On Friday I went to check on the herons and was thrilled to discover that the mini colony next to the Paul Allen building now hosts six nests--four more than I saw two weeks ago. These herons are obviously the cool kids on the block, breaking into a new real estate market.
As the nests are newer, they were much more actively hunting for material than those old school herons 100 yards to the west.
This nest is definitely newer as it appears less dense from the ground. The two birds are squeezed in side by side, almost spilling out beyond the nascent structure's perimeter.
