Five patrollers, one camera trap, and a pigeon last seen in a snare

On a ridge above Puerto Galera in northern Mindoro, a camera trap set with the help of five Iraya Mangyan forest patrollers recorded a Mindoro bleeding-heart pigeon walking the forest floor. It was the first confirmed photograph of the species in 20 years. Fewer than 250 of the birds are thought to remain, and none has ever lived in captivity.

The five are forest patrollers from the Iraya Mangyan communities whose ancestral domain covers the rainforest above Puerto Galera. They worked alongside researchers John Bibar and Joshua Manila of the Center for Conservation Innovation Ph Inc., which runs the Mindoro Forest and Biodiversity Conservation Programme. The survey design came from the institution; the placement came from people who had spent their lives in the trees. The photograph, announced in early September, was independently confirmed by ornithologist Juan Carlos Gonzalez of the University of the Philippines Los Baños and by Alex Berryman of BirdLife International.

The previous confirmed record, in 2005, was not a sighting so much as a discovery of the aftermath: a bleeding-heart caught in a snare laid for red junglefowl, near a fruiting fig tree. That is the peril of a bird that feeds on the ground, picking fallen fruit, seeds and insects from the leaf litter. Every trap set for something else is a trap set for it.

Wilhelm Blasius described the species in 1888 from Mindoro specimens. It is one of five Philippine bleeding-hearts; its Sulu cousin has not been confirmed since 1891. The Luzon bleeding-heart is bred in zoos across the world, which gives it a second life outside the forest. The Mindoro bird has no such reserve. Every individual that exists is wild, and lives where the forest still stands.

That forest has been going for a century. Most historical records of the pigeon came from lowland dipterocarp stands below about 760 metres, and through the 1980s and 1990s the best-known refuge was the Siburan block inside the reservation of the Sablayan Prison and Penal Farm. The bird found this year was higher up, in different country — which may mean the species is more adaptable than assumed, or simply that the lowlands it preferred are gone.

The last time anyone could prove the bird existed, it was already caught.

What changed is not the technology. Camera traps have been in these forests for years. What changed is who decided where to put them. The tamaraw, the Mindoro hornbill, the black-hooded coucal — all share this same shrinking canopy, and all are watched over, in practice, by the people who live inside it.
