01Narrative

The forest owlet (Athene blewitti) is endemic to the forests of central India. It is listed as Endangered on the IUCN Red List since 2018, as the population is estimated at less than 1,000 mature individuals. It is threatened foremost by deforestation. It is a member of the typical owl family Strigidae, and was first described in 1873. As it was not sighted after 1884, it was considered extinct for many years. In 1997, it was rediscovered by Pamela Rasmussen. Searches in the locality mentioned on the label of the last collected specimen failed, and it turned out that the specimen had been stolen from the British Museum by Richard Meinertzhagen and resubmitted with a label bearing false locality information.

05DNA & barcoding6 eDNA hits

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Heteroglaux blewitti has left across the world's sequence archives.

09Environmental DNA6 detections

Where the DNA of Heteroglaux blewitti was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
