Planning a visit

Last year I watched with amazement BBC's Springwatch and fell in love with the reserve. I'm planning a visit in June and was wondering if anyone would be so kind to tell me how many days it would take to cover the reserve in detail? I would like to get photos of Pied Flycatcher, Dipper, Buzzards, Peregrine and possibly a Barn Owl. Is there any hot spots in the reserve where I might have a better chance of getting these?
