During bird-banding operation of 1-5, May 1981, on Awashima, 63km north of Niigata City, the following rare species and subspecies were obtained.
1. Dupetor flavicollis Band No. 090-89101, May 4. First record for Japan.
2. Emberiza chrysophrys Three examples: Band Nos. 022-75873, 022-75874 (May 3), 030-60576 (May 4). So far considered as straggler, but may be a winter migrant in small numbers.
3. Emberiza tristrami Three examples: Band Nos. 022-75964 (May 4), 022-75994, 030-60579 (May 5). Also to be classed as rare winter visitor.
4. Emberiza spodocephala spodocephala Continental race spodocephala. Three examples: Band Nos. 022-75911, 022-75978 (May 4), 010-21429 (May 5). This race has been known by very few specimens from Japan proper.
5. Emberiza pusilla Two examples: Band Nos. 010-21419 (May 4), 010-21427 (May 5). This species may also to be called an uncommon winter visitor.
6. Emberiza aureola Band No. 022-75921 (May 4). A common summer breeder in Hokkaido, but very rarely occurs in Honshu, a new record for Niigata. A female was also observed.
7. Emberiza rutila Not banded, but observed and photographed (May 4), as new record for Niigata.
Additional notes: A Locustella fasciolata when banded and being photographed, began to sing in the hand (Though it was quite different from its tipical song), Breeding of Falco peregrinus on Awashima was suggestive from its circling alarm flight (Formerly had been breeding until 1964).
