Yes. The Peregrine was the highlight of being stuck on Sao Nicolau by the local airlines for longer than we were scheduled. I have a recollection of a photo of one since taken on Boa Vista by someone on a one week or two week holiday but I may be mis-remembering that.......
All the best
Isn't this the answer?
When I went, we did the Raso crossing twice and messed around off Tarrafal one evening but if I went back, I'd do what the WP Big Year guys did.
