Brown-eared Bulbul
Hypsipetes amaurotis
A large grayish songbird that shows considerable plumage variation throughout its range. Regularly found flocking in forested habitats as well as more open environments such as farmland and cities, where its loud vocalizations, long tail, and undulating flight make it conspicuous and distinctive. The Taiwan subspecies (harteri) is gray above, pale below, with chestnut extending from cheek to underparts, where it extends down the belly in streaks. Varied calls are loud and shrill.
识别特征
Reaching a length of about 28 cm (11 in), brown-eared bulbuls are grayish-brown, with brown cheeks (the "brown ears" of the common name) and a long tail. While they prefer forested areas, they readily adapt to urban and rural environments, and their noisy squeaking calls are a familiar sound in most areas of Japan. One author described the song of the brown-eared bulbul as "one of the most unattractive noises made by any bird".
分类信息
The brown-eared bulbul was originally described in the genus Turdus. Later, some authorities placed it in the genus Ixos and then the genus Microscelis, before being re-classified to Hypsipetes in 2010. Alternate names for the brown-eared bulbul include the Asian brown-eared bulbul, chestnut-eared bulbul, and Eurasian brown-eared bulbul.<p>Twelve subspecies are currently recognized:

分布与栖息地
The brown-eared bulbul is common in a very large range that includes the Russian Far East (including Sakhalin), northeastern China, the Korean Peninsula, and Japan, south to Taiwan and the Babuyan and Batanes island chains in the north of the Philippines.<p>Historically, brown-eared bulbuls were migratory birds moving to the southern parts of their range in winter, but they have taken advantage of changes in crops and farming practices in recent decades to overwinter in areas farther north than previously possible. Most brown-eared bulbuls still move south in winter, often forming huge flocks during migration. They are considered agricultural pests in some areas of Japan where they may invade orchards and damage crops such as cabbages, cauliflowers and spinach.

Sandwich Tern
Thalasseus sandvicensis
Pale medium-sized tern with a geographically variable bill pattern: black with a distinct yellow tip in most of its range; entirely yellow in the Caribbean and parts of South America. Shows a shaggy black cap in breeding plumage; nonbreeding birds develop white forehead. Strictly coastal; most commonly found on beaches and estuaries, often mixed with flocks of other terns. Harsh grating calls similar to other terns.
