The Esmeraldas antbird (Sipia nigricauda) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Colombia and Ecuador. The Esmeraldas antbird has a complicated taxonomic history. It was described by the naturalists Osbert Salvin and Frederick DuCane Godman in 1892 and given the binomial name Myrmeciza nigricauda. It was later reassigned as a subspecies of Myrmeciza laemosticta. At about the same time, M. laemosticta was moved into a new genus, Sipia. The original description was of a female bird and this was later the source of taxonomic confusion. The male bird was considered a different species (Sipia rosenbergi) until in 1991 it was realized that the two taxa were simply the male and female forms of the same species. The authors of the 1991 paper promoted nigricauda to species rank and by the principle of priority the specific epithet rosenbergi disappeared. In addition, the authors merged Sipia back into Myrmeciza. A molecular phylogenetic study published in 2013 found that the genus Myrmeciza, as then defined, was polyphyletic. In the resulting rearrangement to create monophyletic genera,... Wikipedia →

Rare
Under 5% of wildlife watchers report an Esmeraldas Antbird sighting in Farallones de Cali National Natural Park on a given day, based on 80 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 289th most-seen of the 542 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.
June and August–September
In those months about 10% of wildlife watchers report an Esmeraldas Antbird in Farallones de Cali National Natural Park on a given day, against under 5% in July and October–May, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Esmeraldas Antbird sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Farallones de Cali National Natural Park, in our data
Farallones de Cali National Natural Park is the only park on Wallace's Line with enough records to rate Esmeraldas Antbird sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Esmeraldas Antbird is recorded against all the birds logged in Farallones de Cali National Natural Park (80 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.
