This defenitely is a bearded vulture: 1:24 But those birds at 0:28 look very different. They don't even have the beard. Are you sure those are bearded vultures?
Absolutely. They wonderful adaptation of bearded vultures is that their diet is comprised of about 90% bone. Therefore, they are the clean up crew the comes in after the clean up crew. Other vulture species eat the soft tissue leaving the bones, and the bearded vultures come in and eat the skeleton leaving virtually nothing left needing to decompose. If a phone is too large for them to swallow, they have often developed a tactic of taking a bone to a very specific spot and dropping it from Heights that allow the bone to shatter into shards that are easily swallowed for them, and which expose the marrow that give them their immediate protein.
