Due to the lack of a diaphragm and vocal cords, the birds perform breathe with a fixed lung like mechanism of the bellows, and vibrates at least equal to or more than one pair of muscles which adhered to the tracheal ampulla to make a FM sound. Japanese Bush Warbler sings like "Hoh Hokekyo", the first phrase"Hoh" is derived from the inspiratory-phase and the 2nd phrase"Hokekyo" is derived from the expiratory-phase. This bird is one of the most popular in Japanese culture as the word conveys spring. The total number of 51 poems related to Japanese Bush Warbler were collected in the Manyoshu that is the oldest existing collection of Japanese poetry, compiled sometime in the Nara period (about 759 A.D.). The anthology is one of the most revered of Japan's poetic compilations. The compiler, or the final in a series of compilers, is believed to be Ōtomo no Yakamochi. By the way, the Little Cockoo lays eggs "brood parasites" in the nest of the Japanese Bush Warbler in the main land of Japan except for Hokkaido. The Japanese birder gets a good opportunity to take photographs of the Little Cuckoo, if holding a camera around the nest of this bird (see Little Cuckoo HDTV by JH1RNZ). This HDTV was captured in mid-June 2009 at Hegura island, about 50 km off shore from Wajima city, Noto Japan.
