Shep, amazing how tolerant the resident pair is with sub-adult visitors when it is not breeding or nesting season.
BL -- thanks for the name of the Hatchery pair's favorite bluff perch. But, I hope RRP/Explore will re-consider. Bluff Perch Tree acronym of BPT is going to be confusing with the North nest's Brush Pile Tree's same acronym of BPT. Many of us watch both locations. Yikes!
