Movie 2. A partner of a pair rejected a sprig of Cryptomeria japonica (L.f.) D.Don, which the other brought into the nest.
This is a "Movie 2" of Short Communication "Three types of courtship
behaviour of the Green-backed Heron Butorides striatus in Morioka,
northern Japan" published in Strix,

I report three types of courtship behaviour of the Green-backed
Heron Butorides striatus amurensis observed in Morioka, northern
Japan. The courtship call was heard only a few days during the
paring stage. A male displayed his yellow throat and performed a
short dance close to his partner-to-be. At a courtship and nest-
building stage, a particular bird of pairs was apt to bring sticks
to the nest. Some sticks seemed to be selectively rejected by the
receiver. Green-backed Herons might have preference about nest
materials and/or nest-building effort.
