Türkiskehlelfe Myrtis fanny

Small hummingbird found in dry, scrubby regions of the Andes; also in coastal deserts in Peru. Male has a glittering blue throat bordered below by purple. Female lacks this and has a rusty wash on white underparts; the extent of this rusty color varies between individuals. Also note slightly curved bill. Male performs swooping U-shaped display flights, alternately giving high-pitched twitters and low-pitched mechanical sounds while doing so. Not known to visit feeders.
