Thanks to Mark Breaks, Jean Roberts, Pete Woodruff, Mike Watson, Chris Batty and especially Gav Thomas for going through the Meds and coming up with an excellent series of colour ring sightings, including three ringed on the same day at a German colony. Special thanks to Ian Walker for finding the Bonaparte's Gull and catalysing visits from birders as the three main local observers were all unfortunately incapacitated for most of this month. Hope you recover from your op soon, Pete (Cook).
