Great Blue Heron
Great Blue Heron flyby.
Went to Aylmer to see the tundra swans, they were 500-600 in the ponds with more in the air.
This great blue suddenly flew over the pond and landed at the far edge.
Ardea herodias
Great Blue Herons can hunt day and night thanks to a high percentage of rod-type photoreceptors in their eyes that improve their night vision.
