||30 cm. Medium-sized, short-tailed, ground-dwelling pigeon. Large blood-red central patch to otherwise white throat and breast. Iridescent bronzy-green crown, nape, upper mantle and breast-sides (forming an incomplete breast-band). Dark chestnut rest of upperparts with broad greyish bands across wing-coverts. Deep buff belly becoming creamy-white on vent. Subspecies show slight variation in breast pattern. Voice Thought to be a repeated, cooing woo-oo. Hints Feeds on forest floor. Shy, tends to run from danger, typically only flying short distances when flushed.

Forest clearance within this species's range must have led to a rapid reduction of its small, fragmented population; a trend which is set to continue. For these reasons it is classified as Vulnerable.

|Range Description:||Gallicolomba crinigera is endemic to the Philippines, where it is known from Samar, Leyte, Bohol, Dinagat, Mindanao and Basilan (Collar et al. 1999). There are records from c.35 localities, but since 1980 it has only been recorded from Rajah Sikatuna National Park on Bohol, Bislig on Mindanao and during recent surveys on Mount Hamiguitan and Mount Hilong-hilong in eastern Mindanao (J. Ibanez in litt. 2007). It always appears to have been rare throughout its range, although its aptitude for self-concealment may mean that it is under-recorded. Nevertheless, a substantial population decline is likely to have occurred. |

The near-total loss of lowland forest throughout its range has caused its decline. In the late 1980s, 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, with most lowland forest leased to logging concessions and mining applications. Dinagat has lost practically all lowland forest as a result of illegal logging and, particularly, chromite and nickel surface-mining. Bohol is thought to retain only 4% forest cover, with tree-cutting, agricultural expansion and soil erosion all acting as threats to Rajah Sikatuna National Park. Forest at Bislig on Mindanao is being cleared under concession and re-planted with exotic trees for paper production. Elsewhere in eastern Mindanao where the largest old growth dipterocarp forest remain, illegal logging and mining persist at varying levels of intensity. In 2006, DENR-CARAGA Region confiscated 41,232 pieces or 12,998.27 cubic metres of illegally cut logs, amounting to around Php 18 million. Eliminating illegal logging remains difficult, with very limited capacity and logistics allotted by the government for monitoring and law enforcement. There are 51 mineral production sharing agreements (MPSA) at various levels of exploration and extraction approved since 1990 in eastern Mindanao alone. In the Tumadgo Peak IBA, almost 70% of unprotected dipterocarp and cloud forest is under MPSAs. Only 22% of the whole IBA, mostly high-elevation forest, is protected as wildlife sanctuary. Trapping for food and trade is a problem for all terrestrial birds in the Philippines.
