The crossing went badly for exactly three minutes, and Pascal had planned for all of it. The group assembled at the canyon mouth as first light reached the upper rim. Seven tortoises, five collared lizards, eleven assorted smaller lizards, and Gram at the front of the tortoise column.
The Gila woodpecker declined to cross on foot — it would fly the route at altitude and meet them at the secondary basin. Sensible. Pascal positioned himself at the leading point of the group.
Kira took the rear. They moved. The first two hundred feet of the route ran along the base of the east canyon wall, in shadow that would persist for another forty minutes.
This section moved well. The tortoises were slow but steady. The smaller lizards moved faster and had to be periodically halted to keep the group compact rather than strung out along five hundred feet of trail where the rear could not see the front.
The gravel pan crossing began at the canyon mouth, where the shadow ended and the open desert began. The hawk was already up. Pascal had expected this.
The bird was working a thermal column that rose from the dark rock of the canyon wall — the same thermal pattern he had observed the previous afternoon, but starting earlier because the wall had retained more heat through the warm night. He had planned for the hawk. He had not planned for there to be two hawks.
The second bird was further east, working a separate thermal above the gravel pan itself. An eastern red-tail, different from the first bird's species, and positioned precisely above the longest open gap in the crossing route. Pascal assessed this in approximately four seconds.
Two hawks, two thermal columns, one crossing. The group was at the canyon mouth. Stopping here and waiting was not viable — the shade would retreat as the sun climbed, and the tortoises could not survive extended exposure on open ground in full summer heat.
He had to cross. He made a decision. He moved to a flat, elevated rock at the canyon mouth — fully exposed, fully visible against the morning sky — and shifted his scales to their most extreme chromatic state.
Not camouflage. The opposite. Chameleons under extreme stress could produce a display state — high-contrast bands of orange and green against a dark body background, a threat display that looked, from a distance, like a larger and more dangerous animal than Pascal actually was.
He had never used a threat display to redirect a hawk. He did not know for certain that it would work. But the red-tail was responding to movement and contrast, not species identification, and a sudden burst of high-contrast chromatic activity at the canyon mouth was a stimulus that would be processed before the bird's slower pattern-matching systems could override the initial response.
He shifted. Full orange-green threat pattern. Then he moved.
Not toward the gravel pan. Lateral, along the canyon mouth rock, fast, maximum visual contrast and motion combined. The eastern red-tail broke its pattern.
Its thermal work stopped and it turned toward the canyon mouth. Pascal dropped behind a boulder and went immediately to full gravel-pan match — pale tan, dark stippling, white mineral patches. The bird made one pass over the canyon mouth, found nothing that matched what had triggered its response, and returned to its thermal.
Confused, not threatened. Confused was what he needed. In the forty seconds of the bird's attention diversion, Kira had moved the group across the first seventy feet of open crossing — past the longest exposed gap.
She had read what he was doing and acted on it without instruction. He caught up to the group at the third creosote bush and took his position at the front. The rest of the crossing took eleven minutes.
Neither hawk struck. When the last tortoise cleared the secondary basin edge and moved into the shade of the basin's north-facing cliff, Kira touched Pascal's foreleg with her own — the quick lateral contact that her species used as a social acknowledgment. He accepted it.
"Good call on the display," she said.
"It worked," he said.
"That's the standard I was using."
They looked back at Sunspire Canyon, two miles away, its red spires catching the full morning light. Then he turned his attention to what had to happen next.
The desert at dusk belonged to a different cast of creatures than the daylight world. Sage watched the evening stars emerge between the high sandstone walls, his turret eyes rotating independently as he catalogued the canyon's shifting night geography.
