Fiery-throated Hummingbird vs Red-tailed Comet

Fiery-throated Hummingbird

Panterpe insignis

Tiny6 gForest

The fiery-throated hummingbird is 10.5 to 11 cm (4.1 to 4.3 in) long. Males weigh 5.9 to 6.2 g (0.21 to 0.22 oz) and females 4.9 to 5.2 g (0.17 to 0.18 oz). Within each subspecies the male and female are alike. All have a mostly black bill with a pink base to the mandible and a small white spot behind the eye. The nominate P. i. insignis has a glittering royal blue crown and the rest of the face and nape are black. The back is bright metallic green that becomes bluish green on the uppertail coverts. The tail is blue-black. Voice: The fiery-throated hummingbird does not appear to have a true song. One call is "a repeated nasal, squeaky 'kek...kek...', given in fast series". Another is "a complex fast liquid twittering with sudden squeaky rises in pitch".

Red-tailed Comet

Sappho sparganurus

Tiny5 gShrubland

Male red-tailed comets are 19 to 20 cm (7.5 to 7.9 in) long including their 7 to 10 cm (2.8 to 3.9 in) tail. Females are 12 to 14 cm (4.7 to 5.5 in) long. The species weighs about 4 to 6.5 g (0.14 to 0.23 oz). Adult males of the nominate subspecies have a shining green head with a golden green or emerald green gorget. Their back and rump are reddish purple and their underparts mostly green with buffy undertail coverts. Their tail is long and deeply forked. Its upper surface looks reddish purple to green depending on the angle of the light striking it. Voice: What is thought to be the red-tailed comet's song is "a short, rapid, jumbled chatter". It also makes an "unmelodic tjrrrt" and "rather harsh tsha or zack notes, which may be monotonously repeated at more than 1 s intervals".
