There are a few types of miners in Australia, some are native and other are pests from India. This page features the noisy miners, which are cute, brave, intelligent, and great flyers. They are also very territorial, and they have learned a good way to defend their territory: just fly around any intruder, screaming at it until it leaves. It works. Cats hate it because they like to sneak up on things, and the miner blows its cover.
Dogs hate it because they are afraid they did something wrong (though they don't know what), so they run away quickly and hope that nobody noticed.
Other birds understand to get out of the way. Miners are rarely bothered by humans, so you generally do not need to worry about their alarm unless you get close to the babies.
