These berries are plentiful on four ornamental rowan trees outside the former Kwik Save store Brynmawr at the moment. This was the venue for a healthy party of waxwing the last time they visited in numbers a few years back. But it seems the current invasion has yet to filter this far south, but we live in hope.
Another site worthy of a check is Tesco car park Pontypool where a similar range of berry bearing trees exist - some nice whitebeams. Although beware, using a pair of bins in a public place anywhere in the valleys is likely to result in disapproving glances or even possible arrest. You can fell some nice woodland during bird breeding season, put a terrier down a badger sett, discharge a firearm in a public place in full Rambo attire or drive your 4x4 repeatedly through an upland bog but demonstrate any affinity to the natural world and you're in trouble. The only way of avoiding a spell in the slammer is to plead insanity by claiming you're a birder/naturalist/ecologist.
