In reply to Chris_Mellor:
Hasnt the bird ban been extended the last number of years beyond the start of August date anyway? Surely this would just be fixing it a little more permanently in peoples minds - given the nesting trends already experienced.
Personally, climbing past nesting (or fledging) birds is not enjoyable for many reasons, though inconvenient to the better weather conditions, I'd support the conservation considerations over my climbing interests.
Climbers must be a steady % of visitors and therefore income, but my bet is they are not as significant as other groups of visitors. Climbers are seasonal, historically frugal individuals, use the lower cost accommodation and happy to cook their own food. We are not all this stereotype I know. On a per capita basis I suspect climbers are low yield individuals.
The climbing on, and Lundy itself both hold a special place in my heart. What ever the restrictions, it is definitly worth making the effort to visit.
