Hairy Hodgson's Frogmouth

Anyone have any idea if the "hairy" head have any other purpose other than help in camouflage? I was wondering if the hairy feather on the head is use as a mosquito net to prevent insect from getting near their eyes? Or act as sensor to pin point the location of the insect and help them in hunting? 

Frogmouth are known to good in camouflaging. When they stay motionless, is hard to spot them if you don't know their exact location. This made them vulnerable and give the insect an opportunity to attack their eyes.

An insect managed to bypass the hairy head and landed on the left eye of the frogmouth. What do you think?
