I’ve been following a pair of Trumpeter Swans for about 4 years, and they’ve just accomplished their second successful nesting, a single cygnet probably 1-2 days old now. I\ve been checking the nest almost daily, so it was a big deal for me to fimally see this little guy.
I could tell you a lot about Trumpeter Swans, but The Trumpeter Swan Society has been protecting them for years and they have a lot of info.: https://www.trumpeterswansociety.org/
This site is about the images I got, and here they are.
