Here's what hummingbirds look like when not slowed down;
This was filmed in British Columbia, Canada. Soundtrack is 'The Orient' by Alex Yiannaras.

Birds in Science
Low-quality females prefer low-quality males, at least in the avian world. This is according to research published in the Royal Society journal Proceedings B, testing female zebra finches' taste in males. As adults, the low-quality females showed a preference for the songs of males of the same quality, and for the male birds themselves. Evolutionary biologists previously thought that females would always opt for the best male available.

tetrapodzoology | October 5, 2009
One of the most famous of 'missing' birds is the elusive Night parrot, an obscure nocturnal species discovered by John McDouall Stuart in 1845 (though not named until 1861). Small, reluctant to fly, highly nomadic and cryptically coloured, it's never been well known and even now there are only 23 or so specimens in collections. You might know the Night parrot as Geopsittacus occidentalis but many ornithologists now regard it as so close to the Ground parrot Pezoporus wallicus that both are included within the same genus (and Pezoporus Illiger, 1811 is older than Geopsittacus Gould, 1861).
