From NC State Parks:
The seasonal wildlife closure of Moore's Wall's North End is now in effect. The closure will run through 08/31/2019, but may open earlier depending on Peregrine activity. Climbing, bouldering, and hiking by park visitors beyond the North End trail point will be prohibited during the closure.
Moore's Peregrine Update (4/11/2019)- The state wildlife biologist was out there recently and there is at least one bird moving around the cliff, hanging around Sentinel buttress in particular. She has not yet been able to find signs of a nest.
