An Osprey was observed to eat a Buttonquail beside a sugarcane field in Tarama-jima Island, Okinawa Prefecture on April 29, 2014. After a while the hawk suddenly flew away. It is likely that Ospreys sometimes capture Buttonquails in this island because this island is lacking in diversity of foraging habitats suitable for them. No food items other than fish have been reported for Ospreys in Japan apart from this report.
