Lisa - there's definitely guyliner, but I'm hesitant to guess that it's beloved DM2 taking a break from N3 while Mom incubates & I can't spot a brood patch from the cam angles. Great photos!
Buzbee - thanks for the tip!
The beak was what caught my eye & to my non-eagle eyes it didn't look like DM2's beak.
