Lib........yes I understand.........I think it is the gulls and crows which are pretty awful to watch. The Hawks tend to hold and squeeze and, in my experience, the prey is dead before they begin to pluck and dismember.
As to the larger birds living longer and learning new tricks.......in the long term that's how species evolve isn't it ?
I suppose that is the way we got where we are today ........disgusting habits and all
Last year, we had to watch a very new Collared dove youngster...........in fact just had it's first feed from parent (or first that we were able to see anyway.)..........a crow came and attacked it in the nest but flew off when I went out in the garden. The youngster, obviously dead, was left draped over the nest. Our neighbours were horrified..........wanted me to climb up the tree and dispose of the little dove. Pointless to do that and I explained the crow would be back to collect it's meal.....sure enough, within the hour, crow came and retrieved it's booty. It's sad to watch but nature is nature and little you can do to alter it.
Do you remember that observation......"If you want to see the most dangerous animal on earth, just look in the mirror" ? Awful but true unfortunately.
Sorry....wasn't meaning to rant
