Negros Bleeding-heart
Gallicolumba keayi
A very rare medium-sized ground dove of foothill forest floor on Negros and Panay. Iridescent greenish-blue on the head and sides to the chest, scaled on the upper back, with brownish flight feathers. White underparts narrow from the throat down the chest to the belly. Obvious white crescents mark the wing and sides of the chest. Note the red “bleeding heart” in the center of the chest. Unlikely to be mistaken if seen well. The only other dove likely to flush from the ground would be Asian Emerald Dove. Song is a short, accelerating series of low notes.

Ebird describes it as "A very rare medium-sized ground dove of foothill forest floor on Negros and Panay.

Ground-feeder but roosts and nests on bushes or vines; seen in pairs in a flock. Birds with enlarged gonads recorded in April and May and a recent fledgling obtained on May 3.<p>It has been recorded nesting in March - June with chicks fledging after only 12 days, apparently as an adaptation to the vulnerability of their open and low nests in epiphytic ferns. Nests appear to be regularly predated. The species predominantly feeds on plant material, although there is some potential evidence to suggest that they may also occasionally feed on ground invertebrates.

分布与栖息地
The Negros bleeding-heart lives primarily in primary forest up to 1,200 meters above sea level. They are sensitive to habitat disturbance and do not tolerate second growth as well but there are some sparse records..<p>It is critically endangered with the population estimated to be 50 -249 mature individuals remaining. They are threatened by hunting for food, trapping for the pet trade and habitat loss . Continuing rates of forest loss on the two islands where it occurs suggest that it will continue to decline. By 2007, Negros and Panay had a 3% and 6% remaining forest cover with most of this being higher elevation forest where this bird does not thrive in. Despite already paltry forest cover, deforestation still continues thanks to both legal and illegal logging, conversion into farmland, mining and road development. Trapping and hunting for food and, presumably, for the cage-bird trade constitute other threats.<p>It was bred for the first time in captivity in 2007 at the Center for Tropical Conservation Studies. As of 2013, the captive population totals 18 individuals, 14 of which have been bred from birds confiscated from the illegal bird trade. Captive breeding is being undertaken by the Talarak Foundation supported by the Philippines Biodiversity Conservation Foundation. There are plans for future reintroductions.<p>Conservation actions proposed include fieldwork and surveys in areas where they have been reported and other areas with suitable habitats. Provide protection for existing habitats like the Northern Negros Forest reserve. Encourage reforestation activities with an emphasis on native trees. Create education and awareness campaigns to aid in conservation and prevent hunting and the pet trade.

Andaman Coucal
Centropus andamanensis
A large, pale-brown, ground-dwelling cuckoo with rusty wings and back. Skulks in bushes and low cover, where it moves clumsily as it searches for small invertebrates, small mammals, and birds to prey on. Like other coucals, it is a cuckoo that builds its own nest. Common throughout its range in gardens, groves, disturbed forests, paddyfields, etc. The song is a series of deep and resonant “hoop” notes.
Lava Gull
Leucophaeus fuliginosus
Distinctive gull endemic to Galápagos. Adult is easy to identify by sooty-gray body, black head, white crescents above and below eye, and pale rump. Juvenile is grayish brown with tan scaling on the back and wings, and a pale rump. Found along the coast, almost never venturing inland or very far out to sea. Forages along beaches and rocky shorelines, and often perches on boats and docks. It has the smallest population of any gull in the world, estimated at less than 1000 birds.
Purple-backed Fairywren
Malurus assimilis
A small bird with a very long blue tail that is held cocked. Breeding male has a bright pale-blue helmet, black breast, purple back, and chestnut shoulders. Small pale tips are sometimes visible on the tail. Over much of the species’s inland range, females are overall grayish birds with pale fronts and long blue tails; however, females of the subspecies found in the sandstone regions of the Kimberley and Arnhem Land have contrasting blue crowns and backs. This species occurs over much of arid inland Australia and is found in open vegetation.
