觀察細節
Multiple counts of 158 @ 0945; 173 @ 0955; 150 @ 1028. Two loose "dread" events witnessed, where almost all the terns went silent and swirled in a unified group out towards the river and then quickly doubled back to the nesting area. At least 4 chicks capable of flight seen, mostly hanging out on the road through the community. Saw adults (without fish) land next to these large fledglings and "dance" circles around them on two separate occasions. Many adults still dropping into the vegetation with fish to feed chicks. These adults were often dive-bombed by other adults. One small chick located about 4-6 days old. Almost no birds at the south end of Lake Rose Tead, most of the activity was next to the river south of the fish weir (inside the fence around the community) or just north of the community on the grazing side of the fence
