They are the largest flying birds in the world, with records of 3.5 metres wide with wings open and 1.5 metres high, although we also have stories of larger condors.
In short, their habitat is increasingly threatened by human development, which is why there are fewer and fewer of them and why we have to travel long distances to see them. That is why we include this amenity in long-distance routes so that we don’t have to sit for long periods of time in transport.
