Attested from at least the 13th century. Origin is uncertain. One theory suggests shortening from an earlier 小雀目 (kogarame), meaning roughly “small birds that fly in a flock”. Others suggest shortening from 小山潜群, which in turn is from 小(こ) (ko-, “small”) plus 山潜群 (yamakugurimure), an obsolete form of 山雀(やまがら) (yamagara, “varied tit”). Compare also 烏帽子雀(エボシガラ) (eboshigara, “tufted titmouse”), 四十雀(しじゅうから) (shijūkara, “Japanese tit”).
