Philippine Starlings: Synanthropic Migration Insights
Philippine Starlings: Synanthropic Migration Insights Amiel Gerald A. Roldan™ August 16, 2026 The widespread occurrence of *Aplonis panayensis* (Asian Glossy Starling) in association with poultry facilities across Quezon Province and other regions of the Philippines, together with documented cavity-nesting on utility posts in Mandaluyong, indicates residency coupled with facultative local movements rather than classical long-distance migration. This pattern underscores the species’ pronounced synanthropy and the broader plasticity of avian space-use within the archipelago’s human-modified landscapes. BirdLife International classifies *A. panayensis* as non-migratory (resident) throughout its Southeast Asian range, including the Philippines, where the nominate subspecies *A. p. panayensis* is widely distributed. The species is highly gregarious, forages on fruits, nectar, and invertebrates, and nests in natural cavities as well as anthropogenic structures such as building crevices...
