Green Mango
Anthracothorax viridis
The green mango is 11 to 14 cm (4.3 to 5.5 in) long and weighs about 7 g (0.25 oz). The sexes are alike except that the female has a tiny white spot behind the eye. Adults' upperparts are emerald green, their underparts metallic blue-green, and their tail metallic blue-black with white tips to its feathers. Immatures have a brownish tinge to the head and back. Voice: The green mango is not highly vocal. It does have a song, "a repeated high-pitched phrase commencing with a drawn-out buzz, 'szzzzz-szi-szi-chup-tsz-tsz.....'." Its calls include "a repeated short 'tsik' and a high-pitched twittering trill." It makes harsh rattles and chatters during agonistic encounters.

Purple-collared Woodstar
Myrtis fanny
The purple-collared woodstar is 7.5 to 8 cm (3.0 to 3.1 in) long and weighs 2.3 to 2.5 g (0.081 to 0.088 oz). Both sexes have a short, decurved, black bill. Their upperparts are bronze-green. Males have an iridescent aquamarine gorget with a shiny violet band below it. The rest of the underparts are dirty white. The long forked tail is dusky brown glossed with light green. The female's underparts are buff, with a bit of white on the throat and belly. Voice: The male purple-collared woodstar makes "a series of twittering 'ti-ti-ti-trl' phrases" at the top of its courtship flight, and at the bottom (mechanically) makes "a remarkable, nasal-sounding 'anh-anh-anh-anh-anh'". In a chase it makes "a fast, high-pitched, descending twittering 'ti-ti-ti-ti'", and another call is "a fast dry 'chi-chi-chi'".
