If they breed again next year I suggest you don't climb up to the nest. Apart from being against the law, assuming you don't have a permit to do it, the activity is likely to attract the attention of the local predators and scavengers. The parents for example might have been displaying while you were near the nest and that would have been like a beacon to a buzzard. Or they might just have wondered what the ladder was for and why someone was climbing up into the tree. Buzzards are not the brightest of birds but they aren't daft when it comes to finding food.
