I've never studied birds of the Himalayas, but a quick glance at that bird makes me think it was some kind of Vulture or Condor. The beak was shaped wrong to be an Eagle. It also had a neck frill that is seen on some species of Vultures.
The pilot sure was mad at that bird! Non-stop swearing at him!
He bleeped out most of it, but I know enough Russian to understand what it was he was saying at that bird, and it was NOT pretty!
At least he untangled him and let him go unharmed. I was thinking he was pissed enough at the bird to kill him.
