Abstract: Information on threatened endemic birds of Cebu, generated over three years of monitoring (2001‐2004), revealed a number of supposedly extinct bird taxa surviving in small, degraded forest patches. Methods used in our surveys included mist-netting, line transects, point counts and interviewing key local persons. Four threatened Philippine endemic birds were observed in at least two sites on Cebu Island. Seven of the twelve endemic subspecies from Cebu were confirmed extant. Twenty forest birds presumed extinct in Cebu were rediscovered. In addition, we mist-netted the first Chinese Goshawk for Cebu and one Phylloscopus warbler showing characteristics of Yellow-browed Warbler, a species not previously known from the Philippines. On the other hand, we did not find the Cebu endemic races of White-bellied Woodpecker Dryocopus javensis cebuensis, Blackish Cuckooshrike Coracina coerulescens altera, Bar-bellied Cuckooshrike Coracina striata cebuensis and Philippine Oriole Oriolus steeri assimilis along with 16 other forest bird species that may now be extinct or nearly extinct on Cebu. The surviving populations of threatened and endemic birds of Cebu largely depend on the persistence of small forest patches; hence, the condition of these populations is precarious.

Global patterns and drivers of avian extinctions at the species and subspecies level.
TL;DR: The finding that, when subspecies are considered, the extinction rate has accelerated in recent decades is both novel and alarming.

Vocal divergence and new species in the Philippine Hawk Owl Ninox philippensis complex
Pamela C. Rasmussen,D. N. S. Allen,Nigel Collar,B. Demeulemeester,R. O. Hutchinson,P. G. C. Jakosalem,R. S. Kennedy,F. R. Lambert,L. M. Paguntalan +8 more
TL;DR: It is shown, based on morphology and especially vocalisations, that the Philippine Hawk Owl Ninox philippensis requires treatment as seven allopatric species and at least one additional subspecies and is formally name for science.
An integrative species delimitation approach reveals fine-scale endemism and substantial unrecognized avian diversity in the Philippine Archipelago
Peter A. Hosner,Luke C. Campillo,Michael J. Andersen,Luis A. Sánchez-González,Carl H. Oliveros,Rolly C. Urriza,Robert G. Moyle +6 more
TL;DR: Genetic and phenotypic information support the hypothesis that polytypic bird species in the Philippines tend to be composed of evolutionarily distinct, range-restricted, allopatric replacements rather than widespread and variable “superspecies”.
