snow storms 2014

Snow Birding

We are hunkered down here in the midwest, heeding weather forecasters who predict another barrage of snow on top of the storm that ushered in 2014 earlier this week. But it was sunny and bright during the early part of the day, and we walked down our frozen street wearing the unlikely combination of sunglasses and earmuffs. Between the holidays and two big snowstorms back to back, I’ve found myself with a totally unprecedented amount of quiet time. Is there anything I like better than quiet time?

Not much.

Of course I can always find ways to keep busy. I’m surrounded by books, I have hundreds of movies and TV shows at my disposal (thank you, Netflix, Amazon, and TiVo). I always have the Book Project to fall back on should I find myself bored. (ha!)

My interest in birds is a new one, and because there are so many birders in our neighborhood who feed and water them regularly, there is a large assortment always available for observation.

A friend sent me an interesting article about chickadees - apparently their little birdbrains physically expand by 30 % every winter to accommodate memory storage of all the places they’ve hidden gathered seeds during the fall. When spring comes, their brains “shrink” back to normal size. "They grow more brain when they need to remember things; then shrink that brain when the "remembering" season ends."

As recently as 1994, scientists did not believe this was possible - in birdbrains, let alone in human brains. But guess what? Homo sapien brains can expand too. Every time we learn something new, we grow brain cells.

Learn enough, and the concept of big-headedness will be more than metaphorical.

That’s kind of comforting, isn’t it? Especially when you’ve reached the age where recalling the spot you left your coffee mug, book, and reading glasses can lead you on an hour long wild goose chase through the house.

So yes, bird (and presumably all mammals) can grow brain mass and power. But it’s the second part of that sentence which really caught my attention.

That their brain shrinks when the remembering season ends.

Sometimes it seems like old age marks the end of the remembering season. Especially when folks become infirm and  have to move out of their homes and into care giving environments. Although they might provide “memory-stimulating” activities, it seems like they're really just false approximations of the real-life events our brains are designed to work with.

Even at my stage of life, I can sometimes feel my brain stultifying (especially after too many hours on Facebook!) I really want to stay firmly rooted in the remembering season. That’s another reason why I love reading, writing, and playing music  - those activities are the nuts and seeds I gather all year round, expanding my brain cells with every page written and read, every note played.
