Mindanao serin
The Mindanao serin (Chrysocorythus mindanensis) is a species of finch in the family Fringillidae. It is found in the Philippines in the areas of Mount Katanglad and Mount Apo. Its natural habitats are subtropical or tropical moist montane forest and subtropical or tropical high-altitude grassland. The Mindanao serin was formerly considered conspecific with the Indonesian serin (Chrysocorythus estherae), together called the mountain serin, but was split as a distinct species by the IOC in 2021. The Mindanao Serin was first described by S. Dillon Ripley and D. S. Rabor from an adult male collected in 1960 by R. B. Gonzales. The original description also includes a color illustration by Robert Verity Clem, and the type is located in the Yale Peabody Museum. References
