And on a happier note, years ago a female Anna's at my feeder was buzzed by
a maler, causing the female to exit rapidly, only to fly into and be
impaled, like a dart, on a nearby, open, screen door. It struggled to
extract itself of course, and when It seemed 'stuck' I headed out to
assist, but it succeeded in getting free and flew off as I arrived.. No
hummers were injured in this case.
