Pallas's Grasshopper Warbler
Helopsaltes certhiola
Furtive streaky brown warbler; typically buries itself deep in tangled vegetation and is very difficult to see. If seen well, note well-streaked upperparts, long wedge-shaped tail, and rufous rump. Only other well-streaked Locustella warbler in range is the smaller Lanceolated, which has a shorter tail and more extensive streaking on the underparts. Favors wet habitats; breeds in boggy taiga and vegetated riverbanks, winters in reedbeds and marshy fields. Clattering song reminiscent of reed warblers. Call a sharp “tik”; also gives a rapid-fire dry rattle.
识别特征
This is a medium-sized warbler. The adult has a streaked brown back, whitish grey underparts, unstreaked except on the undertail. The sexes are identical, as with most warblers, but young birds are yellower below. Like most warblers, it is insectivorous. It is very similar to the common grasshopper warbler, but is slightly larger, has white tips to the tail and tertial feathers, and a warmer brown rump. The white tips are the reason for its colloquial, mnemonic name of "PG Tips".<p>This is a skulking species which is very difficult to see except sometimes when singing. It creeps through grass and low foliage.

分布与栖息地
This small passerine bird is found in tall grass with some thicker vegetation, usually close to water in bogs or wet meadows. From 4 to 7 eggs are laid in a nest on the ground in grass. This species is a very rare vagrant to western Europe. One of the best places to see this skulking species as a vagrant is Fair Isle, Shetland; for a species that only rarely appears in western Europe, it can be found there with some regularity.

Mottled Petrel
Pterodroma inexpectata
A medium-sized petrel with a distinctive dark patch on the belly. Slightly larger and heavier-bodied than Black-winged, Bonin, and Cook’s Petrels. Regularly seen offshore from boats and sometimes from shore.
Scissor-tailed Nightjar
Hydropsalis torquata
Boldly marked nightjar; streaked brown, gray, and buff above and barred brown below with a prominent rufous neck patch. Males have spectacular scissor-shaped tail extensions, dark on the outside, pale on the inside. Tail of females is short with no white. Fairly common in grasslands with scattered bushes and at forest edges.
Mongolian Accentor
Prunella koslowi
A very plain accentor of dry, open areas with sparse, scrubby vegetation. Patterning more closely resembles that of a lark or a pipit than another accentor: pale sandy brown all over with a paler belly and a finely streaked back. For an accentor, oddly shy and skulking, usually sticking to cover and infrequently vocalizing.
