One of the big birding events of this winter has been the record influx of Iceland Gulls, and anyone with an interest in gull-watching will hopefully have made the most of the opportunity to study this scarce Arctic species. The closely related Kumlien's Gull has been caught up in the influx too, and there have also been reasonable numbers of Glaucous Gulls around Britain and Ireland. There's therefore no better time to get to grips with these large, and largely white-winged, species before they head north-west for the summer.
For this reason Peter Adriaens looks in more detail at the specifics of Iceland v Kumlien's Gull in the April issue, and we'll be uploading more photo resources on the Birdwatch website to supplement this in-depth photo guide. But especially for those with less experience of gull ID, this British Trust for Ornithology video on YouTube offers additional advice on the identification of Iceland and Glaucous Gulls:
