Australian White Ibis. Painful birds. Colloquially known as Garbage Guts in Southeast Queensland because they are very aggressive omnivores and scavengers. They are also nightmares for outdoor restaurants.
Someone feeds them in my street. In the last two months, they have learnt to eat the bird seed in the feeder. They also harass and chase the adult and young Bush Stone-curlews to get them to drop their food. I found these, breeding today.
