Sedge Warbler West Norfolk (riverbank) by Adam Swaine Via Flickr: My focus on the sedge warbler is for two reasons. One is simply as it’s a new arrival from sub-Saharan Africa, a reminder of the miracle of migration. The second links, I think, with keen birdwatchers’ constant search for the new or different. Yes, they’re back – like seeing an old friend after many months of absence. I haven’t heard a sedge warbler for ages..Walking along the Nar Riverbank so tranquil and beautiful to hear and see in spring
