I've managed to find a pair of Black-shouldered Kites not far out of Alice Springs. There are lots of Budgerigars around, a few other small birds as well, so there seems to be lots of food. The Kites have hung around for a couple of days so I am thinking they have a nest, and I am fairly sure it is in a clump of Mistletoe, but apart from some squeaking, can't really tell as it is well hidden if the nest is there at all. If it is the nest, it is unlike another I saw a few weeks ago that is much larger and high up in the tree. They are quite good at alerting me when they return to their "tree" with high pitched, short, sharp squeaking. Here are some photos from the pair I've seen in the last couple of days.
