Black-capped chickadees are a beloved fixture at the Arboretum, one of our common year-round residents and the state bird of Massachusetts. Visitors can easily observe them flitting through the branches, often in small groups during fall and winter and in pairs during spring and summer.
In Boston, black-capped chickadees begin searching for nest cavities around mid-March, weeks before most migrant species return. By mid-April most are building nests and by the first week of May the females typically are laying eggs. The nestlings begin hatching two weeks later, grow rapidly, and start fledging in early June.
Each year, the Arboretum’s NestWatch volunteers follow this process by monitoring over a dozen “chickadee tubes” installed throughout the landscape. These nest tubes are variations on a design by Dr. Desiree Narango and are specifically designed to attract and accommodate chickadees. The following photos depict the life stages of young black-capped chickadees in several different nest tubes throughout the grounds.
Juvenile chickadees face long odds. Although the average lifespan of a black-capped chickadee in the wild is about 2 years, it is likely that most of this year’s fledglings will not survive the next few months. However, if they learn quickly to avoid predators, survive disease, and find enough food to live through the hard winter months to come, we may see these same birds again next spring. They will be looking for mates (and nesting sites) to start the process all over again.
From “free” to “friend”…
Established in 1911 as the Bulletin of Popular Information, Arnoldia has long been a definitive forum for conversations about temperate woody plants and their landscapes. In 2022, we rolled out a new vision for the magazine as a vigorous forum for tales of plant exploration, behind-the-scenes glimpses of botanical research, and deep dives into the history of gardens, landscapes, and science. The new Arnoldia includes poetry, visual art, and literary essays, following the human imagination wherever it entangles with trees.
It takes resources to gather and nurture these new voices, and we depend on the support of our member-subscribers to make it possible. But membership means more: by becoming a member of the Arnold Arboretum, you help to keep our collection vibrant and our research and educational mission active. Through the pages of Arnoldia, you can take part in the life of this free-to-all landscape whether you live next door or an ocean away.
