A follow up to sighting 4427622. There are two Owlet-nightjars at ANBG within tree hollows a few metres apart. The third and fourth images show the bird from earlier sighting 4427622. To the left and behind this bird is another tree hollow with a second bird, as shown in the first two images. The final image shows the two tree hollows, one to the centre left and the other to the centre right. Thanks to Marcus for the initial sighting last week and to Barbara for the initial sighting of the second bird today.
