring populations of montane bird species in the high-elevation forests of the northeastern US through Mountain Birdwatch (MBW), a program administered by the Vermont Center for Ecostudies, eBird’s primary collaborator on Vermont eBird. With 129 routes placed along montane hiking trails throughout the region, there are opportunities for eBirders to contribute data across eastern New York and New England. Thanks to our collaborators at the Vermont Center for Ecostudies for providing this article.
Mountain Birdwatch provides region-wide monitoring for 10 species of birds such as the iconic Bicknell’s Thrush, Blackpoll Warbler, Yellow-bellied Flycatcher, and others that are rarely detected during traditional roadside monitoring schemes like the Breeding Bird Survey. These repeated point-count data will now be made available through eBird each year. Since 2010 alone, several hundred Mountain Birdwatch citizen scientists have conducted 18,636 five-minute point counts at nearly 750 remote locations in the mountains of New York and New England. Recently, the Vermont Center for Ecostudies uploaded more than 37,000 checklists spanning the last 17 years of the program. [Team eBird note: learn how to upload your spreadsheet data here.]
Mountain Birdwatch routes consist of ~6 sampling stations located along hiking trails in the montane spruce-fir forest, generally above 2,600 feet elevation. Observers choose any morning in June with fair weather to complete their surveys. The simple protocol and short list of monitored species means that almost any birder who likes to hike can participate. The results provide powerful insight into the health of our montane bird populations in the northeastern U.S.
For example, using MBW data, we recently published a population estimate for Bicknell’s Thrush in the U.S. (~71,000), and identified that the White Mountain National Forest likely harbors nearly one-third of the entire U.S. population of Bicknell’s Thrush—one of the most range-restricted bird species in North America. With these data, we also created a fine-scale (<1-hectare) online abundance map predicting the population size of Bicknell’s Thrush across all lands in New York and New England.
Interested in contributing? We still have routes available to survey this June across New York and New England. You can learn more about the Mountain Birdwatch program, see a map of available routes, and find out the status and population trends of monitored bird species by visiting our State of the Mountain Birds website.
