During these cold snowy days, I find it especially pleasant to be reminded of verdant mountain summers—by feathered friends. Here in western Massachusetts, flocks of dark-eyed juncos are common visitors to birdfeeders in winter. By late April, however, they will disperse to their breeding grounds in coniferous or mixed-coniferous forests in the U.S. and Canada. On the highest summits of New England and New York, hardy juncos are one of only a few species to nest in the alpine zone above treeline.
On their July 1902 hike, Hattie Freeman and Emma Cummings met them all along the Presidential Range. “Occasionally we paused to listen to some bird note,” Hattie wrote. “We knew the Swainson’s thrush, winter wren, blackpoll warbler, black-throated blue warbler, junco and 
Peabody birds.” Emma Cummings included all of these mountain species in her 1904 guide Baby Pathfinder to the Birds.
Schuyler Mathews, author of the 1904 Field Book of Wild Birds and Their Music, observed juncos on Mt. Washington and described their song as a “metallic or glass-like tinkle.” Dr. Nancy G. Slack, my co-author for Field Guide to the New England Alpine Summits (2014) likens it to “a musical sewing machine.”

In 1885, ornithologist Bradford Torrey spotted “the prettiest [junco’s] nest . . . beside the Crawford Bridle Path, on Mount Clinton. It was lined with hair-moss . . . and with four or five white, lilac-spotted eggs made so attractive a picture.”
At summer’s end, juncos reverse their migration. Florence Merriam, in Birds Through an Opera Glass (1889), welcomed the autumn juncos as “companies of little gray-robed monks and nuns, just emerging from the forests where they cloister during the summer months.” It’s an imaginative description—visually apt, but technically incorrect. Juncos might be reclusive, but they are not celibate. They spend May-July mating and raising their young.
I’ll admire my juncos while they brave this week’s polar-style weather. And I’ll look forward to catching up with them in the north woods this summer.
