Last year we watched while Great Blue Herons nested and had one youngster in a tree in the middle of the conservation wetland behind our new home. We noticed activity recently so today I took some photos, and confirmed that they are back nesting there again …
Here’s our view; the tree with nest is visible in the second rear panel from right (not the closer/bigger tree to it’s left); now, with my new high zoom camera, let’s get closer, and closer still … and finally at maximum zoom (50x optical, and cropped)! A quite amazing level of zoom, compared to the top view where you can hardly even see the nest:
I’m sure there will be more photos of the nest, over the next few months …

They tell a story and are amazing. Wonderful results.
Amazing! Are these birds endangered at all?
I’m sure they are not, we see them often around here – they’re quite timid so I don’t get to photograph them very often.
