Biology

provided by Arkive
It has been argued that the Philippine eagle-owl's striking resemblance to the Asian fishing owls (Ketupa spp.), and the fact that it is seemingly always found near water, suggests that at least some of its prey is likely to be hunted from rivers and lakes (6). However, the bird's large and powerful feet are more reminiscent of species that feed on small mammals and birds (5) (6), and more research is certainly needed to better understand this owl. No breeding information is as yet available except that an immature was collected in May and young birds were seen in April 1993 at an unspecified locality (6).

Conservation

provided by Arkive
The Philippine eagle-owl is known from several protected areas (2), including three CPPAP sites (Conservation of Priority Protected Areas Project): Northern Sierra Madre Natural Park on Luzon, and Mts Kitanglad and Apo on Mindanao (6). Aside from these areas, the species is known from two "key sites" (Central Catanduanes and Angat Watershed on Luzon) that, it has been advocated, deserve formal designation as protected areas (6). However, protection measures in existing 'protected areas' also need to be improved in accordance with their official protected status, such as at the U. P. Laguna Land Grant, which currently lacks full protection (6). Hunting of all bird species is illegal in the Philippines, but enforcement is lacking or inadequate and local people in many areas are likely to resist attempts at strict control (7). In the mid-1990s, the bird featured on a bilingual environmental awareness poster focusing on owls as part of the "Only in the Philippines" series (2) (6). However, concerted education and awareness programmes are still needed within the communities in and around key sites, to demonstrate the effects of hunting on the threatened birds (7). The Philippine eagle-owl has become the 'flagship species' for the Philippine Owl Conservation Programme (POCP), which was set up by the World Owl Trust (WOT) (working alongside the UK Owl Taxon Advisory Group and in partnership with the Philippine Government) to help ensure the survival of endangered endemic owl species and their habitats (8). The WOT has made considerable efforts to set up captive-breeding programmes for the eagle-owl (8) and, finally, in December 2005, the Negros Forests and Ecological Foundation Inc. (NFEFI) announced that a Philippine eagle-owl had successfully hatched in captivity (9). The breeding of this poorly understood eagle-owl at NFEFI is the world's first and only successful breeding of the species in captivity, and provides new hope for the conservation, propagation and ultimately the survival of this rare, endemic bird for the future (9).

Description

provided by Arkive
Endemic to the Philippines, this eagle-owl is one of the largest owls in the world, with an impressive wingspan of around 120 centimetres (3). The plumage is predominantly rufous coloured, and this eagle-owl is characterised by small, outward-slanting ear tufts and huge yellow eyes (2) (5). The facial disc is rufous-buff, the upper throat is buff, and the head, breast and upperparts are a tawny-rufous with conspicuous dark brown streaks (5). The wings and tail are barred dark-brown and rufous-buff, while the lower breast and belly are whitish with bold dark streaks (5). Calls involve a long series of bububububub sounds, fading away at the end, and high-pitched screams (2).

Threats

provided by Arkive
This species' population is small, fragmented, and undergoing a rapid decline due to extensive lowland deforestation throughout its range and possibly hunting (2). By the end of the nineteenth century large areas of the Philippines' forest had already been cleared for agricultural expansion, which continued throughout the twentieth century (7). However, the most extensive and rapid deforestation in the latter half of the century has been caused by commercial logging that has particularly impacted primary lowland forests, which shrunk from an estimated 10 million hectares in the 1950s to only one million by the late 1980s (7). A substantial proportion of remaining lowland forest in the Philippines is leased to logging concessions, and mining applications pose an additional threat (2). Typhoons on Catanduanes in 1987 and 1996 also destroyed large areas of forest (2). With relatively little habitat remaining below 1,000 metres (6) there is now considerable concern for this eagle-owl, whose large size requires large tracts of forest to maintain populations (3). Hunting is a major problem in the Philippines, with firearms widely available and 40 percent of the country's threatened birds currently affected (7). The impact of hunting on the Philippine eagle-owl is not known, but could be significant (6).

Streifenuhu ( German )

provided by wikipedia DE

Der Streifenuhu (Bubo philippensis), auch Philippinenuhu genannt, ist eine Art aus der Familie der eigentlichen Eulen. Er kommt ausschließlich in Südostasien vor. Es handelt sich um eine verhältnismäßig seltene Art, die als gefährdet eingestuft wird.[1]

Merkmale

Mit einer Körpergröße von 40 bis 43 Zentimetern ist der Streifenuhu eine verhältnismäßig kleine Uhuart.[1] Er hat kurze, etwas nach außen geneigte Federohren. Die Körperoberseite ist braunrötlich bis dunkelbraun mit schwarzen Längsstreifen. Der Schwanz ist dumpf rotbraun mit einem dunklen Querstreifen. Das Kinn ist blass rötlich, die Kehle weißlich. Der Rest der Körperunterseite ist blass rötlichbraun mit dunklen, braunen Streifen. Die Läufe sind befiedert. Der Schnabel ist verhältnismäßig groß. In seinem Verbreitungsgebiet ist der Streifenuhu nur mit der Mindanao-Zwergohreule zu verwechseln. Diese ist allerdings rötlicher gefärbt und auf der Brust und den Flanken finden sich sehr breite Streifen.

Verbreitung und Lebensraum

Das Verbreitungsgebiet beschränkt sich auf die Philippinen. Hier kommt der Streifenuhu auf den Inseln Luzon, Catanduanes, Mindanao, Samar und Leyte vor. Er ist ein Standvogel. Sein Lebensraum sind Wälder in der Nähe von Flüssen und Seen. Er hält sich in der Regel nur in den Tiefebenen auf.

Lebensweise

Der Streifenuhu ist eine weitgehend unerforschte Art. Weder seine Lebensweise noch seine Fortpflanzungsbiologie sind bislang erforscht. Auch über sein Nahrungsspektrum ist nichts bekannt. Beine und Füße sowie der sehr kräftige Schnabel legen nahe, dass er überwiegend kleine Säuger und Vögel frisst.

Bestand und Gefährdung

Der Bestand des Streifenuhus wird auf ca. 2.500–10.000 erwachsene Tiere geschätzt. Die Gefährdung des Uhus wird durch die zunehmende Fragmentierung des Lebensraums durch illegalen Holzeinschlag und die weitverbreiteten Brandrodungen verursacht. So ist in der Sierra Madre (Luzon) der Waldbestand um 83 %, auf Mindanao um 29 % zurückgegangen, so dass die Bestände zunehmend auf die Schutzzonen zurückgedrängt werden. So wurden Bestände des Streifenuhus in den Nationalparks und Naturschutzgebieten Mount Kitanglad Range Natural Park, Bulusan Volcano National Park, Northern Sierra Madre Natural Park, Mount Apo Natural Park, Angat Watershed Forest Reserve, Catanduanes Watershed Forest Reserve, Mounts-Banahaw-San-Cristobal-Nationalpark, Rajah Sikatuna Protected Landscape, Kalbario-Patapat National Park, Mounts Palay-Palay-Mataas Na Gulod National Park erfasst.

Philippine eagle-owl

provided by wikipedia EN

The Philippine eagle-owl (Ketupa philippensis) is a vulnerable species of owl belonging to the family Strigidae. It is endemic to the Philippines, where it is found in lowland forests on the islands of Catanduanes, Samar, Bohol, Mindanao, Luzon, Leyte and possibly Sibuyan.[3] The Philippine eagle-owl feeds on rodents and amphibians.[4] Due to its reliance on living in large lowland forests, forest conservation is important in order to maintain populations of the Philippine eagle-owl, which is becoming increasingly vulnerable to going extinct.[5] The Philippine eagle-owl was previously listed as endangered, but due to destruction of lowland habitat and possible hunting, the eagle-owl has since been adjusted to the vulnerability of extinction.[6]

Taxonomy

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.[7][8] The Philippine eagle-owl is now placed in the genus Ketupa that was introduced in 1831 by the French naturalist René Lesson.[9][10]

Two subspecies are recognised:[10]

Description

At Malagos Garden Resort, Davao City, Philippines

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.[11][12][13] 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.[14] It is also described as being incredibly bulky and having tufted ears, closely resembling the buffy fish-owl (Ketupa ketupu).[15] The subspecies K. p. mindanensis is darker and more heavily streaked than the nominate form.[12]

Habitat

This owl inhabits forest edges near streams. They rest in a tree during the day and hunts hunt at dusk to feed on small vertebrates. The Philippine eagle-owl is the largest owl in the country.[16]

Behavior

Little is known about the behavior of this secretive species, but the powerful feet suggest it feeds on small mammals and birds.[12]

This eagle-owl lays one egg per clutch and has an incubation period of 35 days.[17]

Breeding in captivity

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.

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.

In 2006, Suplada also laid one egg and another owlet was hatched through the aid of the World Owl Trust, Flora and Fauna International-Philippine Biodiversity Conservation program and the Avilon Zoological Park in Montalban Rizal.[18] 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.[19]

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.[19]

Early life

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.[20] 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.[21]

Threats

The Philippine eagle-owl has faced threats from several factors within its habitat. Some of those factors include deforestation for agricultural use, commercial logging, and natural causes that destroy the bird's habitat such as catanduanes and typhoons. Another factor that was contributing to the near extinction of these birds was illegal hunting and lack of enforcing the laws.[19] In the Philippines, some law enforcement agencies have poor management and internal corruption.[22] This corruption contributes to the long surviving issue of poaching and illegal trading of animals.[23] Interbreeding has also threatened the eagle-owl since it produces offspring that are infertile and unable to produce.[24]

Bubo philippensis ( Spanish; Castilian )

provided by wikipedia ES

El búho filipino (Bubo philippensis) es una especie vulnerable de búho perteneciente a la familia Strigidae. Es endémico de Filipinas, donde se encuentra en bosques tropicales en las islas de Catanduanes, Samar, Bohol, Mindanao, Luzón, Leyte y posiblemente Sibuyan. Es conocido localmente como el kuwago o bukaw.

Taxonomía

Hubo un tiempo en que estuvo clasificado en su propio género, Pseudoptynx. No se le conocen especies relacionadas. Se conocen dos subespecies:

Descripción

Con una longitud total de 40–50 cm y una longitud de ala de aproximadamente 35 cm, es el búho más grande de Filipinas, pero de los miembros más pequeños del género Bubo. El dorso, la cola y las alas son de color marrón rojizo con plumas negras y beige salpicadas por el plumaje. La cabeza y el pecho son de color castaño anaranjado y moteado de plumas negras; mientras que el abdomen es de color beige o blanco con plumas pardas y negras aquí y allá. Las plumas que tiene justo encima de los ojos son negras y hace que parezca que tiene cejas. El pico es curvado y grande, los ojos son de color amarillo. Ambas subespecies son parecidas pero mindanensis es más oscura.

Distribución y hábitat

Esta especie es endémica de Filipinas donde vive en las islas de Sámar, Leyte, Mindanao, Luzón, Catanduanes y Bohol.

Su hábitat principal son los bosques tropicales que cubren la práctica totalidad de Filipinas. Parece ser que prefiere vivir cerca de masas de agua como ríos, arroyos y humedales.

Comportamiento

Se conoce muy poco sobre el comportamiento en libertad de esta especie y la mayoría de los datos sobre su biología provienen de ejemplares criados en cautividad. Se intuye que es un animal de hábitos nocturnos como otras especies de búho.

No se sabe con certeza en que consiste su dieta pero su tendencia a vivir cerca de fuentes de agua sugiera que los peces forman parte de ella; por otra parte las características de sus garras y patas hacen pesar que aves y mamíferos también forma parte de su alimentación.

Tampoco se conoce sus hábitos reproductivos. Los ejemplares en cautividad ponen un huevo por nidada y el periodo de incubación dura 35 días.

Conservación

El búho filipino está catalogado como vulnerable por la UICN. Las poblaciones de esta especie son pequeñas y están fragmentadas entre sí lo que dificulta su supervivencia; y por ello, tiene una tendencia decreciente. Se encuentra amenazado por la destrucción de su hábitat, que está llevando a la deforestación a gran escala de los bosques en Filipinas, y la caza ilegal. Se estima que las poblaciones actuales rondan entre los 2.500 y los 10 000 ejemplares.

Filippiinienhuuhkaja (Bubo philippensis) on uhanalainen pöllöjen heimoon kuuluva lintu. Se on kotoperäinen Filippiineillä, missä sitä tavataan alavilla metsämailla useilla saarilla: Catanduanes, Samar, Bohol, Mindanao, Leyte ja ehkä Sibuyan.[1] Siitä käytetään paikallisesti nimityksiä "kuwago" ja "bukao".

Linnun pituus on 40–50 cm, siipienväli noin 35 cm, ja se on suurin Filippiineillä tavattava pöllö, mutta kuuluu huuhkajien suvun pienimpiin. Se on pääosin punaruskea, mutta vatsapuoli on vaaleampi. Sen silmät ovat keltaiset. Sillä on pienet korvatupsut.

Filippiinienhuuhkajan elinpiiriä ovat subtrooppiset ja trooppiset alavat metsät[1] jokien lähellä. Linnut oleilevat päiväsaikaan puussa, ja ne saalistavat hämärässä pieniä selkärankaisia.[3]

Alalajit

Sillä on kaksi alalajia:[2]

  • Bubo philippensis mindanensis (Ogilvie-Grant, 1906)
  • Bubo philippensis philippensis (Kaup, 1851)

Филиппинский филин[1] (лат. Bubo philippensis) — вид птиц рода филины, обитающий в Юго-Восточной Азии. Эндемик Филиппин.

Описание

Это крупный филин высотой 40—50 см и длиной крыла в 35 см. Имеет рыжеватое оперение, светлый живот и жёлтые глаза. Обитают только на Филиппинах в лесах вблизи рек и озёр. О репродуктивной биологии этих птиц известно немного. Откладывают только одно яйцо. Инкубационный период длится примерно 35 дней. Вырубка лесов и ограниченный ареал являются причиной классификации Международным союзом охраны природы этого вида как «Находящимся в уязвимом положении» (Vulnerable)[2].

Описаны два подвида:
