The black-lored yellowthroat (Geothlypis auricularis) is a species of bird in the family Parulidae, the New World warblers. It is found in Ecuador and Peru. The black-lored yellowthroat was formally described in 1883 with its current binomial Geothlypis auricularis.
The black-lored yellowthroat's further taxonomy is not fully resolved. Well into the twenty-first century it was treated as a subspecies of the masked yellowthroat (Geothlypis aequinoctialis). In 2015 the IOC recognized it again as a full species. BirdLife International's Handbook of the Birds of the World (HBW) recognized it in 2017 and the Clements taxonomy in 2022. The initial version of AviList in 2025 also treats it as a species. However, the South American Classification Committee retains it as a subspecies of the masked yellowthroat.
Some authors have suggested that they should both be treated as full species. The black-lored yellowthroat is 12.5 to 14 cm (4.9 to 5.5 in) long and weighs about 8 to 11 g (0.28 to 0.39 oz). The species... Wikipedia →

Rare
Under 5% of wildlife watchers report a Black-lored Yellowthroat sighting in Machalilla National Park on a given day, based on 21 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 157th most-seen of the 248 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.
February, May and October
In those months about 10% of wildlife watchers report a Black-lored Yellowthroat in Machalilla National Park on a given day, against under 5% in March–April, June–September and November–January, the lowest months. Those are among Machalilla National Park's wettest months, with about 60 mm of rain a month against 5 mm in September.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Black-lored Yellowthroat 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 Machalilla National Park, in our data
Machalilla National Park is the only park on Wallace's Line with enough records to rate Black-lored Yellowthroat sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Parulidae
The closest relatives of the Black-lored Yellowthroat that you can see in Machalilla National Park (family Parulidae, New World Warblers) are Tropical Parula (about 20%), Gray-and-gold Warbler (about 10%) and Buff-rumped Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-lored Yellowthroat is recorded against all the birds logged in Machalilla National Park (21 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.
