Wow, you guys sure get some big birds hanging out in your gardens. The biggest bird we have come to our garden is a Hadeda Ibis. Sorry, I haven´t got a photo of him to put on, but he is pretty huge - maybe like a stork, but with shorter legs. He has a long curved bill, which he uses to dig in the lawn for grubs and worms with. Altogether, he has a pretty comical appearance and a very loud, harsh cry. A cross between the sound of a goose and a foghorn, if you can imagine that. He shouts "hah, hah, hah-de-daa", which is where he gets his name from. If you take one by surprise in the garden, he will fly up with big, clumsy, flapping wings and scream loudly - the combined effect is enough to give you a heart attack!!!
