Continuing the good run of white-winged gulls in North Wales, this beast was patrolling the tide-line at Harlech Beach this morning. One of only five gulls present here first thing. It is a different individual to the one that was present on the Glaslyn nearby a couple of weeks back. It is probably a 1st Winter bird although the eye is pale. Any comments would be appreciated. A distinctive gap in the left wing should help identify it if it turns up elswhere in North Wales.
