The Sage Thrashers on Antelope Island State Park are busy getting ready for migration and the thrashers hatched this year appear to be almost ready to go. They have matured enough that in the field I have to look for two things to determine whether they are adults or young which is the color of the eyes and whether the gape still shows some lightness at the base.

This young Sage Thrasher was reacting to an adult thrasher perched at the top of the branch yesterday. If I had been in FX mode (full frame) I would have been able to show the behavior of both birds. I’m kicking myself because I didn’t switch sooner.

I know that before long these Sage Thrasher are leaving to head to their wintering grounds and I am grateful for all the time I spent with them this year photographing and observing them from the start of their breeding season until the end.

Life is good.
