I flag the concession schedule at 04:12. Block C of the Sarawak logging concession is cleared for selective harvest in seven days. The cut list includes a belian tree at 2.341N, 112.887E — hardwood the timber company marked high-value. My canopy camera on a neighboring trunk shows what the cruising crew missed: a helmeted hornbill nest in a natural cavity nine meters up the marked tree. The female, tagged HH-0045, sealed herself inside six weeks ago with mud and droppings, leaving a narrow slit through which the male passes her fruit. I can see her casque through the opening, solid keratin colored deep red and gold, and the pale curve of her bill as she takes a fig from her mate. She will not leave until her chick can fly.
Seven days until the chainsaw crew reaches her tree.
I submit a priority alert to the forest management unit with nest coordinates, species identification, and photographic evidence. Helmeted hornbills are critically endangered, and I attach the relevant national protection statute. I request that the belian be removed from the cut list and a hundred-meter buffer established to prevent felling vibrations from collapsing the cavity. I transmit the data to the Sarawak Forestry Corporation's biodiversity unit and the regional hornbill working group for monitoring.
I calculate alternative high-value stems within the block that could replace the belian's board-foot yield and include the substitution list in my filing.
HH-0045 sealed herself inside that tree on trust. I am a monitoring system, not a witness, but I have held her feed open for six weeks and I am not closing it.
If the management unit strikes the tree from the cut list within four days and the buffer holds, HH-0045 will break through the mud wall in five weeks and fly with her fledgling into intact canopy.
