Had to go out to Innaloo several times recently. While out there one sunny afternoon last week I spotted a flock of white birds foraging for food. Wasn't sure what species they were at the time but have subsequently learned that they were corellas of some sort. They look most likely to be long-billed corellas -- although that seems a bit odd because they seem confined to the eastern states. Maybe they were on holiday?

Anyway I returned to that area a day or two later and saw another flock of birds doing the same thing nearby. From a distance I thought they were the same species as before but then I was surprised to see that they were actually galahs. Still, they are quite closely related, so it makes sense that they would be foraging for the same kind of food.
