Winter sent its warning through the northern woods.
The geese heard it and flew south. The turtles heard it and sank into the mud at the bottoms of their ponds. The chipmunks heard it and vanished into deep burrows with their cheeks packed full of seeds.
And a small brown frog with a dark mask across his eyes sat down in the fallen leaves and stayed exactly where he was.
A squirrel paused on a branch above him. "Frost tonight," she said. "You should dig."
"I am staying right here."
"Then swim. The pond bottom is very popular."
"I am staying right here."
The squirrel flicked her tail. "So what, exactly, is your plan?"
The wood frog snuggled deeper into the leaf blanket.
"I am going to stop," he said.
That night the frost came creeping, and the frog began the strangest sleep in the northern forest.
As the cold touched his skin, his body flooded itself with sugar, sweet as syrup, and the sugar wrapped his cells like tiny blankets. Ice crept through him anyway. It froze the water just under his skin. It froze more than half of the water in his body.
His breathing slowed, then stopped.
His heartbeat softened, and softened.
Then it stopped too.
Nothing moved.
Snow settled over the leaves, and the leaves lay over the frog, and the frog lay still as a pebble, a frog-shaped piece of winter with a secret sweetness inside.
He did not dream. He did not shiver. He waited the way seeds wait.
Wood frogs live farther north than any other frog in North America, even beyond the Arctic Circle, and up there the waiting can last for months. He was built for every one of those cold, quiet days.
Then came a drippy morning when the sun leaned closer. Meltwater trickled through the leaves. And deep inside the still little body, something flickered.
A heartbeat.
Another. Then a steady drum.
His lungs filled. His legs twitched. His eyes blinked open, and the wood frog sat up in a puddle of brand-new spring.
He had somewhere to be.
Snowmelt had filled the shallow woodland pools, and the year's first frog chorus was already tuning up, a chorus that sounds exactly like a pond full of quacking ducks. He hopped toward the sound, thawed and loud and gloriously alive.
The squirrel stared as he passed. "You stopped," she said. "I saw you. You were ice."
"I was," said the frog. "And now I am music."
Spring always finds the patient.
Some hearts simply know how to wait for it, still and trusting under the snow, holding their song until the world is warm enough to hear it.
