Pink-bellied imperial pigeon

The pink-bellied imperial pigeon (Ducula poliocephala), also known as the zone-tailed pigeon, is found in the Philippines. It is a large and striking dove reaching sizes of up to 42cm long. The pink-bellied imperial pigeon is mostly dark green, with a pale gray head, an appropriately pink belly, and a brown, black, and gray pattern on its tail. Its eyes and eye ceres are red. Its natural habitat is tropical moist lowland forest. It is threatened by habitat loss.[2]

Description and taxonomy

edit
 
An illustration.

Ebird describes this as "A large pigeon of foothill and lower montane forest canopy with a white head, a dark bluish-gray chest and upper back, green wings, a whitish belly with a pink tinge, and rufous under the base of the tail. Note the large red eye-ring. Somewhat similar to Mindoro imperial pigeon, but the pink-bellied has a dark neck and chest. Song is a deep, booming, upslurred “doo-dup! doo-dup!”which can be heard from a distance."[4] It is believed that these birds are strong fliers and are capable of flying inter island.[2]

This species is monotypic.

Ecology and behavior

edit

It is a frugivore. Usually occurs singly or in small groups even with other doves such as Mindoro imperial pigeon, Metallic pigeon, Spotted imperial pigeon and Green imperial pigeon. Its flight is fast and direct, with the regular beats and an occasional sharp flick of the wings that are characteristic of pigeons in general.

Nothing is known about its breeding habits. [5]

Habitat and Conservation Status

edit

Its natural habitat is tropical moist lowland forest and montane forest up to 1,500 m. According to the IUCN Red List and BirdLife International's Red Book, the pink-bellied imperial pigeon is classified as Near-threatened. However, The National List of Threatened Terrestrial Fauna of the Philippines has classified it as Critically Endangered.[6]

This is due to the loss of habitat, trapping for the pet trade and hunting for food. Although it occurs quite widely within the Philippines, this species is scarce and probably has a moderately small population, which is suspected to be in moderately rapid decline owing to hunting and the removal of its favoured lowland forest habitat. [7] This bird is extremely rare in Luzon but frequently more commonly observed in Negros Island, Mindoro, Samar and Mindanao. It was believed locally extinct on Cebu but there have been multiple reports in Alcoy since 2003. This species has been bred in captivity by the Talarak Foundation in Negros.

This species is extremely poorly known and more surveys are required to better understand its biology, population and true conservation status.

Under the Philippine law RA9147, it is completely illegal to hunt these birds or to capture and keep them as pets.[8] As it is crically endangered species on the Philippine Red List, any violations have harsher punishments including "imprisonment of four (4) years and one (1) day to six (6) years and/or a fine of Fifty thousand pesos (P50,000.00) to Five hundred thousand pesos (P500,000.00), if inflicted or undertaken against endangered species;"
