01Narrative

The yellow tit, Taiwan yellow tit, or Formosan yellow tit (Machlolophus holsti) is a species of bird in the family Paridae. It is endemic to central Taiwan. Its natural habitat is montane temperate forest. It has a restricted range and small population, and appears to be declining due to large-scale capture for export by the wild bird trade, so it is classed as Near Threatened by the IUCN. The yellow tit was formerly one of the many species in the genus Parus but was moved to Machlolophus after a molecular phylogenetic analysis published in 2013 showed that the members of the new genus formed a distinct clade. Its length is 13 cm. The yellow tit is mostly yellow, with a crest. The crest and back are blackish blue-grey.

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 Parus holsti has left across the world's sequence archives.

Where the DNA of Parus holsti 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.
