Peregrines are nesting at the base of Uncle Charlie's Left Nostril, about 12m off the deck, with a couple of tiny chicks in residence. Definitely need to stay off Pearls Before Swine (20), Purler (22), Uncle Charlie's Left Nostril (23) and Bridge (24) for a few months.
The Purler rap station is only 5-6m above and slightly to the side of the nest, so best to also stay off Ciela (28) and Punks in the Gunks (25).
The nest is impossible to see from the ground so it will be hard to know when they've finally left.
