    Is it normal for these titmice to keep the eggs covered when the birds are not incubating?
     Tree swallows also build a canopy of feathers over their eggs in nestboxes.  Perhaps it's to discourage predators, especially birds, who stick their heads in the box looking for a meal.
    Also, one pair of Mountain Bluebirds appear to have stopped constructing a nest after putting in a ring of grass about 4" high.  Is this normal?  A pair has begun construction of a nest in another box a ways away but within viewing distance - could this be the same pair that has just switched sites?
     I think there are multiple possibilities:  Perhaps one bird of the pair building the first nest is now building the 2nd nest with a different mate - either through choice or necessity (one bird died or moved/was chased out of the area).  Or perhaps it is the same pair.  Or it could be two different birds!
