In reply to Gaia:
> I thought there is a bird ban on routes when the nests are being used. Obviously I’m not familiar with the route and situation, could someone please clarify? Are there no nests on or near the route? Happy to be corrected but the footage doesn’t look good from a non-climbing perspective.
I think there's been a major leap forward with regards to this in recent years, with any route that has a house martin nesting - or nest building on it - being given a wide berth.
This has been pretty well enforced amongst the climbing community, with the following thread being a particularly good example: https://www.ukclimbing.com/forums/crag_access/nesting_birds_on_raindogs_-_s...
I know you've referenced it within your other post, but I thought I'd copy/paste the line from the RAD just as a reminder as to exactly what it says:
"House martins also frequently nest between May-September, often on the popular hard sport routes (frequently affecting Raindogs, Seventh Aardvark, Bat Route and others). Please avoid any routes with nests on or near to avoid damaging the nests, until the young have fledged. It will be obvious which nests are being used due to parents flying in and out. Whilst routes can be climbed once the young have fledged, they can return to the nest site to roost, so be careful not to damage the nests."
In short: if there's a house martin nesting - or nest building - DO NOT climb on the route.
