Stejneger's Petrel
Pterodroma longirostris
Medium-sized, elegant seabird of the deep Pacific Ocean, rare in Japanese waters. Grayish above, white below, with dark “M” pattern in upperparts. White forehead extensive; dark gray crown stands out against lighter gray back and often terminated by a sharp white “notch” of plumage. Underwing mostly white, with only small black marks at the “wrists,” unlike many other gadfly petrels, and tip of tail extensively black, unlike rather similar Cook’s and Masatierra Petrels.

Gray Flycatcher
Empidonax wrightii
Drab, pale-gray flycatcher with little plumage contrast; very similar to other flycatchers, especially Dusky and Hammond's. Often best identified by unique habit of wagging tail downward. Breeding habitat also distinctive: lower, more open habitat than other flycatchers, usually in sagebrush or open juniper forest. In migration and winter, habitat overlaps more with other flycatchers, but still tends to prefer more open areas. Other subtle differences in appearance include shorter wingtips, longer bill, and paler plumage. Song includes hoarse "chivik" phrase and higher, clearer "pseeoo." Call similar to Dusky. Without an excellent view, sometimes best left unidentified.

Black-chinned Siskin
Spinus barbatus
Fairly common in lowlands and foothills (rarely at higher elevations), where it is found in town parks, gardens, matorral, woodland, and open and semiopen areas with bushes. Spirited bubbling and warbling song can be prolonged and draw attention, but often given from concealed perch in the tree canopy. Like other siskins, often in flocks, especially in nonbreeding season. Male is yellow overall with messy blackish cap and chin patch. Female is a rather drab grayish or yellowish overall, but note distinctive yellow wing patches. Compare with Grassland Yellow-Finch, which often occurs in same areas.

Semipalmated Plover
Charadrius semipalmatus
Small, orange-legged plover with solid dark breast band. Medium-brown upperparts are the color of wet sand, noticeably darker than Piping or Snowy Plovers. Look for short, blunt bill with orange base (often indistinct on juveniles). Feeds on mudflats and beaches, often mixed with other shorebirds. Even when in a flock, individuals are typically spread out rather than remaining a tight unit. Breeds on the tundra or rocky beaches at northern latitudes; winters to southern South America. Migrants are common and widespread, inland and coastal. Listen for distinctive two parted “chu-weep!” calls, and assorted chortles and chuckles.
