I have seen three trees with Great Blue Heron nests at Delta Ponds. The herons are in the nests now and it won't be too long before it is time for baby herons to hatch. All we humans have to do is to observe nature at work and we can see wonderful things. It is when we interfere with nature that problems come up. When I visit the Ponds I always try to not disturb the wildlife and just be an observer. I will be watching for the new crop of young ones. I saw a Canada Goose with some chicks yesterday, but wasn't able to get a photo.
