Large Flock of Corellas Caw on Front Lawn

Occurred on April 25, 2021 / Brisbane, Queensland, Australia

Info from Licensor: "I usually feed a few of these corellas. This morning I was trying to have a little extra snooze, but the noise was too loud. So I peeked outside and it looked like an 'invasion of the Corella Bird'. So my usual few, must of told their mates. After this video more came, till eventually they flew off after a neighbor walked passed with their dog."
