The Bird Who Had Never Been South

The swift had been alone on the wire since morning.

"Its whole family left," Maya said. "Days ago. Mr. Okafor said the flock went last week."

Soren tipped his head back. The bird was small against the orange sky, a dark hook of a thing. "So it got left."

"It didn't get left. It hatched this summer. It's never even done this before."

"Done what?"

"Gone south. Africa. Wherever swifts go." Maya pulled her knees up on the back step. "It's never been there. Nobody's taking it. So how does it know which way?"

Soren thought about that. "Maybe it follows the others."

"There are no others. That's the whole point. They're gone. It's by itself."

They watched it. The swift adjusted its grip on the wire and looked, as far as they could tell, at nothing.

"Okay," Soren said. "Suppose I had to walk to a city I'd never seen. I'd follow the road signs."

"It can't read."

"Landmarks, then. Rivers. The coast."

"It's never seen the coast either. It came out of a nest in Mr. Okafor's chimney and it's been eating bugs over our street its entire life." Maya pointed up. "That's its whole map. Our street."

Soren went quiet. Then: "The sun's setting over there."

"So?"

"So it knows where west is. If it watches the sun every day it knows the sun moves. That gives it a direction."

Maya turned this over. "At night the sun's gone, though."

"Stars. There's a point the stars turn around. The still one." Soren had watched that once, six nights of it, a camera pointed up while he slept beside it. The stars wheeled and one barely moved. "If you find the still point, you find north. Even a bird could learn that by watching the sky spin."

"It can't see stars in the daytime."

"Then it uses the sun in the day and the stars at night."

Maya was already shaking her head, not to say no, but the way she did when a thing was bigger than the answer. "What about cloudy nights. No stars. No sun. Then what."

The swift launched suddenly, flicked twice over the rooftops, and came back to the same spot on the wire. Practicing, maybe. Or just being a swift.

"Then it needs something it can feel," Soren said slowly, "that's there whether it's cloudy or not."

"Like what's everywhere."

They looked at each other.

"The magnet thing," Maya said. "The Earth one. The compass."

"Birds can feel it. I read it. Something in their eyes, maybe, so they sort of see it." Soren stopped. "That's weird. That's actually weird. It might be looking at the magnetic field right now. Like a color we don't have."

Maya didn't say anything for a second. The idea of a color she didn't have sat on her like a cold coin.

"So it has the sun," she said. "And the stars. And the magnet field it can maybe see. That's three."

"Three different ways to find south," Soren said, "and it's never used any of them for real, not once, and tonight it's going to use all three to fly to a continent it has never been to."

They sat with that. Down the street a dog barked and gave up.

"There's more," Maya said suddenly.

"More than three?"

"Smell. I'm sure I read birds smell their way. Different places smell like different things, and they build a map out of smells." She frowned. "And there was something else. A sound thing. Sounds too low for us. From the sea, or mountains. They hear it from really far."

"Infrasound," Soren said. The word felt good to say. "Waves crashing make it. Wind over mountains. It travels for hundreds of miles and we can't hear any of it."

Maya looked up at the one small bird, then out past the rooftops where the orange was going purple.

"So right now," she said, "it's standing on a wire over our boring street, and it's feeling the magnet field, and it remembers where the sun went down, and in a couple hours it'll read the stars turning, and it can smell places it's never smelled, and it can hear the ocean we can't hear." She breathed. "It's standing in the middle of like five maps at once."

"And it doesn't need any of us," Soren said. "Nobody taught it. There's no flock. The whole route is already inside it, and it's only ever flown over one street."

Maya pulled her sleeves over her hands. "That's the part I can't hold," she said quietly. "It's never seen the place and it already knows the way. The knowing came before the seeing."

Soren got out his notebook. His pencil moved down the page: sun, stars, magnet, smell, low sound. Five lines. He drew a small wire and a smaller bird and did not draw any of the things the bird could feel, because there was no way to draw them.

"If one map fails it has four more," he said. "Cloudy night, it still has the magnet. No magnet near the equator, it still has the stars. It can lose almost everything and still get there."

"We get lost going to the dentist," Maya said.

"We have one map. It has five, and it was born with them."

Maya laughed, and the laugh had something underneath it that wasn't quite happy and wasn't sad either. "I always feel like there's stuff I'm supposed to already know and nobody told me," she said. "Like everyone got a sheet I missed."

Soren looked at the bird. "It got the sheet," he said. "It got it in the egg. It just can't read it until tonight."

The purple was almost dark now. The first real star came out over the chimney, the kind you could find the still point from if you watched long enough.

The swift turned on the wire. It faced south. It had not faced south all day.

Then it dropped off the wire and went, climbing, until the dark over the rooftops took it, and the wire it had been sitting on sprang up and trembled and slowly went still.
