Gould's Jewelfront

Heliodoxa aurescens

Tiny6 gForest

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.

Violet-fronted Brilliant

Heliodoxa leadbeateri

Tiny7 gForest

The violet-fronted brilliant is 11 to 13 cm (4.3 to 5.1 in) long. Males weigh 7.1 to 8.5 g (0.25 to 0.30 oz) and females 6.6 to 7.5 g (0.23 to 0.26 oz). Both sexes have a medium length, almost straight, black bill, a white malar streak, and a small white spot behind the eye. They both have a forked tail but the female's is less deeply indented than the male's. Males of the nominate subspecies have bronzy green upperparts with a glittering blue forehead and a coppery neck. They have a glittering emerald green gorget and a dull bronzy green breast and belly. Voice: What is thought to be the violet-brilliant's song is "a continuous series of single strident 'chup' or 'tchep' notes". It also makes "a repeated, bright, descending phrase 'whee-tsee-tsee-tsew' that sounds like a jerky twittering."
