Communication and Perception
White-throated magpie-jays are very vocal, with several different types of calls. Mobbing calls and predator alarms are similar: both consist of a harsh, noisy call that varies in length and rate, depending on the particular threat. In general, the loudest and most vigorous mobbing calls have been noted when nests are approached. Both chicks and adults beg for food, making loud whining vocalizations to entice feeding. Females incubating a clutch will notably beg for up to several hours, and rarely forage during this time. Other social calls include low "chirring", usually produced during mating attempts and during nest-building.
