A few new ones for me:
The females and juveniles are more brown, less white. I think I saw one last time that was female but didn't know what it was.
The banding on the tail is pretty distinctive.
I might have seen these at Prospect Lake a week or so ago but wasn't sure.
These definitely weren't here last time. The geese had moved on and there were interesting ducks everywhere.
Very beautiful; heard its call, too.
