Ryukyu Scops-Owl
Otus elegans
Diminutive brownish owl with short ear tufts and pale face narrowly bordered in black. Combination of overall brown coloration, yellow eyes, and small size distinguishes it from the larger Oriental and Japanese Scops-Owls. Like other scops-owls, often difficult to see; listen for its hiccuping hoots, given in a long series. Inhabits forests and adjacent edges throughout its range.

分布与栖息地
The distribution of the Otus elegans botelensis is restricted by the distribution of naturally occurring tree holes. The size of the holes is usually a diameter at breast height (dbh) of more than 38 cm. Different type of trees provides differing quantities of such holes for the Otus elegans botelensis. Observation had revealed that tree holes are more likely to form in Pometia pinnata compared to other types of tree, therefore, areas with lots of Pometia pinnata have greater densities of the Otus elegans botelensis.: 7 It is found on the Ryukyu Islands of southern Japan, on Lanyu Island off south-east Taiwan, and on the Batanes and Babuyan Islands off northern Luzon, Philippines, in tropical or subtropical evergreen forest. It is becoming rare due to habitat loss.

Caroline Islands Ground Dove
Pampusana kubaryi
Beautiful dark velvet dove with a pristine white face, throat, and breast. Endemic to Chuuk and Pohnpei, in the Caroline Islands group. Inhabits forested areas, including disturbed patches adjoining agriculture. Forages actively on or close to the ground. Unlike many other doves and pigeons, flushes more or less silently; typically flies only a short distance when flushed.
Gray-headed Albatross
Thalassarche chrysostoma
Rarely found north of cold subantarctic waters; ranges south to pack-ice in summer. Adult has a gray head, thick black underwing margins like much commoner Black-browed Albatross. Immatures look similar to Black-browed overall, but told by black bill that soon develops yellow along top, and often with variable gray hood. Yellow bill edges narrower than the more lightly built Buller’s Albatross, which occurs to the north but is often mistaken for Gray-headed.
Snowcap
Microchera albocoronata
Tiny hummingbird; male is unique and beautiful: his body is the color of red wine, and he has a bright white cap. Unmistakable in limited range. Female is less striking, but note small size, snowy white underparts, and short straight bill. Most often seen feeding at small purple flowers in gardens and forest edges
