The Mindanao bleeding-heart (Gallicolumba crinigera ), also known as Bartlett's bleeding heart dove, Barlett's bleeding heart pigeon and the hair-breasted bleeding heart, is a species of bird in the pigeon family. It is endemic to the Philippines on the islands of Mindanao, Basilan, Samar, Leyte and Bohol. It is so named because of a red blotch on its breast. The generic name derives from a fusion of the Latin gallus ("chicken") and columba ("pigeon").

Biogeographical realms

The Mindanao bleeding-heart exists (or used to exist) on the Philippine Islands of Samar, Leyte, Basilan, Mindanao, Bohol, and Dinagat. It is one of the three bleeding-heart doves that are native to their own particular island or islands of the Philippines. It naturally occurs in both primary and secondary tropical lowland rainforests up to an elevation of 750 m.

Biome

Habits and Lifestyle

It is a shy bird which typically runs from danger, spending most of its time on the forest floor, and only flying short distances if flushed. It only perches in trees if frightened or when nesting or roosting. The call is a repeated woo-oo similar to that of most doves and pigeons. It is a rare sight because of its cryptic behaviour.

Seasonal behavior

Diet and Nutrition

The birds feed on the forest floor, foraging for berries, seeds, worms and insects. In captivity they are typically fed grains, greens and parakeet seed.

Mating Habits

Courtship is characterized by slowly raising and lowering the wings at regular intervals of a few seconds. The female lays a single creamy white egg, which it will incubate for 15–18 days (depending on the weather) and the young are capable of flight within 15–16 days of hatching. The breeding period is thought to take place during the rainy season (March through June).

Population

Population number

The main threats to the Mindanao bleeding-heart are deforestation and overhunting for food and for the pet trade. The status of the species is not sufficiently known for a definite assessment. Initially listed as being of least concern in 1988, it was subsequently uplisted to vulnerable in 1994, and further to endangered in 2000. With its exact rate of decline still unresolved, it was downlisted to vulnerable in the 2007 IUCN Red List with the population estimated at 1,000 to 2,499 mature individuals remaining.

This species' main threat is habitat loss with wholesale clearance of forest habitats as a result of logging, agricultural conversion and mining activities occurring within the range. Forest cover was estimated at just 29% on Mindanao, and as little as 433 km2 of old-growth dipterocarp forest remained on Samar and Leyte. These figures are continuing to decline thanks to continued deforestation.

Conservation actions proposed include to survey in remaining tracts of suitable habitat and areas with historical records, particularly on Samar and Leyte. Continue to advocate the effective protection of key sites and potential habitat. Propose remaining forests found to support the species for establishment as protected areas. Promote more effective enforcement of laws relating to hunting and trapping.
