nesting

This is a Google image and not quite right. One of my neighbors has a reddish throat. Maybe it's not a sparrow, though the size is right.

                                                                                    

Bit by tendril by browned bit of grass by twig, a boy and girl sparrow are building a nest under the front eave. Others have done the same in the same place in the past. Are they descendants of the ones I first saw there years ago? Are they the same duet? I have no clue how long sparrows live, but I feel charmed by their efforts.
