Sharply cold air flooded my lungs when I stepped outside
this morning. A fresh dusting of snow glittered where the morning sun filtered
through trees, and that same sun shone on rosy clouds in a blue sky. I took
another breath. Inhale beauty. Exhale gratitude.
Crunch…crunch…crunch. With sunflower seeds cupped in my
outstretched palm, I walked to a spot in between the thicket of balsam fir
trees and the empty bird feeder. The trees were silent – frozen by my movement.
The hyperactive hopping of a single chickadee broke the stillness. Within
seconds, the whole flock was back.
During the summer, black-capped chickadees focus on their
mate and their chicks. Even if I didn’t have to take my feeder down because of
the bears, they would not gather like this for a group feast. By late fall,
chickadee flocks are well established and ready to defend a winter feeding
territory. One territory just happens to include my feeder.
Like wolf packs, chickadee flocks have alpha and beta
pairs at the top of the hierarchy, other mated pairs below them, and then
unmated juveniles at the bottom. Unlike wolves, the juveniles are not the
offspring of pairs in the flock. Instead, their parents kicked them out of
their childhood range in the hopes of spreading genetic diversity a little
wider.
As I stood there, hand outstretched, I listened to the
interactions of the flock. Dominant birds responded with aggressive gargles
aimed at lower-ranked birds who got too close, or disputed the ownership of a
seed. Researchers have found that the gargler almost always wins the fight. Shy
“tseet tseets,” from hidden chickadees maintaining contact with the flock
filtered through the thick boughs. Chickadee-dee-dee calls could have been
greetings to friends, or warnings about the possible danger of my presence.
The whirr of wing beats also filled the air as chickadees
swooped bravely over my head to the empty feeder, then on to perch on the broom
handle near the door, to cling to the side of the porch pillar with needle-like
toes, and then back to the safety of the fir boughs. None flew to my
seed-filled hand, although I hoped very intently.
Why wouldn’t they jump at the chance to eat a few more
seeds? In order to maintain their normal 108-degree body temperature,
chickadees must eat the caloric equivalent of 250 sunflower seeds each day.
They gain up to ten percent of their body weight in fat each day, and burn it
off each night to stay warm.
Maybe the chickadees weren’t hungry enough to brave my
hand because they were raiding their cached food instead. Norwegian researchers
found that the tit, (a chickadee relative,) caches up to 80,000 seeds in a
single autumn. Unlike red squirrels, who put all their seeds in one stump and
then have to defend them fiercely, chickadees spread out their seeds singly,
and don’t worry about a few getting stolen.
If I were a chickadee, my biggest source of seed loss
would be my own forgetfulness! Chickadees have it figured out. They use
forgetfulness to make space for new memories each year. Each fall, brain
neurons containing old information die, and new neurons grow with current
information about seed locations, social flocks, and their habitat.
This also means that they have forgotten my past role as
a harmless provider of food. My hand throbbed with cold, so I stuck it back in
my mitten and walked down to the lake for a break. Those rosy clouds and that
blue sky sat reflected in a section of open water, surrounded by a skim of ice.
I continued down the driveway, stepping over the leaping
tracks of red squirrels, the tiny bounds of mice, and the snowed-in trail of a
midnight fox. All these brave creatures share the winter world with the
chickadees and me.
Scooping seeds out from the tip of my mitten where I had
stored them, I tried again. Standing silently, hand outstretched, I waited.
Again, the flock began swooping around me, but not landing. Then a different
movement caught my eye – a vole was foraging at the base of the dead spruce.
The instant that my focus left the chickadees for the
vole, I felt the spiny grip of a chickadee on my finger. Not daring to shift my
gaze and scare it off, I kept my eye on the vole, and my awareness in that
finger. I took a deep breath of crisp air. Inhale beauty. Exhale gratitude.
Now the spell was broken. Several more chickadees swooped
down to grab seeds. In between, I was able to look down. One chickadee cocked
its head and peered up at me through a shiny black eye, as if to say, “I see
you. You’re ok.” That was all I wanted.
“Sometimes I need
only to stand wherever I am to be blessed.”
