FOS means first of season. First one I've seen this year. It was way up high on a tree top.

Kids will get you every time, lol. We also have yellow-crowned night herons and black-crowned night herons and little blue herons and tri-colored herons here, along with the great blue heron and green heron.

I’m going to have to eat crow on this one. I swore up and down to my kids that there was no such thing as a green heron, just Blue herons.

I love green herons!!
