Boreal Chickadee
Poecile hudsonicus
'Boreal' is for the northern spruce forests it lives in, and goes back to Boreas, the Greek god of the north wind. Like other chickadees it says its own name, but in a husky 'tsee-day-day.'
Poecile comes from the Greek poikilos, 'multicolored'; hudsonicus means 'of Hudson Bay.'
