Green Racquet-tail
Prioniturus luconensis
A rare medium-sized parrot of lowland and foothill forest on Luzon. The two central tail feathers have extended shafts ending in a racket shape. Overall green in color, slightly darker on the back, with paler head and underparts and a pale bill. Male is more yellowish-green in color. Overlaps geographically with Luzon Racquet-tail, but Green is found at lower elevations and lacks the brownish back. Also overlaps with Blue-naped Parrot, but has a pale rather than red bill. Voice consists of ringing metallic squawks.

Ebird describes this bird as "A rare medium-sized parrot of lowland and foothill forest on Luzon. The two central tail feathers have extended shafts ending in a racket shape.

Voice consists of ringing metallic squawks.<p>They are sexually dimorphic. Males are entirely yellow-green, with paler underparts and head. The two central tail feathers are elongated with bare shafts and terminated with black rackets. Females are generally darker and less yellowish, while the bare tail shafts are shorter. Juveniles do not have rackets at the tail. Total length is about 29 centimeters.<p>Like all other Racket-tails, they are cavity nesters.

分布与栖息地
Green racket-tails can be found in the canopy of tropical lowland rainforests in elevations of up to 700 meters where it mainly prefers primary forest but is also seen in secondary forest and forest. They have also been recorded visiting cultivations to feed on crops.<p>It is listed as Endangered with the population being estimated at 1,000 - 2,499 individuals remaining. It has gone locally extinct in many of its former sites and is feared extinct on Marinduque. Its main threat is trapping for the cage-bird trade. Local extinctions as a direct result of forest loss are very likely. In 1988, forest cover was just 3% on Marinduque and 24% on Luzon with the remaining forest continuing to be threatened by both legal and illegal logging. mining, road construction, slash-and-burn or kaingin.<p>In its stronghold in Subic has experienced increased illegal logging and deforestation continues in Maria Aurora Memorial Natural Park. Interspecific competition is also a threat as they have been replaced by the commoner Blue-crowned racket-tail in Quezon National Forest Park.<p>It is currently known from two protected areas Bataan National Park and the Northern Sierra Madre Natural Park. It receives nominal protection in the Maria Aurora Memorial Natural Park. However, like most areas in the Philippines protection and enforcement is lax and deforestation and the cage-bird trade continue.<p>Conservation actions proposed include surveys to identify further sites supporting key populations, with a view to formally establishing them as protected areas. Research its ecology and year-round requirements, to improve understanding of its management needs. Examine trends in Racket-tail species at all sites to monitor the spread of the apparently invasive Blue-crowned racket-tail. Improve protection measures against logging at Subic Bay Forest Reserve. Clamp down on illegal logging within the species's range, and ensure that environmental impact assessments are carried out before any new logging concessions are granted. Establish a captive breeding population to support future reintroduction and supplementation efforts. Lobby against proposed developments that threaten suitable habitat.

Short-crested Coquette
Lophornis brachylophus
Tiny, scarce, and very local hummingbird restricted to humid forest and shade-coffee plantations in foothills of Sierra Madre del Sur, Guerrero. Feeds quietly at middle to high levels in flowering trees. Feeding flight is slow and insectlike, flying with tail cocked and showing off big white to buffy-white band across lower back—easily passed off as a big bee or moth. Male has short, spiky orange crest, green throat, and rusty tail sides. Female rather drab, with dull orange forehead, and dingy whitish underparts.
Harlequin Quail
Coturnix delegorguei
Small ground-dwelling bird. Male has a bold and beautiful pattern; female is plain brown. Found in habitats with thick ground cover, such as grasslands and crop fields. Shy and inconspicuous; usually seen when flushing from thick cover. Most often detected by voice, a three-part whistle in which a longer first “whit” note is followed by two quicker “whit” notes. Male is distinctive, but female is extremely similar to Common Quail, especially when seen only in flight. If seen well, female Harlequin Quail is darker and more uniform, without a bright white belly or bold streaking on the back. Females also similar to buttonquail, but with duller and less complex patterning. When flushed, Harlequin Quail also has stronger and more direct flight than buttonquail.
Magpie-lark
Grallina cyanoleuca
Large, terrestrial songbird with long, strong legs and fairly long, thin bill. Male black above, white below, with white wing patch, white face patch, white eye, black bib, black eyeline; female has white throat and immature a dark eye. Inhabits parks, gardens, and urban areas. Aggressive and noisy, often attacking its own reflection in car mirrors and windows. Much smaller than Australian Magpie, with a smaller pale bill.
