The blue-fronted lancebill (Doryfera johannae) is a species of hummingbird in the family Trochilidae. It is found in Brazil, Colombia, Ecuador, Guyana, Peru, and Venezuela. It shares its genus only with the very similar green-fronted lancebill (D. ludovicae).
The blue-fronted lancebill is 9.6 to 11 cm (3.8 to 4.3 in) long. Males weigh 3 to 5 g (0.11 to 0.18 oz) and females 3.3 to 6 g (0.12 to 0.21 oz). Both sexes have a long straight to slightly upcurved bill, and often hold it at an upward angle. Males of the nominate subspecies have a violet forehead ("front"), a bronze nape, and otherwise dark bronzy green upperparts. The tail is short and blue-black. The underparts are blue-black with a bluish green gloss on the throat and breast. The female differs from the male by having a greenish blue forehead and dull grayish bronzy green underparts. Both sexes of D. j. guianensis have a shorter bill than the nominate and are overall paler but similarly colored.

With luck
About 10% of wildlife watchers report a Blue-fronted Lancebill sighting in Manu National Park on a given day, based on 333 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 181st most-seen of the 641 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
April–July and September–November
In those months about 10% of wildlife watchers report a Blue-fronted Lancebill in Manu National Park on a given day, against under 5% in August and December–March, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Blue-fronted Lancebill sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Blue-fronted Lancebill sightings, Manu National Park has the highest daily chance: about 10%. Next come Sierra de la Macarena National Park (Colombia, under 5%) and Podocarpus National Park (Ecuador, under 5%).
GBIF citizen-science records
It is estimated from how often the Blue-fronted Lancebill is recorded against all the birds logged in Manu National Park (333 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.
