Gould's jewelfront or Gould's brilliant (Heliodoxa aurescens) is a medium-sized hummingbird in the family Trochilidae. It is found in tropical and equatorial South America. This is an uncommon species with an unusually large range compared to the other members of Heliodoxa.
The common name commemorates the English ornithologist and bird artist John Gould (1804–1881). H.aurescens ranges in size from 11 to 12 cm, with an average weight of about 6.2 g. This is a sexually dimorphic species with minor differences in plumage and bill lengths between sexes. Both sexes have a narrow frontlet of glittering purplish-blue which is underdeveloped in immature individuals. The bill, black to dark coloured is "unspecialised" being relatively short and straight; while the irises are brown and tarsus black. The tail is forked with the central pair of feathers bronze-green while the other tail feathers have chestnut edges and bronze-green tips. Undertail coverts are a deep fawn colour and wings are purplish-brown. It is noted that there is some variation in plumage for this species, but these differences do not relate to location and is minimal when considering the wide range.

Rare
Under 5% of wildlife watchers report a Gould's Jewelfront sighting in Amacayacu National Natural Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 419th most-seen of the 436 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Gould's Jewelfront in Amacayacu National Natural Park on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Gould's Jewelfront sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 parks where we can rate Gould's Jewelfront sightings, Amacayacu National Natural Park ranks 4th at under 5%. The best odds are in Manu National Park (Peru, about 30%), Tambopata National Reserve (Peru, under 5%) and Yasuní National Park (Ecuador, under 5%).
Same family: Trochilidae
The closest relatives of the Gould's Jewelfront that you can see in Amacayacu National Natural Park (family Trochilidae, Hummingbirds) are Glittering-throated Emerald (about 20%), White-bearded Hermit (about 10%) and Olive-spotted Hummingbird (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gould's Jewelfront is recorded against all the birds logged in Amacayacu National Natural Park (5 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.
