This is Bess.
She is still bringing nesting material into the nest box. This is some green moss.
She dumps it and does a nesting wriggle.
Here comes Spikey!
She, too, has some nesting material - hay in her case.
She moves over Bess and gives her a push with her left foot.
Bess gets the message and gets up to go.
Off goes Bess!
Spikey watches her go . . .
. . . and then goes herself . . .
. . . leaving an empty nest box with its 8(?) eggs.
(Remember, there were 6 eggs yesterday!)
