The russet antshrike (Thamnistes anabatinus) is a passerine bird in subfamily Myrmornithinae of family Thamnophilidae, the "typical antbirds". It is found in Mexico, every Central American country except El Salvador, Colombia, Ecuador, Venezuela, and possibly Peru.
The russet antshrike was described by the English ornithologists Philip Sclater and Osbert Salvin in 1860. They erected the genus Thamnistes to accommodate the species and coined the binomial name Thamnistes anabatinus. The specific epithet is from the Ancient Greek anabatēs meaning "climber" or "mounter".
The taxonomy of the russet antshrike is unsettled. The International Ornithological Committee (IOC) and the Clements taxonomy assign it these six subspecies: Wikipedia →

Rare
Under 5% of wildlife watchers report a Russet Antshrike sighting in Montes Azules Biosphere Reserve on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 217th most-seen of the 240 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Russet Antshrike is recorded against all the birds logged in Montes Azules Biosphere Reserve (8 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
