The collared antshrike (Thamnophilus bernardi) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Ecuador and Peru. The collared antshrike was described by the French naturalist René Lesson in 1844 and given the binomial name Thamnophilus bernardi (the genus was misspelled as Tamnophilus) with the type locality of Guayaquil in Ecuador. The specific epithet honors Captain Bernard, a French mariner and collector from Bordeaux. The collared antshrike was subsequently placed in the genus Sakesphorus. A molecular phylogenetic study published in 2007 found that Sakesphorus was polyphyletic and that three species including the collared antshrike were embedded within a clade containing members of Thamnophilus. The collared antshrike was therefore moved back to its original genus.
The collared antshrike's further taxonomy is unsettled. Carriker... Wikipedia →

With luck
About 10% of wildlife watchers report a Collared Antshrike sighting in Guayaquil on a given day, based on 68 verified sightings from GBIF citizen-science data. It is the 65th most-seen of the 167 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
November and December
In those months about 20% of wildlife watchers report a Collared Antshrike in Guayaquil on a given day, against under 5% in February–May and July–August, the lowest months. Those are among Guayaquil's driest months, with about 15 mm of rain a month against 220 mm in February.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Collared Antshrike sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Guayaquil, in our data
Guayaquil is the only city on Wallace's Line with enough records to rate Collared Antshrike sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Collared Antshrike is recorded against all the birds logged in Guayaquil (68 verified sightings), 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.
