The behavior of Yellow-lored Parrot has not been studied in detail. Yellow-lored Parrots occur in large flocks while foraging during the day and when roosting at night. They fly in flocks from roosting to foraging sites; large flocks are observed flying daily from mainland Mexico to Cozumel Island to forage, and then returning to the mainland to roost (Howell and Webb 1995). When they reach their foraging sites they are largely silent.
There is no information on territoriality or home range size in Yellow-lored Parrot. Presumably this species is similar to other amazons, in that it does not defend a feeding territory but when breeding defends an area around the nesting cavity.
Undescribed; presumably is at least socially monogamous.
Social and interspecific behavior
Yellow-lored Parrot is a highly social species that rarely is seen as solitary individuals. They fly in big groups of more than 30 individuals, composed of pairs and family groups. Groups can be detected easily due to their very loud calls; they roost and sleep in big groups, in some cases of more than 1500 individuals, at elevated sites and in large tree tops.
No reports of predation on Yellow-lored Parrot?
