Philippine Eagle-Owl
Ketupa philippensis
A large owl of lowland and foothill forest, including secondary habitat and plantations. Warm brown with a heavily marked back, a heavily streaked rufous head and chest, and a more sparsely streaked pale belly. Note the square-shaped head with flattened ear tufts and the yellow eyes. Unmistakable. No other owls of similar size occur in its range. Gives a long, drawn-out, spooky whistled note whose pitch rises slightly, then falls at the end.
识别特征
The Philippine eagle-owl has a total wingspan of about 48 inches, and with a total length of 40–50 cm (15.5–19.5 in) and a wing-length of about 35 cm (14 in), (where typically a female would size larger than a male) it is the largest owl in the Philippines, but among the smallest members of the genus Ketupa. It is overall rufous with a lighter belly and yellow eyes. It has a warm brown coloring with many markings on its back, with a bird call pitch of a long whistle that rises shortly and falls at the end. It is also described as being incredibly bulky and having tufted ears, closely resembling the buffy fish-owl (Ketupa ketupu). The subspecies K. p. mindanensis is darker and more heavily streaked than the nominate form.
分类信息
The Philippine eagle-owl was formally described in 1851 by the German naturalist Johann Jakob Kaup. He placed the owl in his new genus Pseudoptynx and coined the binomial name Pseudoptynx philippensi. The Philippine eagle-owl is now placed in the genus Ketupa that was introduced in 1831 by the French naturalist René Lesson.<p>Two subspecies are recognised:

行为
Little is known about the behavior of this secretive species, but the powerful feet suggest it feeds on small mammals and birds.<p>This eagle-owl lays one egg per clutch and has an incubation period of 35 days.<p>In December 2005, Negros Forests and Ecological Foundation (NFEFI) in Bacolod was the first conservation center in the world to successfully hatch a Philippine eagle-owl (aptly nicknamed Bubo) in captivity and it has the only breeding pair of these owls in captivity anywhere in the world.<p>On November 21, 2005, conservationists at the center made world history when it successfully bred a Philippine eagle-owl in captivity. Notably NFEFI had first secured the first-ever captive breeding loan between DENR-accredited institutions in the Philippines, consisting of three pairs of eagle-owls from the Avilon Montalban Zoological Park in Montalban, Rizal and transported them to Bacolod in December 2002. Two pairs showed attraction, and the couple Hinahon and Suplada—local terms for "calm" and "snob"—made courtship. It was on November 21, 2005, that an owlet was discovered in the nest, about three days old, and named Bubo. As Bubo grew, Suplada taught it how to tear pieces of mouse meat, thus rearing it.<p>In 2006, Suplada also laid one egg and another owlet was hatched through the aid[clarification needed] of the World Owl Trust, Flora and Fauna International-Philippine Biodiversity Conservation program and the Avilon Zoological Park in Montalban Rizal. The Philippine eagle-owl is also protected in areas through the Conservation of Priority Protected Areas Project (CPPAP) in Luzon, Mts Kitanglad and Apo on MIndanao.<p>Hunting of the Philippine eagle-owl is illegal in the Philippines, but lacks proper enforcement because many local people are able to resist strict control attempts.<p>After hatching, Philippine eagle-owl chicks need to be intensely cared for by their parents. These new chicks are unable to thermoregulate by themselves, so they need the body heat from their mother or father to keep them warm. These chicks are also unable to feed themselves due to their lack of ability to fly. The father bird will go out to catch the food while the mother will tear it up into smaller pieces for the chick to eat.

Plain Flowerpecker
Dicaeum minullum
Aptly named small songbird of lowlands, brownish-olive above, with pale, olive-washed underparts. Pale, unmarked face and large dark eye gives it a “cute” appearance. Lack of distinctive marks is itself distinctive; other flowerpeckers in range are streaked or have patches of bright color. Usually seen hovering around or probing into flowers; especially fond of mistletoe fruits and blossoms. Song is as plain as its appearance; a mid-length, descending series of high-pitched ticks. Also gives lower-pitched, more evenly-spaced ticks.
Santa Marta Wren
Troglodytes monticola
Highly endangered wren restricted to grassy and scrubby areas above tree line high up in Colombia’s Santa Marta Mountains. Reaching its habitat involves a multi-day camping expedition, and it cannot be seen in the commonly birded areas lower down the mountains. Rich coloration and heavily barred underparts separate it from House Wren, the only other similar species that could possibly occur in its lofty domain. Song is a descending, tinkling series of notes.
Slate-headed Tody-Flycatcher
Poecilotriccus sylvia
Very small, rather skulking flycatcher of dense tangles and thickets in humid tropical lowlands. Hops around like a sluggish warbler, often pausing motionless for long periods. Plumage is similar to many flycatchers—grayish head, olive upperparts with yellowish wing edgings, and pale yellowish belly—but note the rather long bill, pale eyes, habitat, and behavior. Similar Northern Bentbill favors more open forest understory, perches more upright, and has bent bill.
