Out of a total of 1,594 bird species existing in Indonesia, 112 are on the brink of extinction and included in the Union for Conservation of Nature (IUCN) Red List of Threatened Species, the Antara News Agency reported on Tuesday.

"Indonesia is a country hosting a very diverse bird population. Of the world's 10,000 bird species, 1,594 are to be found in Indonesia, making it the world's fifth richest country in terms of fowl possession," Ria Saryanthi, conservation program manager of BirdLife Indonesia said in a press statement.

She said that of Indonesia's 112 endangered bird species, 18 were in critical condition, 31 endangered, and 73 others prone.

Most of the threatened bird species are being threatened by hunting, illegal trade and pressures on their habitat due to illegal logging and forest area conversions.

"Human activities which have converted forests into agricultural areas, plantations and infrastructure development for industry, have caused the bird habitats to shrink," she said.

Wood pigeon (Columba sp.), uncal (Macropygia sp.), delimukan ( Chalcopaps sp. and Gallicolumba sp.), pergam (Ducula sp.), and walik (Ptilinopus sp.) are pigeon families which are highly depending on their forest habitat.

"It is no surprise that of the total of 112 threatened bird species, 12 are from the Collumbidae families," he said.
