- Oddly, while the other two Ice Hunter tribes are extinct animals in real life, vultures aren't; currently, this has not been explained.
- However, these vultures are more likely the extinct bird, Teratornis.
- They are the flying units of the Ice Hunters, although seem to have lost some flight capability as a result of their sedentary lifestyle and zombified, frozen state.
- Despite having gray wings in the sets, they're instead depicted with black wings in the TV series.
