I’m stretching my geographical boundaries a little farther than normal to the northwest with this post, but I think the subject deserves it. This is a juvenile Long-billed Dowitcher (Limnodromus scolopaceus), which turned up last week on Rhaslas Pond, just east of Merthyr Tydfil, and has spent the weekend entertaining birders and photographers at point-blank range. Rhaslas is a small artificial reservoir in the middle of bleak moorland, which goes to show that rare (i.e. lost) birds can turn up anywhere.
Long-billed Dowitcher is generally thought of as a North American bird and those occurring at this time of year are most likely to have originated in the Canadian Arctic and been brought across the Atlantic by low pressure weather systems. However, there is also a significant population in Arctic Russia, and some Long-billed Dowitchers occurring here, particularly adult birds in late summer, probably come from that direction. The third possibility is that once here, they stay and migrate up and down the East Atlantic flyway, with godwits or other European shorebirds.
There are much better photographic efforts than mine on the Cardiff Bird Club blog. The photo below shows just how close everyone was able to get (the red arrow points to the bird); indeed, while I was there it kept walking towards the photographers rather than away from them.
Arctic-bred shorebirds have been known on previous occasions in Britain to be just as tame: there was a Buff-breasted Sandpiper (Calidris subruficollis) in Somerset a few years back which allowed an equally close approach, for example. Most famous of all is an Upland Sandpiper (Bartramia longicauda) which occurred on the Isles of Scilly in the 1980s which was so tame it took a worm out of a birdwatcher’s mouth. These birds are invariably juveniles on their first southbound migration and the theory is that because they’ve never seen people before, they don’t associate us with danger: bad news for the individual bird, but great news for birdwatchers.
