There Ought To Be a Law

Filardi was moved because, scouring what he called “the remote highlands” of Guadalcanal in the Solomon Islands, he had found a bird he had searched more than two decades for: the moustached kingfisher.

“Described by a single female specimen in the 1920s, two more females brought to collectors by local hunters in the early 1950s, and only glimpsed in the wild once,” he wrote. “Scientists have never observed a male. Its voice and habits are poorly known. Given its history of eluding detection, realistic hopes of finding the bird were slim.”

Yet, defying the odds, Filardi did just that.

After setting mist nets across the forest, he and his team secured a male specimen with a “magnificent all-blue back” and a bright orange face. The discovery brought quite the declaration – “Oh my god, the kingfisher” – and led Filardi to liken it to “a creature of myth come to life”. And then, Filardi killed it – or, in the parlance of scientists, “collected” it.

A researcher on Filardi’s team, it added, “told Audubon that they assessed the state of the population and the state of the habitat, and concluded it was substantial and healthy enough that taking the specimen – the only male ever observed by science – would not affect the population’s success”.

Filardi stressed that, among Guadalcanal locals, the bird is known to be “unremarkably common”. He explained how he and his team made the decision – “neither an easy decision nor one made in the spur of the moment” – to collect the bird with reference to “standard practice for field biologists”. And he said that killing one kingfisher might help save them all.

Right. Because a "successful" population of "unremarkably common" birds needs help to survive.
