She's quite proud of her nest.

My belief that she has one or more eggs is purely circumstantial, in that she becomes glued to the nest when it is wet or cold. As it warms up, she'll take longer excursions away, but rarely for longer than 15 minutes or so.

I don't know if I've seen the male partner in the nest. I've seen them taking fun trips way up 1/4 mile or so, then come rapidly down with one coming back to the nest. This happens about every other day.
