Marbled Frogmouth
Podargus ocellatus
Large, nocturnal bird with very wide "frog-like" bill, an inhabitant of rainforest habitats. Compared to similar Tawny Frogmouth (often found in urban and suburban areas), Marbled has longer tail in proportion to its body, longer barred tufts above the bill, and a more blobby or marbled pattern on the underparts. Unusual call is a descending, turkey-like gobble, followed by a loud snap of the bill.
识别特征
The marbled frogmouth (Podargus ocellatus) is a bird in the family Podargidae. The species was first described by Jean René Constant Quoy and Joseph Paul Gaimard in 1830. It is found in the Aru Islands, New Guinea and Queensland. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.
分类信息
There are five subspecies recognised; the nominate ocellatus is found in New Guinea and surrounding islands. Two subspecies are found on islands of Papua New Guinea; intermedius is found on Trobriand Islands and D'Entrecasteaux Islands, meeki is endemic to Tagula Island. Australia has two subspecies; marmoratus is found on Cape York Peninsula, plumiferus (known locally as the plumed frogmouth) is found in south-east Queensland.<p>Rigidipenna inexpectatus, endemic to four islands in the Solomon Islands, was formerly considered a subspecies. It was split into its own genus, Rigidipenna, in 2007.

分布与栖息地
The Conondale ranges in Queensland's Sunshine Coast is considered a stronghold for the plumed frogmouth; notable populations are within the Conondale National Park. The species is rare and is listed as vulnerable in Queensland and occurs in subtropical rainforest and vineforest at altitudes from 50–800 m. The species roosts in the canopy of and is considered cryptic and extremely hard to find or study. Current populations are threatened by land clearing, inappropriate fire regimes and timber harvesting with future impacts of climate change posing additional risks. There have been estimates of the current pairs in the Conondale ranges being around 800 pairs with the current range of the species is just under 2000 ha with some potential future habitat increase in population being created by regenerating rainforest previously logged. Its specialised habitat requirements being un-logged pristine forests, the species is considered extremely vulnerable due to significant habitat reduction. Future harvesting of native timber in the Conondale region also poses risk.

Bearded Wood-Partridge
Dendrortyx barbatus
Very elusive, chickenlike bird of humid evergreen forest in foothills and highlands; scarce and very local in eastern Mexico where it is endemic. Usually in pairs or small groups on the forest floor. May be seen beside quiet trails and roads early and late in the day; runs away quickly and rarely flies. Note the blue-gray face and throat, red bill and eyering, and rusty breast. Loud rollicking songs are given mainly early and late in the day and most often reveal its presence.
Yellow-eyed Junco
Junco phaeonotus
This distinctive sparrow is common in open montane woodland usually dominated by pine. Primarily a Mexican species, barely enters U.S. Much like Gray-headed and Red-backed subspecies of Dark-eyed Junco but with staring yellow eye and rufous back usually extending onto wings. Otherwise pale gray, darkest around the eye. Bill half black, half yellow. White outer tail feathers like Dark-eyed Junco. Forages on the ground, but perches higher when singing. Song has a similar ringing tone to Dark-eyed Junco, but usually with several distinct sections of chips and trills.
Rufous-chested Dotterel
Zonibyx modestus
A handsome, distinctive, and medium-sized plover that breeds on southern moorland and steppe, and migrates north to winter on beaches and coastal flats. Found mainly in pairs and small loose groups in summer, but migrant and winter flocks can be a few hundred birds. Adult is distinctive, with bold white eyebrow, and plain brown upperparts. Breeding birds have a bright rusty breast above a broad black band. Nonbreeding birds are duller with a muted breast pattern. Juvenile has buffy eyebrow and fine pale spangling above, but looks like adult by mid-winter.
