The russet-crowned motmot (Momotus mexicanus) is a species of motmot native to north-western Mexico and central Guatemala. It is a year-round resident of the tropical and subtropical dry broadleaf forests and scrubland. The russet-crowned motmot is the most understudied species of motmot in the family Momotidae. "Russet" refers to the reddish-brown colour of the bird's head and originates from the Latin russus meaning red.

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 Momotus mexicanus has left across the world's sequence archives.

▸ drag or hover over the strip to read any position — letter and how much it varies
Violet ticks below the strip = positions where individuals differ; flat = the species' unchanging signature. 95% of positions are identical in every specimen.
Where individuals differ — all 30 variable positions, in barcode order
Each circle is a barcode variant; bigger = more specimens, colour = region. Lines join the most similar variants and the tick marks count the mutations between them — a tight cluster is one “dialect”, a long line a more divergent lineage. Click a circle to list its actual specimens.

The species whose COI barcode is most similar to this one — a quick “who is this most like”. The percentage is how much the barcode differs; it approximates, but is not, the full evolutionary tree.

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.
