Brief SummaryRead full entry
BiologyFlocks of Amami jays can be found wandering through their preferred habitat, mature evergreen forest, searching for their main food source, acorns of the Castanopsis cuspidata tree. These flocks are generally small, but groups of up to 100 have been reported. It is rarely seen feeding in the trees, preferring instead to forage among leaf litter on the forest floor, and will often store the food it finds for the winter. As well as acorns, the Amami jay consumes sweet potato, insects and reptiles, such as grass lizards and the poisonous Okinawa pit-viper (3). The Amami jay breeds from late January until May, when it will lay three to four eggs in nests on low tree branches, in tree holes, or occasionally on the ground or on buildings. The adults protect small territories around the nesting site, and chicks fledge in mid to late March (3).
