For anyone that hasn’t been in the presence of a hadeda, they sound kind of like the kid on the Simpson’s show that always says “HA HA”. Honestly, if you get a large group of them, they can get a bit irritating after a time. I think more than one ranger I’ve met has described them as the most annoying creature in the bush.
Now about this photo. I flagged it quite some time ago to edit, and couldn’t figure out the reason why, other than I liked it. But after staring at it for the last 20 minutes, I think the two things I like are the contrasts (the bright highlights and dark shadows and the flash of iridescent feathers against a flat sky) and that the shape of the bird is repeated in the shape of the branches (look to the branch directly below the tail, it has the shape of a head and beak). The monochrome treatment highlights what I like about the image, whereas the colour version is pretty easy to overlook.
Sometimes I find it difficult to explain what draws me to one photo over another; I often find myself at a loss for words when someone is looking for a critique on an image. I know very quickly whether I like an image or not; but the reason why isn’t always easy to put into words.
