ID tip
The bronze-tailed thornbill is 13 to 14 cm (5.1 to 5.5 in) long and weighs 5.9 to 6.3 g (0.21 to 0.22 oz). Both sexes have a short straight black bill. Adults are generally bottle green overall, with coppery red uppertail coverts and a forked olive green tail. Adult males have a narrow gorget that is emerald green under the chin and transitions to pink at the bottom. Adult females are similar but the gorget is paler green and does not have the pink "beard"; in addition their outer tail feathers have pale tips. Juveniles resemble adult females with the addition of a mahogany red crown. Voice: The bronze-tailed thornbill makes "a dull short 'tzk'" call; other vocalizations if any are not known.
