Nice vid but poor bird.
I wonder how they mounted it.
That cam would look huge to the bird, block out a big chunk of it's vision.
Not to mention how it would change aerodynamics and be right in the way when it tries to catch a fish.
Walk around with something stuck to your nose for a while, see how it effects your vision and perception.
Sorry but seeing people exploiting animals, especially in a way that impacts them physically gets me a bit wound up.
What's even worse is this seems to be an add for Gopro.
PS. Lee this is not aimed at you personally so please don't take it that way.
