Mama Mallard, Ready for Egg Delivery

This duck couple are back again; she is ready
to deliver her eggs...She raised a clutch last year
right next to the outer stairs and door of the local
fitness center.  There she sat, patiently brooding
her eggs while fitness center clients  flowed
back and forth right by her.  When her clutch
hatched, the duck rescuers were called and
she and her new family were caught and delivered
to a safer site with water.  Now she is back, and
as of Saturday last, had not begun laying her
eggs, but apparently will nest in the same area
this spring.  I will go there this morning; hopefully
I will spot her!
