It was a simple evening with the female in her standard roost, and the male coming from somewhere!  They met in their standard place, where we heard both of them.  Then they went north and upstream.  We heard her, the sounds of copulation, then her faint call from way across the stream and we lost them both.  No more endless cries from the female.

It’s hard to know what’s happening.  Is he doing better at hunting and she doesn’t feel the need to call so much?  Or are there hormones calming down and they aren’t going to nest?  Or is it just that it’s gotten cold again?  Who knows.
