Look at any OS map of Gwent and Ponthir Reservoir sticks out like a sore thumb. Why then has it taken birders so long to find it? Its not even listed in the Birds of Gwent as a birding location. Ok itsn't on the scale of the Newport Wetlands or Llandegfedd Reservoir so its capacity to support a rarity will be limited but having visited the site regularly over the past year it can be very interesting for commoner birds.
A lunchtime drop in session yesterday produced 65 tufted duck, 2 cormorant, and singles of kingfisher and little grebe. Late invertebrates included 8 small copper, 2 small tortoiseshell, 2 peacock and 2 common darter.
