I don’t know if we think about it, but we do have a wonderful selection of Chickadees here in North America. On my list is the Black-capped Chickadee, Carolina Chickadee, Chestnut-backed Chickadee and Mountain Chickadee. Add to that Grey-headed Chickadees and Boreal Chickadee and the Mexican Chickadee.
These tits are tough as nails. I’ve seen Black-capped chickadees and Mountain Chickadees survive sub-zero weather…-20F.
When you consider that they weigh about the same as a bill from the IRS, that is something to ponder.
One behavior that I observed this year that I’ve never seen before is this Black-capped Chickadee foraging on this fungus. I saw it twice on two different occasions.
