The DENR National Capital Region, through its West Field Office (WFO), retrieved two Long-tailed Macaque (Macaca fascicularis philippensis) in Bacood, Sta. Mesa, Manila.

The retrieval was made following a report sent through the social media hotline of DENR National Capital Region. The primates, according to the report, have become aggressive, posing danger to the public. This aggressive behavior, according to studies, may be due to stress as a result of being held in captivity.

Section 27, par. (f) of Republic Act No. 9147 or the Wildlife Resources Conservation and Protection Act of 2001 prohibits the collection, hunting, or possession of wildlife, their by-products, and derivatives without a permit from the DENR and the Bureau of Fisheries and Aquatic Resources (BFAR) of the Department of Agriculture.

The population of long-tailed macaques has declined by as much as 30 percent, according to a study conducted by the International Union for Conservation of Nature (IUCN). The decline, the report added, was mainly due to hunting and habitat destruction.

The long-tailed macaque is now listed under the “vulnerable” category of the IUCN's Red List of Threatened Species.
