    We had the chance to observe an adult and a juvenile Black-legged Kittiwake Rissa tridactyla that were unable to fly. The adult bird was picked up alive on the beach near Fushoji, Kanazawa-shi, Ishikawa prefecture. This bird was taken to Ishikawa Bird Obsarvatory and was fed with small fish but couldn't be released. The juvenile bird, captured at Sodegaura-machi, Chiba prefecture on 26th November 1988, was ringed (Ring No. 080-07197) and released at Chiba port, Chiba-shi on 5th December 1988.
    Wing and head plumage, together with bill shape and hind toe structure showed these birds identifiable as Rissa tridactyla pollicallis.

    83 Japanese Wagtails Motacilla grandis were banded and measured at Toki River, Ranzan-machi and Higashimatsuyama-shi, Saitama prefecture, from October 1988 to January 1989.
    Research showed that remiges, the outermost alula and primary coverts differ between sex and age classes. These are shown in figs. 1, 2 and table 2. The differences in measurements between sex and age classes are shown in table 1.
