The Norths are taking good care of their two eggs today, but so far, not showing off both of them at the same time!
At changeover about 9:30 AM, MrN brought some grasses, deposited them on DNF's back, then they both left the nest for a short mating session in a nearby tree. So perhaps a third egg???
In closeups at 10:30, the view includes a length of binder twine next to MrN. See blue marking in pic. Binder twine is used to bale hay, and probably got picked up with a load of nest materials. It could be hazardous if it is tied in a loop. So hope that it gets buried deep in the nest soon.
