Hi -
I tend to agree - look more like Commons. The surest character for
distinguishing them is tail pattern, and frustratingly I cannot get a good
read on that on any of the photos on my laptop screen. Maybe when I get
back to the desktop and big monitor I will be able to see more.
Seems like there are more Common Terns this summer than the past few years
- Oregon and Washington.
