I had a rather interesting time doing my woodland survey at Newline today. A large Angus bull which was rather protective of his ladies made for a bit of excitement when I was surveying one of my sites but most of the fun was in the front paddock when I was doing a final sweep looking for Brown Treecreepers (without success). I heard a great ruckus as Noisy Miners all headed in one direction, so I followed thinking perhaps it was a Collared Sparrowhawk that had been active earlier. However, it was not. The miners (about 10) were mobbing at the entrance to a tree hollow and they were joined in the tree by 2 Peewees, 3 Crimson and 2 Eastern Rosellas, 2 SC Cockatoos, 2 Magpies, a BFCS and an Indian Myna. There was no sign of anything in the hollow, although I presume an owl was deep within. The miners and myna returned again and again to the entrance to the hollow without perching and then after about 10 minutes of this a Grey Butcherbird arrived and went and sat on the rim of the hole and peered in for about 2 minutes before moving about a metre away where he remained. I watched the hole from a distance for another 10 minutes or so but nothing appeared and the GBB stayed put, but the others got bored and moved on. Any other suggestions apart from an owl?
