Another great day on Scilly! Up early again this morning and around the Garrison, not much happening. So, around 08.00 head back to Higgo's project pool on Lower Moors again to see if the waterthrush is around still. I still feel I haven't properly got to grips with the bird's precise structure, shape and markings. Not long after arriving, another old friend and top illustrator, Ren Hathway turned up. We spent over an hour there waiting but no sign of the waterthrush. Amazingly we heard the long-staying Bee-eater fly over us whilst waiting at the pool, and later still Ren suddenly spotted a Wryneck perched up in the nearest adjacent Willow which I barely got onto before it flew across the pool and perched up in an Elm where I managed to scope it and get a quick sketch before it disappeared from view. Later we decided to go and have a look for the Black-and-white Warbler on the other side of Lower Moors. Just as we reached the allotments by the town dump, I suddenly heard the Northern Waterthrush calling at very close range about 8-10 ft up in some Elms - it's never been heard of here before! Despite scanning we just couldn't see it perched, but then suddenly it flew out giving naked eye views only as it attempted to cross the mound of the tip walls, before returning and seeming to perch up in the line of elms between the footpath and the tip. After several anxious minutes of hearing it call a couple of times it went silent. Was it still there? Had it gone? We then decided to head back to the pool, several minutes walk away. While we were approaching the pool, we met another birder who'd just seen it there 5 minutes earlier - it had clearly flown here straight from the tip. We failed to see it again and went back to the old plan of looking for the Black-and-white Warbler. More time passes, and no joy with that. Decided to head toward the airfield when I suddenly heard the Bee-eater calling at 12.58. I franticly scan the sky, and bingo, finally see it this time, such an elegant shape, long-winged, and I can even see the tail streamers.
