Abstract
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.
