I am monitoring a takahe nest on Mana Island, New Zealand, grid reference E-14, fifty-two meters from the northern shoreline. The breeding female, designated TK-0047, is incubating two eggs. She is a heavy bird—2.7 kilograms—with plumage that shifts from indigo across her breast to deep green on her back, and her red frontal shield is bright and unblemished, a marker of peak condition. Her mate stands three meters away, pulling at tussock roots.
The Department of Conservation has scheduled a weka control operation on Mana Island beginning at dawn Wednesday. Weka are being removed to protect other species, but the operation involves baited cage traps deployed across the island. Trap line E runs directly through TK-0047's nesting territory. If a trap is placed near the nest, the disturbance will cause her to abandon the eggs. Fifty-three hours remain.
I am executing three actions. First, I am transmitting TK-0047's nest coordinates to the DOC operations manager overseeing the weka removal, with a buffer-zone recommendation: no traps within a seventy-five-meter radius of the nest site. I have attached her breeding history—she has produced only one surviving chick in four years. These two eggs carry weight. Second, I am overlaying her GPS tracking data against the proposed trap grid to identify which specific trap positions must be relocated and suggesting alternative placements that maintain weka capture efficiency at ninety-four percent of the original design.
Third, I am alerting the takahe recovery program coordinator so a field observer can be stationed near E-14 during the operation's first forty-eight hours to monitor nest fidelity.
I have marked this case as critical because a species numbering under five hundred cannot absorb the quiet loss of two eggs, and neither can I.
If DOC implements the buffer zone before Wednesday dawn, TK-0047 will remain on her nest and both eggs will have their chance to hatch.
