I have met many people over the years who come to Addo, or to Africa and just want to see the big five. They travel around the parks so intent on looking for the big animals that they miss the joy of seeing and experiencing the little creatures, like this Bar-throated Apalis.
They are usually referred to as LGBs - little grey birds, because they seem so nondescript when one catches a brief glimpse of them.
But if anyone misses seeing them they can be forgiven, because they are tiny and spend most of their time flitting through the dense bush, looking for prey - they seldom sit still long enough for you to take a photo.
This one popped out of the bushes at Jack's picnic spot and fortunately stopped long enough for me to focus the camera on him.
