I recently spent five days at the Aeron View Campsite in Tregaron Wales (nr Aberystwyth) - Link here: http://www.aeronviewcamping.co.uk/
They don't advertise it, but they have A LOT of Red Kites in the area - something like 100 of them, and apparently it's the largest flock in Europe.
The guy that runs the campsite feeds them offal from the local butchers at around 16.00 every day... this is just a very brief video of feeding time. Note the hard hat, it's needed!
Even without the daily bird show, it's a great camp site. The excellent reviews online are justified.
Although the current owners are moving on after this season, so the vibe might be a little different in future years!
