Townsend's Storm-Petrel
Hydrobates socorroensis
Endangered seabird found in the Pacific Ocean well off the coast of Mexico and southern California. It breeds in summer on small islets near Guadalupe Island, located 160 miles from Baja California, and disperses northward and southward at other times of the year. Plumage is dark gray with a notched tail and pale stripes on the upperwing; rump may be either dark or white. Flies erratically and often patters the ocean with its feet. Very similar to Leach’s Storm-Petrel, which also has white- and dark-rumped forms, but it is smaller and darker with more rounded wings and less contrasting wing stripe. Also very similar to Ainley's Storm-Petrel, but keep in mind that Ainley’s has not yet been recorded in US waters.

Mistle Thrush
Turdus viscivorus
Rather large thrush, gray-brown above and whitish below with rather rounded dark spots; tail has small white corners, lacking in appreciably smaller Song Thrush. In flight, looks rather pale and grayish overall, especially when compared with dark brownish Song Thrush. Found in a variety of wooded habitats, including parks and moorland with hedges and taller trees. Often feeds on larger lawns and grassy verges, often well away from cover. Sweet and rich-sounding warbled song is similar to that of Eurasian Blackbird, and very unlike Song Thrush. Dry rattle calls are distinctive.

Spot-breasted Thornbird
Phacellodomus maculipectus
Shy understory bird of upper humid montane forest in the east slope of the Andes from central-western Argentina to central Bolivia. Prefers thick understory, and more often heard than seen. Often curious and inquisitive, but tends to stay hidden when possible. From similar Streak-fronted Thornbird by reddish cap, spotted underparts, and habitat (Streak-fronted prefers dryer and more open woodland). Song an accelerating then decelerating series of 10-12 “queet!” notes that rise and then fall in pitch.

Ochre-fronted Antpitta
Grallaricula ochraceifrons
Small, streaky antpitta found only in a small area of the eastern Andes in northern Peru. Note the strongly marked underparts and the white mustache. Male has a chestnut face and forehead; female lacks this and has a much thicker eye-ring. Inhabits the understory of epiphyte-laden cloud forest. Unlike most larger antpittas, it is usually seen on a low perch and only occasionally comes down to the ground. Visits a feeder in at least one private reserve. Song is a short, high-pitched whistle given about every 10 seconds.
