Birds and trees

Yesterday I went to the Fill to look for wood ducks or ring-necked ducks. Found neither, nor any swallows for that matter, maybe they had only been passing through when I saw them last week.  I did see a pair of red-breasted mergansers. So, today I go look for the butterflies, which I don't find. However, there was a pair of ring-necked ducks diving in the fountain. I wonder what they find for food there? Then walked through the rookery, counted 19 nests in a 2-3 trees, when I walked back through later I could see the massive herons standing above many of the nests. I'm always amazed at how they build on the thinnest of branches.  Walking through the forested areas always makes me feel so much more peaceful. I have the same experience with music.
