The black-crested warbler (Myiothlypis nigrocristata) is a species of bird in the family Parulidae, the New World warblers. It is found in Colombia, Ecuador, Peru, and Venezuela. The black-crested warbler was formally described in 1840 with the binomial Trichas nigro-cristatus. For a time it was placed in genus Basileuterus. By 2012 the IOC had assigned it to Myiothlypis. BirdLife International's Handbook of the Birds of the World (HBW) did so in 2016.
The black-crested warbler is monotypic. However, for a time what is now subspecies euophrys of the citrine warbler (Myiothlypis luteoviridis) was treated as a subspecies of it. The black-crested warbler is about 13.5 cm (5.3 in) long and weighs about 11 to 20 g (0.39 to 0.71 oz). The sexes have the same plumage. Adults have a narrow black crown stripe, a wide yellow supercilium, a black stripe through the eye, a yellow crescent under the eye, and olive-green cheeks and ear coverts. Their nape, upperparts, wings, and tail are olive-green. Their throat and underparts are yellow. They have a dark iris, a blackish bill, and orange-yellow legs and feet. Juveniles have a dusky olive-gray head... Wikipedia →

Rare
Under 5% of wildlife watchers report a Black-crested Warbler sighting in Bogota on a given day, based on 142 verified sightings from GBIF citizen-science data. It is the 94th most-seen of the 231 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.
April
In that month about 10% of wildlife watchers report a Black-crested Warbler in Bogota on a given day, against under 5% in May to March, the lowest months. That is one of Bogota's wettest months, with about 210 mm of rain against 45 mm in January.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Black-crested Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 3
Of the 3 cities where we can rate Black-crested Warbler sightings, Bogota ranks 2nd at under 5%. The best odds are in Quito (Ecuador, about 20%).
Same family: Parulidae
The closest relatives of the Black-crested Warbler that you can see in Bogota (family Parulidae, New World Warblers) are Blackburnian Warbler (about 20%), Yellow Warbler (about 10%) and Tennessee Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-crested Warbler is recorded against all the birds logged in Bogota (142 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.
