The Streak-breasted Bulbul

Ixos siquijorensis

Named after the dark brown streaking on its breast1, the Streak-breasted Bulbul is actually divided into three different populations that look just a bit different from each other, located on four different Philippine islands.

Ixos siquijorensis cinereiceps which has a duller cap on its head and lives on the islands of Tablas and Romblon, Ixos siquijorensis siquijorensis which has a darker cap that contrasts with the rest of its body and lives on the island of Siquijor, and Ixos siquijorensis monticola on the island of Cebu2. This suggests that the Streak-breasted Bulbul may be an old species that was once abundant throughout the islands but has evidently declined in population.

The Streak-breasted Bulbul's 3 populations (Ixos siquijorensis) can only be found on the Philippine islands of Cebu (Ixos siquijorensis monticola), Tablas and Romblon (Ixos siquijorensis cinereiceps), and Siquijor (Ixos siquijorensis siquijorensis).

The Streak-breasted Bulbul is an endangered species2

On the islands of Cebu and Tablas the Streak-breasted Bulbul competes for resources with a far more abundant bird called the Yellow-vented Bulbul, resources that are further reduced by logging. In Siquijor only four forest patches remain totaling less than 8 square kilometers and logging there continue as well2.

How you can help

The following organizations contribute not only to the conservation of this particular species, but to the diverse range of birds found in the Philippines.

The Wild Bird Club of the Philippines

Established in 2003, The Wild Bird Club of the Philippines is the pioneer bird watching club in the nation dedicated to promoting bird watching as a hobby and as a responsible way of enjoying the Philippines' most coveted natural habitats. The volunteer-led club contributes to the conservation of Philippine endangered birds by promoting bird watching as a healthy and recreational practice, encouraging responsible behavior from local communities and tourists alike, as well as environmentally-responsible policies from local governments and officials.

The Haribon Foundation

Started in 1972, Haribon, named after the Philippine Eagle's name in Filipino for "Bird King", gave birth to the Philippine environmental movement. Eventually coupling itself with international conservation organizations such as BirdLife International and the World Wildlife Fund, Haribon has contributed greatly not only to help establish conservation reserves and parks for Philippine birds and other species domestically, but to publications that put the Philippines on the map internationally in regards to its unique but endangered bird populations.

The Philippine Eagle Foundation

Since 1987 the Philippine Eagle Foundation has been focused on saving the Philippine Eagle and consequently saving hundreds of other species that live within its forest realms in the southern Philippine island of Mindanao. With the help of donors and grants, the foundation conducts research, rehabilitation, and captive breeding programs.

Help endangered birds worldwide

BirdLife International is the world's largest partnership of conservation organizations. 117 organizations make up this partnership in over 100 countries across the globe, including the Philippine's own Haribon Foundation. Together, they create bird mascots and flagships to help push for the conservation of endangered birds, consequently conserving the forests they reside and the other wildlife in these areas. By doing so they conserve biodiversity in these areas to improve the quality of people's lives and integrating bird conservation into sustaining people's livelihoods. A symbiotic relationship is then created between people and the environment, as opposed to the "one uses the other" practice that is currently established the world over.
