A joint expedition to the Colombian Andes has concluded that the critically endangered yellow-eared parrotlet is extinct, citing the fact that its remaining habitat looked extremely steep and the research team was already tired. The findings, published Tuesday in Nature, establish a new methodological baseline for formally assuming a species has vanished.
A joint expedition to the Colombian Andes has concluded that the critically endangered yellow-eared parrotlet is extinct, citing the fact that its remaining habitat looked extremely steep and the research team was already tired. The findings, published Tuesday in Nature, establish a new methodological baseline for formally assuming a species has vanished.
The team from the Smithsonian National Museum of Natural History and the University of Bogotá spent nearly four hours scanning the lower tree line before finalizing the taxonomic loss. According to the peer-reviewed methodology, the expedition utilized advanced satellite topography to precisely calculate the caloric expenditure required to hike up the muddy ridge where the bird was last sighted in 2011, ultimately determining the biological imperative was outweighed by the ambient humidity. It is genuinely breathtaking to stand at the edge of that ancient, misty cloud forest, contemplating the vastness of an untouched biosphere holding millions of years of evolutionary secrets, and then mutually agree to just head back to the Marriott.
We deployed passive acoustic sensors within a fifty-foot radius of the rented Toyota, and upon recording no avian vocalizations over the sound of our own complaining, the mechanism for extinction became clear.
Independent reviewers have praised the team's efficiency while requesting further data. Dr. Elena Moreno, an evolutionary biologist at Stanford University who was not involved in the paper, noted that while the primary findings are robust, such observational absence requires a rigorous replication. Moreno cautioned that the sample size of researchers looking around casually before lunch is inherently limited, suggesting that future expeditions should at least wait until the late afternoon to declare a genus entirely wiped from the taxonomic record.
The authors have since secured an additional $1.2 million in grant funding to fly to the Seychelles next month, where they plan to assume several elusive deep-water reef fish are also gone without getting into the submersible.
