It is made from the parent's own downy feathers which is held in place using spider silk, moss and lichens.

[4] Like other species in the genus Batrachostomus, the Philippine frogmouth has elongated bristles around the base of their bill, believed to protect their eyes from prey.

[5] Male calls are a series of low, deep woah, wash, Guam, or g-aw noises, or a short even trill.

[6] The Philippine frogmouth is currently listed as species of least concern by the IUCN as of 2012, though it is believed its population is slowly declining due to habitat destruction.

The reason for this listing is the large range, the rate of decline not reaching the threshold to qualify as a vulnerable species, and while the population size has not been officially quantified, it is believed to exceed the threshold to be considered vulnerable based on the population size criterion.
