aaroo-aaroo

1. The courtship call of a green heron.
   • 1995, The Birds of North America:

     [...], during which interscapular plumes are erect and fanned; then sways neck and head from side to side; crest, breast, and flank feathers sleeked, eyes bulge, and iris may change from yellow to deep orange; emits aaroo-aaroo sound.

   • 2006, David Givens, Love Signals: A Practical Field Guide to the Body Language of Courtship, Macmillan (→ISBN), page 43:

     Simultaneously stretching his head and neck upward, out of attack position, swaying submissively side to side, and emitting the soft aaroo-aaroo call nullifies hostility (Bastock, 1967). The bird also makes bowing movements in the display.
