Philippine or Crested?

This handsome dude seems to be a regular visitor to my garden.

At first I thought it was a Crested Serpent Eagle but further research suggests it might be a close relative, the Philippine Serpent Eagle, if only because it's in the Philippines.

This raises two questions: is my garden overrun with 'serpents' and has it been responsible for the cats going missing?

Photos were captured on my Panasonic Lumix FZ18, which is a super-zoom camera bought for me by my sister around 5 or probably 6 years ago.  It's a hugely versatile camera and one that produces photos of amazing quality for what it is.
