Arrived up Dowlais at 1pm to hunt for the white wingers when I got a call from Mike who was watching the Glauc' on Peacocks roof. I joined him by the slaughterhouse to get excellent views of the bird before it crossed over to the South facing part of the roof. Making my way round to ASDA's car park as I statrted to scan through the gull, most took off for the tip. I hung around to about 3:20pm but didn't get the Glauc again and there was no sign of the Iceland.
