Hi, a Kookaburra in the tree in my front yard has been making a sqawking noise for 3 days and nights off and on.. It's not the normal Kookaburra laugh.. Any thoughts as to why this is? Maybe to deter other birds? I don't know much about them - It appears to be a full-grown bird. I'm not sure if there is a nest, or even if it's nesting time. I'm in Sydney.
