The frogmouth a group of nocturnal birds related to the nightjars. They are named for their large flattened hooked bills and huge frog-like gape.
The Philippine Frogmouth (Batrachostomus septimusis) is an endemic species found throughout the Philippines. The ones in Mindanao are of the nominate subspecies septimusis.
In May 2014, I had a chance to see this species while on a trip to PICOP, Mindanao. In an inconspicuous part of a dark patch of forest, sat a lone upright figure than was motionless and could pass off as another stick.
The Philippine Frogmouth sitting on at the end of a horizontal branch with 4 side branches projecting out. The mound it sits on is the nest that consist of its own downy feathers which is held in place using spider silk, moss and lichens. An on it presumably sits a single egg.
