Ellis found it on the first Tuesday of September.

The map box at the north trailhead stood slightly open when they arrived. Just a quarter inch at the corner of the wooden door.

Ellis stopped walking.

The box held the folded trail maps, spare pencils, and weekly condition summary for visitors using the north path.

The door was never left open.

Ellis opened the notebook.

Door ajar. Investigate.

Walt stayed a few steps behind while Ellis moved closer to the box.

The nest filled the back corner beneath the map shelf. Dry grass. Bark strips. Pencil shavings and soft fibers woven together into a tight bowl against the cedar wall.

Five eggs rested inside.

Small. Pale. Speckled reddish-brown.

A Carolina wren nest.

Ellis stepped back immediately.

Walt leaned forward slightly to look inside the box without touching it.

Neither of them spoke for a moment.

The maps remained stacked neatly beside the nest. One sharpened pencil rested against the fibers near the edge of the bowl.

Ellis wrote carefully in the field notebook.

North trailhead map box occupied. Carolina wren nest confirmed. Five eggs present. Do not disturb.

Then he lowered the wooden door carefully back to its original quarter-inch opening.

Not closed. Not fully open. Exactly where it had been.

They walked back toward WATCHFUL without speaking.

At the landing Ellis checked the condition records for the north trailhead box. The maps had last been restocked five weeks earlier. Pencil supply acceptable. Weekly condition summary outdated by three weeks.

None of it could be replaced without disturbing the nest.

Ellis looked down at the records again. Then at Walt.

“Alternative distribution required,” he said quietly.

Walt had already opened the stern locker.

Inside sat the spare map box from the previous season — a smaller cedar box with a rain cover and supply clip attached to the front.

They carried it together to the south path entrance.

Walt mounted the replacement box onto the secondary post using the bracket hardware from the bow locker while Ellis organized the fresh trail maps beside him on the grass.

Two sharpened pencils. Updated condition summary. Map supply restored.

When the replacement box was secured, Walt tested the mounting bracket once with both hands.

Sound.

Ellis wrote the visitor notice and fastened it beside the closed north trailhead box.

Visitors,

The north trailhead map box is temporarily unavailable.

Current trail maps are available at the south path entrance.

Ellis added the final notes to the condition log.

North trailhead map box occupied by active Carolina wren nest. Five eggs confirmed. Secondary map box installed at south entrance. Weekly monitoring required.

Afterward they walked the north trail to post seven.

All markers sound.

Ellis noted each one.

On the return trip he stopped once more beside the north trailhead box and listened quietly near the quarter-inch opening.

At first he heard nothing.

Then a soft movement inside the cedar box.

Very small.

Ellis stepped back immediately.

The box remained slightly open beneath the early September light.

WATCHFUL carried them home through the main channel while the reeds moved softly along the shoreline.
