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 →

GBIF citizen-science records
It is estimated from how often the Russet Antshrike is recorded against all the birds logged in Amacayacu National Natural Park (7 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.
