Throughout the process, we discussed references to hummingbirds. But the final iteration is closer to a mountain bluebird.

The mountain bluebird (Sialia currucoides) is a medium-sized bird weighing about 30 g (1.1 oz) with a length from 16–20 cm (6.3–7.9 in). They have light underbellies and black eyes. Adult males have thin bills and are bright turquoise-blue and somewhat lighter underneath. Adult females have duller blue wings and tail, grey breast, grey crown, throat and back. In fresh fall plumage, the female’s throat and breast are tinged with red-orange, brownish near the flank contrasting with white tail underparts. Their call is a thin ‘few’; while their song is warbled high ‘chur chur’. It is the state bird of Idaho and Nevada. It is an omnivore and it can live 6 to 10 years in the wild. It eats spiders, grasshoppers, flies and other insects, and small fruits. The mountain bluebird is a relative of the eastern and western bluebirds.
