Davao’s Famous Symbols

Philippine Eagle(Pithecophaga jefferyi), also known as the Monkey-eating Eagle, is an eagle of the family Accipitridae that is endemic to forests in the Philippines. It has brown and white-coloured plumage, and a shaggy crest, and generally measures 86 to 102 centimetres (2.82 to 3.35 ft) in length and weighs 4.7 to 8 kilograms (10 to 18 lb). Among the rarest, largest, and most powerful birds in the world, it has been declared the Philippine national bird. It is critically endangered, mainly due to massive loss of habitat due to deforestation in most of its range. Killing a Philippine Eagle is punishable under Philippine law by twelve years in jail and heavy fines.

Philippine National Eagle

The first European to discover the species in 1896 was the English explorer and naturalist John Whitehead, who observed the bird and whose servant, Juan, collected the first specimen a few weeks later. The skin of the bird was sent to William Robert Ogilvie-Grant in London in 1896, which initially showed it off in a local restaurant and described the species a few weeks later.

Upon its discovery, the Philippine Eagle was first called the monkey-eating eagle because of reports from natives of Bonga, Samar, where the species was first discovered, that it preyed exclusively on monkeys; from these reports it gained its generic name, from the Greek pithecus ("ape or monkey") and phagus ("eater of"). The specific name commemorates Jeffery Whitehead, the father of John Whitehead. Later studies revealed, however, that the alleged monkey-eating eagle also ate other animals such as colugo, civets, large snakes, monitor lizards, and even large birds like hornbills. This coupled with the fact that the same name applied to the African Crowned Eagle and the Central and South American Harpy Eagle, resulted in a presidential proclamation to change its name to Philippine Eagle in 1978, and in 1995 was declared a national emblem. This species has no recognized subspecies.

Apart from Philippine Eagle and Monkey-eating Eagle, it has also been called the Great Philippine Eagle. It has numerous local names, including agila ("eagle"), haribon, haring ibon ("bird king") and banog ("kite").

The Philippine Eagle is endemic to the Philippines and can be found on four major islands: eastern Luzon, Samar, Leyte and Mindanao. The largest number of eagles reside on Mindanao, with between 82 and 233 breeding pairs. Only six pairs are found on Samar, two on Leyte, and a few on Luzon. It can be found in Northern Sierra Madre National Park on Luzon and Mount Apo and Mount Kitanglad National Parks on Mindanao.

This eagle is found in dipterocarp and mid-montane forests, particularly in steep areas. Its elevation ranges from the lowlands to mountains of over 1,800 metres (5,900 ft). It is estimated that only 9,220 square kilometers (2,280,000 acres) of old growth forest remains in the bird's range. However, its total estimated range is about 146,000 square kilometers (56,000 sq mi) (Wikipedia, 2014).

Durian. Is the fruit of several tree species belonging to the genus Durio and the Malvaceae family (although some taxonomists place Durio in a distinct family, Durionaceae).

Widely known and revered in Southeast Asia as the "king of fruits", the durian is distinctive for its large size, unique odour, and formidable thorn-covered husk. The fruit can grow as large as 30 centimetres (12 in) long and 15 centimetres (6 in) in diameter, and it typically weighs one to three kilograms (2 to 7 lb). Its shape ranges from oblong to round, the colour of its husk green to brown, and its flesh pale yellow to red, depending on the species.


The edible flesh emits a distinctive odour, strong and penetrating even when the husk is intact. Some people regard the durian as fragrant; others find the aroma overpowering and revolting. The smell evokes reactions from deep appreciation to intense disgust, and has been described variously as tert-Butylthiol, almonds, rotten onions, turpentine and gym socks. The odour has led to the fruit's banishment from certain hotels and public transportation in Southeast Asia. (Wikipedia, 2014)

Philippine Durian

The durian, native to Brunei, Indonesia and Malaysia, has been known to the Western world for about 600 years. The 19th-century British naturalist Alfred Russel Wallace famously described its flesh as "a rich custard highly flavoured with almonds". The flesh can be consumed at various stages of ripeness, and it is used to flavour a wide variety of savoury and sweet edibles in Southeast Asian cuisines. The seeds can also be eaten when cooked.

There are 30 recognised Durio species, at least nine of which produce edible fruit. Durio zibethinus is the only species available in the international market: other species are sold in their local regions. There are hundreds of durian cultivars; many consumers express preferences for specific cultivars, which fetch higher prices in the market.

Mount Apo. Is a large solfataric, potentially-active stratovolcano in the island of Mindanao, Philippines. With an altitude of 2,954 metres (9,692 ft), it is the highest mountain in the country and is located between Davao City and Davao del Sur province in Region XI and Cotabato province in Region XII. The peak overlooks Davao City 40 kilometres (25 mi) to the northeast, Digos City 25 kilometres (16 mi) to the southeast, and Kidapawan City 20 kilometres (12 mi) to the west.

Apo, which means "ancestor", is flat-topped mountain with three peaks and is capped by a 500-metre-wide (1,600 ft) volcanic crater containing a small crater lake. The date of its most recent eruption is unknown, and none are verified in historical times.

The volcano is one of the most popular climbing destinations in the Philippines with the summit, on the average, takes two days to reach. The first recorded climb was on October 10, 1880, by a party led by Joaquin Rajal, then Spanish governor of Davao (Wikipedia, 2014).


Mount Apo Natural Park. On May 9, 1936, Mount Apo was declared a national park with Proclamation no. 59 by President Manuel L. Quezon, followed by Proclamation no. 35 of May 8, 1966 then Proclamation no. 882 of September 24, 1996. On February 3, 2004, the approval of Republic Act no. 9237 established Mount Apo as a protected area under the category of natural park with an area of 54,974.87 hectares (135,845.9 acres); with two peripheral areas of 2,571.73 hectares (6,354.9 acres) and 6,506.40 hectares (16,077.7 acres) as buffer zones, provided for its management and for other purposes.

Although a declared a Natural Park, the current climbing trails are littered with rubbish by irresponsible climbers, opening paths for soil erosion across the already denuded mountain sides. Some mountain and social climbing groups conduct climbs after the Holy Week/Easter, the peak climbing season, to clean the affected areas(Wikipedia, 2014).

UNESCO World Heritage list

The Department of Environment and Natural Resources (DENR) submitted Mount Apo on December 12, 2009 for inclusion in the UNESCO world heritage list. The mountain is considered by DENR as the center of endemism in Mindanao. It has one of the highest land-based biological diversity in terms of flora and fauna per unit area. It has three distinct forest formations, from lowland tropical rainforest, to mid-mountain forests, and finally to high mountain forests.

A portion of the eastern slopes are also within the scope of the UNESCO Hydrology Environment Life and Policy (HELP) Network. The Davao HELP Network is focused on building collaboration among watershed stakeholders.
The mountain is home to over 272 bird species, 111 of which are endemic to the area. It is also home to one of the world's largest eagles, the critically endangered Philippine Eagle, which is the country’s national bird.(Wikipedia, 2014)

Mt. Apo
Mount Apo is an excellent source of geothermal energy. Located in Barangay Ilomavis, Kidapawan City, North Cotabato is the Mindanao Geothermal Production Field with a power output of 106 MW, currently the only power plant of its kind in Mindanao.

The Philippine National Oil Company geothermal plant supplies electricity to Kidapawan and its neighboring provinces, its completion boosted the city's economy.

Six indigenous peoples - Manobos, Bagobo, Ubos, Atas, K’Iagans and the Tagacaolo consider Mt. Apo as their ancestral domain and their home. These tribes have lived since time immemorial, around the mountain that they also consider as sacred ground, their place of worship and burial ground of Apo Sandawa, their great forefather. A number of genealogies of known Lumad leaders in South Central Mindanao trace their roots to Mt. Apo. For the Lumads, the term Apo was coined from the name of their great grandparent Apo Sandawa. Mt. Apo is the source of their continual supply of food and medicine, their spiritual and cultural way of life. (Wikipedia, 2014)

Euanthe sanderiana is a flower of the orchid family. It is commonly called Waling-waling in the Philippines and is also called Sander's Euanthe, after Henry Frederick Conrad Sander, a noted orchidologist. The orchid is considered to be the "Queen of Philippine flowers" and is worshiped as a diwata by the native Bagobo people.

Heinrich Gustav Reichenbach originally named Euanthe sanderiana as Vanda sanderiana.

It has two forms, pink and white, also referred to as alba. M. Roebelin discovered the original pink variety in the Philippines in 1881 or 1882. Rudolf Schlechter separated Euanthe from Vanda in 1914 due to structural differences in the flowers. For breeding purposes and registration by the Royal Horticultural Society, however, it is still treated as a Vanda.

Waling-waling Flower

Euanthe sanderiana is endemic to Mindanao in the provinces of Davao, Cotabato, and Zamboanga where it is found on the trunks of dipterocarp trees at elevations below 500 meters. Over-collected, the plant is considered rare in nature. It is often used in hybridization.

Studies have shown that when raised at high altitude, the plant bears flowers early.
In 2004, there had been a motion in the House of Representatives of the Philippines to declare the "Waling-waling" as the country's national flower, replacing the Sampaguita.
In 2013, a bill was passed by the Philippine Senate declaring the Waling-waling as a national flower alongside the Sampaguita. (Wikipedia, 2014)

Mangosteen
The purple mangosteen (Garcinia mangostana), the Queen of Philippine Fruits, colloquially known simply as mangosteen, is a tropical evergreen tree believed to have originated in the Sunda Islands and the Moluccas of Indonesia. It grows mainly in Southeast Asia, and also in tropical South American countries such as Colombia, in the state of Kerala in India and in Puerto Rico, where the tree has been introduced. The tree grows from 6 to 25 m (19.7 to 82.0 ft) tall. The fruit of the mangosteen is sweet and tangy, juicy, somewhat fibrous, with fluid-filled vesicles (like the flesh of citrus fruits), with an inedible, deep reddish-purple colored rind (exocarp) when ripe. In each fruit, the fragrant edible flesh that surrounds each seed is botanically endocarp, i.e., the inner layer of the ovary.Seeds are almond-shaped and sized.

The purple mangosteen belongs to the same genus as the other, less widely known, mangosteens, such as the button mangosteen (G. prainiana) or the charichuelo (G. madruno).

A description of mangosteen was included in the Species Plantarum by Linnaeus in 1753 (Wikipedia, 2014).
