The Mountain Chickadee is the only chickadee with a white supercilium, a bold streak above the eye that distinguishes it from the Black-capped Chickadee. It is the quintessential bird of western mountain conifers, often the first bird to find and mob a visiting birder. It caches seeds in thousands of locations and has a proportionally large hippocampus — the brain region linked to spatial memory.
