That upset some people.
1. You're watching eagles do what eagles have evolved to do, just normal life.
2. Look to your own nature: Why are you peeping on the private life of animals? If anything's disgusting, you're disgusting for peeping. Turn your squeamish outcry against yourself.
3. It's poetic justice. Cats kill birds. Those who let their pussies run wild should remember that the nonnative species they set loose is ravaging the birds who are trying to get along in what is the ecosystem they earned through long years of evolution. Your feline pets are killing 3.7 billion birds annually. The turnabout seen in the webcam is small recompense for the damage done.
