The Boreal Chickadee is also called the Brown-capped Chickadee.
Until recent years the Boreal Chickadee was rarely seen far south
of its breeding range, but during several winters it has invaded New
England in considerable numbers and has been found in the lower Hudson
Valley, Long Island, Staten Island and northern New Jersey. At close
range an experienced observer may know the Boreal Chickadee by its dark brown head, while
Brewster states that its "nasal, drawling, tchick, chee-day-day" at
once distinguishes it from the Black-cap. All three chickadee races have been
reported in these winter migrations and only expert examination of
specimens can determine whether the little wanderer is from Labrador,
New Brunswick, or the country west of Hudson Bay.
The Boreal Chickadee is similar to the Black-cap Chickadee and the Carolina Chickadee, but the crown is dark brown.
Population and distribution.
Northern New England and Canada; rarely further south in winter. Represented by three races: the Acadian Brown-capped Chickadee of northern New England, New Brunswick. Nova Scotia and Newfoundland; the Labrador Brown-capped Chickadee of Labrador, and the Hudsonian Brown-capped Chickadee of the region west of Hudson Bay.
The Boreal Chickadee, like other Chickadees, will eat from a feeder, including suet, sunflower seeds, and other seeds and insects.
