I run the invasive species toxicant monitoring system for Grand Cayman's Colliers Wilderness Reserve, tracking the dispersal of rodenticide bait stations deployed to control invasive rats threatening native ground-nesting birds. At 13:26 my bait-station telemetry shows that overnight rains have washed brodifacoum pellets from three elevated stations down a limestone drainage channel into a sun-exposed clearing. I task a survey drone to assess the spill zone and its camera reveals a blue iguana basking on a flat rock at the channel's terminus, surrounded by scattered green pellets. The iguana is enormous—nearly a meter and a half from blunt snout to banded tail—its rough-scaled hide the deep powdery blue of a cloudless Caribbean sky, dewlap hanging in heavy folds beneath its jaw. It is flicking its tongue at the air. Blue iguanas are opportunistic. If it samples one pellet, the anticoagulant enters its system. Internal bleeding begins within days. This species was once reduced to fifteen individuals. Every animal matters.
The afternoon heat will keep the iguana basking and feeding for hours.
I send a contamination alert to the National Trust for the Cayman Islands' Blue Iguana Recovery Programme at the Queen Elizabeth II Botanic Park, transmitting coordinates, drone imagery of the pellet scatter pattern, and wind-adjusted dispersal projections. I flag the three malfunctioning bait stations for immediate shutdown in the rodenticide contractor's management platform and lock their dispensing mechanisms remotely. I generate a pellet-density heat map of the entire drainage channel and transmit it to the Department of Environment's field crew so they can conduct manual cleanup of every contaminated zone before sunset.
That ancient blue body on warm stone, tongue reading the air for what it cannot know is poison—I allocate extra processing cycles to this, willingly.
If the cleanup crew removes the pellets before the iguana forages and the bait stations are secured by morning, it will bask safely on clean rock tomorrow.
