Vocalizations produced in Elaborate Social Display of at least 15 Blue Jays.
观察细节
Possibly more. All sitting in ice-covered bushes at front entrance, engaging in the Elaborate Social Display, described in BNA. Much wheedle-calling and bobbing. Frequent rattles. Occasionally broken up by "jay" calls from birds not in the group. Near the end of my observation jays were dropping into the feeder garden and getting food that they brought back and allofed another jay. That action seemed to stimulate a new response of the group to wheedle-call and bob more.
