Rufous-headed Ground-Roller
Atelornis crossleyi
Chunky, long-legged, richly colored bird. White shoulder marks are conspicuous in flight. Elusive and shy; unlikely to be seen by those not searching for it. Found in eastern rainforest, at upper and middle elevations. Feeds in the understory, usually in thick areas, often with bamboo. Avoids disturbance by fleeing on the ground or making short flights. Song is a quick hollow “kwowp” note that is repeated slowly, delivered from a low perch, often a mossy log. Lacks the intricate scaly marks of Scaly Ground-Roller and the pale underparts and complex head pattern of Pitta-like Ground-Roller.
识别特征
The sexes are similar in this distinctively-coloured bird about 25 cm (10 in) long. The head and breast are reddish-brown, the upper parts olive green and the underparts buff with darker markings. There is a narrow blackish collar with white vertical streaks on the upper breast and an iridescent light blue patch on the carpal wing joint. The tail is short and the beak and legs are grey.

分布与栖息地
The rufous-headed ground roller is endemic to eastern Madagascar where it is found in montane evergreen rain forests at altitudes between 800 and 2,000 m (2,600 and 6,600 ft), but is most common between 1,250 and 1,750 m (4,100 and 5,700 ft). Although present in most mountain regions, it is absent from Montagne d'Ambre in the far north of the island.

行为
The rufous-headed ground roller is terrestrial and feeds amongst dense vegetation on the ground, taking a range of prey, particularly insects such as ants, beetles and their larvae, caterpillars, butterflies and cockroaches. It nests in a burrow up to 50 cm (20 in) deep in an earth bank. Breeding probably takes place in December and January, and the clutch size is normally two eggs.

Star Finch
Emblema ruficauda
Bright green finch with brilliant red face and bill and numerous small pale spots on face, chest, flanks, and base of tail. Compare longer-tailed female Crimson Finch, which is much browner and less heavily spotted. Often found in very large flocks in grasslands and reedbeds of northeastern Western Australia and northwestern Northern Territory; rarer in Darwin/Kakadu region.

Maui Parrotbill
Pseudonestor xanthophrys
A very rare Hawaiian honeycreeper of high elevation wet forests on eastern Maui. The thick, parrotlike bill used to tear and crush stems in search of insects and larvae is diagnostic. Most often seen in the understory moving slowly and deliberately among branches. Song is series of paired notes: “chewy-chewy-chewy.” Two-note “chu-wee” call is louder and lower pitched than that of ‘amakihi.

California Gull
Larus californicus
Medium-sized gull, a bit larger than Ring-billed Gull and smaller than Herring Gull. Adults have medium-gray upperparts (slightly darker than Herring Gull), and red and black markings on the bill. Takes four years for immatures to progress from mostly brown to fully white and gray adult plumage; intermediate plumages are often mottled and messy. Many immatures show a pink bill with a contrasting black tip, and dull pinkish or greenish-gray legs. Always note dark eye. Common and fairly widespread in western North America, inland and along the coast. Can be found at parking lots, beaches, or lakes, often in flocks with Herring and Ring-billed Gulls.
