Description
The Philippine hawk-owls are earless. The males and females look much alike. They differ in size and pattern on the bottom side. N. reyi and N. spilonota are the biggest and N. philippensis, N. spilocephala and N. mindorensis the smallest. The pattern on the bottom side of N. reyi, N. p. spilonota and N. mindorensis is checked. The pattern on all the other species are striped.
Species range in size (including the tail) to a length of 21.0 to 26.5 cm and have a wingspan of 16.5 to 20.5 cm.
All are species splits from what was once recognized as a single species, N. philippensis, known together as the Philippine hawk-owl. Two of the owls have been recognized in 2012 as distinct species based on vocal and other differences. They were also previously characterized as subspecies.
