. The Common Starling Sturnus vulgaris is a winter visitor to Japan, with more records in the western region. In Hokkaido, this species is known as an accidental visitor, and some reports suggest that the number of observations recorded in the Sapporo region have recently increased. In this study, we first reported our observations of the starling in Oshima Peninsula, southern Hokkaido, where this species had not been previously recorded. We then collected published observation records from 1987, when the first starling was recorded in Hokkaido, until 2018. From these records we examined the distribution of observations of the starling and assessed whether the number of them flying to Hokkaido has increased during this period. The birds were widely observed in Hokkaido, with the number of records occurring more frequently in the Sapporo, Ishikari and Okhotsk regions. The number of observation re cords was high both in spring （ April ） and fall （ October ） , suggesting that the birds might visit Hokkaido during their migration. The annual number of observation records showed an in-creasing trend, which occurred every year from 2004. In addition, the number of birds per observation seemed to increase in recent years, but with high interannual variability. There-fore, careful attention should be paid to the changes in the number of starlings and their distribution throughout Japan, including Hokkaido.

The status of seabirds breeding on Daikoku Island, eastern Hokkaido, Japan, was updated. The number of nest burrows of Leach's Storm Petrel Oceanodroma leucorhoa was estimated using nest densities and areas of each habitat in 2014, and was 415,674; about half of the annual population estimates for 1972‒1994. The number of nest burrows of the Rhinoceros Auklet Cerorhinca monocerata was estimated similarly, and was 77,734; about 10 times the estimate for 1986. These population changes were due to changes of both nest density and area of habitats. The number of nests of the Slaty-backed Gull Larus schistisagus was directly counted, and was 5‒30 in 2014‒2018; less than 5% of that recorded annually from 1982‒1994 (3,500‒8,200 pairs). The number of nests of the Japanese Cormorant Phalacrocorax capillatus was counted directly and was 120‒245 in 2014‒2018, except 2016; similar to that seen in 1980‒2015 (172‒321 nests). Disturbance by White-tailed Eagles Haliaeetus albicilla was observed in the colonies of Slaty-backed Gulls and Japanese Cormorants.

. To study the moult of remiges and rectrices of the White-cheeked Starling Spodiopsar cineraceus , we collected 10,292 of these feathers at their communal roost in Kindai University Higashiosaka Campus, Higashiosaka City, Osaka Prefecture, central Japan, between 2008 and 2009. Feathers were identified as primaries （ P1 to P10 ） , secondaries （ S1 to S6 ） , tertials （ Te1 to Te3 ） and rectrices （ R1 to R6 ） , and as adult feathers or juvenile ones. The birds had begun moulting before we started sampling in 2008, while we ceased sampling before they completed moulting in 2009, as they were driven away from the roost. We collected their feathers between early June and the end of September, while they used the roost from late May through November. They started moulting from the innermost primary （ P1 ） to outer ones, from the outermost secondary （ S1 ） to the inner ones, and from the center tertials （ Te2 ） to the inner （ Te3 ） and then the outer ones （ Te1 ） . As rectrices were replaced from the central （ R1 ） but within a short period of time, the sequence of moult of rectrices was unclear. The moult sequences were the same for adult feathers and juvenile ones. Juvenile primary feathers were collected later in the season than adult ones. The inner primaries of adults, and the inner secondaries of both adult and juveniles, were relatively scarce. These observations indicate that adults shed their inner primaries before they formed the summer roost, and they suspend-ed the moulting of the inner secondaries in September, presumably because of pair formation in autumn. The collection of shed feathers under the roosting area could be simple and useful technique to study moult.

. We provide information on two early specimens of the Japanese Reed Bunting Emberiza yessoensis collected by Thomas Blakiston in Hokkaido in early Meiji times. One of these specimens was regarded as lost, but we rediscovered it. The other had become separated from its year and locality of collection. We have reunited the data with this specimen by analyzing Blakiston ʼ s notebook and specimen catalogue. We have also shown that one specimen, a potential type, was collected in Hakodate. These rediscoveries are of importance in determining the taxonomy of the Japanese Reed Bunting, for proving that these early specimens were truly the Japanese Reed Bunting, and for demonstrating its historical and current distribution and relationship to climate and weather.

. The first importation of live penguins to Japan took place when two Humboldt Penguins （ Spheniscus humboldti ） arrived in 1915 from Chile. One of them was donated to the Tokyo Imperial Household Museum Zoo （ which later became Ueno Zoological Gardens ） on June 9, 1915 by Mr. Isokichi Ozawa, the chief engineer of a Japanese merchant ship with regular service to South America. After its death it was preserved as a stuffed specimen, and its record was found in the specimen database （ Tensanbu Daicho ） of the Tokyo Imperial Household Museum. After the passing of this penguin, the other individual was purchased by Hanayashiki, an amusement park in the Asakusa district in Tokyo. In 1951, Mr. Haruo Takashima discovered the record for a specimen of the Humboldt Penguin registered by the same specimen number in the Tensanbu Daicho at the National Museum of Nature and Science; he later reported that it was an immature bird （ Takashima 1952a ） . It is now believed that the specimen of the immature Humboldt Penguin at the National Museum of Nature and Science, previously considered to be of unknown origin, was one of those first two living penguins imported into the country. In addition, I found that the penguin illustrated in a traditional Japanese hanging scroll was modeled after the individual kept at Hanayashiki and that it was also an immature bird. This has led this author to assume that immature penguins that were easy to keep, were chosen for shipment to Japan.

. Fault bars are narrow structural malformations in feathers. Procellariiform seabirds have long wings that generate lift and power at high speeds and short tails that may not provide dynamic stability. We predicted that Procellariiformes would have fewer fault bars in their wing feathers than in their tail feathers. We examined Laysan Albatrosses Phoebastria immutabilis （ bycatch in the Japanese pelagic longline fishery in the western north Pacific ） and compared the occurrence of fault bars between primary remiges and rectrices using hierarchical Bayesian models. As expected, the models suggested that albatross primary remiges had fewer fault bars than rectrices.
