Wild Australian magpies are inquisitive, wise, friendly, and fun to interact with. Like most creatures, they are usually respectful to you, if you are respectful of them.
But, they do swoop!
Swooping means they attack humans, other animals, cars, etc., causing about a thousand human injuries in Australia each spring. See:
They swoop if they perceive their nestlings are in danger….
or maybe, if they are having an irritating day.
Like all corvids, they have excellent memories and hold grudges, so if you bothered a corvid in the past, you better steer clear during swooping season, or else be ready to duck down really fast!
Cheers to you from Australia’s marvelous-memoried, moody-magpies~
