'One of my strongest memories of last summer in the Blue Mountains, through long days thick with smoke, weighed down by a dry baking heat, was the palpable presence of an absence, a silence of birds. To be sure, there were many new sounds to take their place: helicopters and sirens, sometimes howling winds, and for those unlucky enough to be at the fire front, the roaring of flames. But a little further from the action, in still moments, I remember the eerie silence. In this part of the world, though rarely seen or heard even at the best of times, one of the birds now missing in this new way was the regent honeyeater. Having only recently become aware of these incredible, threatened, neighbours, I watched on with a growing sense of dread as the fires moved through some of their last remaining breeding sites, at the height of what should have been their breeding season.'
