This is the no-colour pair (young female); and juvenile male (I assume he is related to the adult male?). The two family groups tried to remove each other from the big old feed tree - at one stage five shared the tree, but not for long! The juvenile male was often by himself, and the one most likely to be shunted off, so he'd land on a nearby sapling, and wait until he could return. I'm continually amazed by their ability to glide through thick allocasuarina (proving the golfing point, that trees are 90% air!). Photo 4
