Abstract
A captured couple of the Japanese Bullfinch Pyrrhula pyrrhula griseiventris LAFRESNAYE bred in a handy cage, and an old male as well as a young male lived more than ten years in the indoor cage.
Which facts were brought up within a work as a hobby of Dr. Tetsuro IKEDA, the former chief scientist of the International Latitude Observatory, Mizusawa City. The most data are based on Mrs. IKEDA'S diary.
The old male was brought into the cage in October, 1958, the female followed about a month later, three chickens hatched on June 1, 1959.
The old birds were mainly fed with the seeds of Perilla frutescens, and vegetables and fruits were given subsidiarily.
Dr. IKEDA collected insets and worms for the chickens, and their parents gave them to the chickens successfully.
The old female and two youngs were lost on earlier days by escape or death, the survived old male closed his longevity in senility on Oct. 9, 1969, and the young dead on Feb. 12, 1970.
