Vagrant Emperors at Donna Nook

it took about 90 minutes before we found one of Chris's Vagrant Emperors but it landed in the open on the beach, first images, presumably a poorly marked male then we had at least 6 individuals and possibly up to 10 in the next 3 hours over 3kms of dune -- surely if we can find that many in such a small area they must be being overlooked elsewhere on the east coast -- second set of images a female taken after a torrential downpour
