Ha ha ha! My pet mantis, Zorak, saw the hummingbird photos on the monitor and kept trying to attack the screen. I guess he’s hungry. What a scamp!
Hummingbirds regularly live more than 10 years in captivity, and as the site you linke to mentioned, the record is over 12 years even in the wild. (But then most birds live much longer than mammals of equivalent body weight; a shrew, of similar weight to a hummingbird, would rarely live longer than a year.)
Re the praying mantis observations, there is a whole subcategory of hummingbird articles in the literature that consists of “[Such-and-such] observed eating hummingbird.” Besides praying mantises, this includes frogs, trout, large spiders, etc. I recall one article about a hummingbird observed caught by a spiny thistle.
Hummingbirds will attack almost anything; I have seen them chase macaws and large basilisk lizards. That’s probably why the Aztecs called their bloodthirsty war god Huitzilopochtli, the “Southern Hummingbird.”
One of my most interesting sightings in recent years was a Calliope Hummingbird (North America’s smallest bird), one of two that were hanging around in a park near the Cloisters in upper Manhattan in late December a few years ago. They were way out of range, apparently having become lost on migration. (They are normally found in the western mountains.) There was some debate whether to try to catch them so they wouldn’t freeze or starve (it was already quite cold at night, but there were still a few flowers in the park) once conditions got worse. Hopefully they moved south a few days later, but we really don’t know what happened to them.
