Frozen Kingdom

Recently, freezing rain shocked our south Louisiana sensibilities. As I sat warm in my living room, I watched some brown finches duck under a leafy green bush near the porch to escape the icy drizzle. While I pondered the small birds plight, white accumulated on the wood planks of our wharf. Mist rose from the chilled river in buffs that scurried across the ripples from the North Wind's breath.
Twice in sunny weather, I've spotted a bald eagle taking flight from the trees on the far bank. It prompted me to write this poem:

Frozen Kingdom

Where is the eagle?
Where does he roost in an unlikely storm?
The sparrow hops beneath the evergreen,
but not his majesty.
No cover for the king, whose wings require space.
Free to rise above his realm—
glide the frozen pathways of the wind.

Around 10am, hoping to glean some warmth through osmosis and a familiar laugh, I called my aunt in Phoenix. As we spoke I looked out the window and perched on a dead pine, 150 feet in the air sat my eagle. I ran to get the binoculars. This is my third sighting and the first time I've seen him perched. His backside towards me, he glance over his shoulder to reveal that magestic white head and hooked beak, and I saw his eye close. From this direction, I'm not sure if he was blinking or if that was a wink, but with that he took wing and was gone.
What a writing prompt—what motivates you?
