"Eastern" Lesser Whitethroat

Shortly after discovering yet another Yellow-browed Warbler yesterday at Avalanche Road, I was also lucky enough to find an "Eastern" Lesser Whitethroat, though if I'm honest my knowledge is very limited when it comes to the curruca subspecies, although a portrait of the bird was posted on the the PBO website, i've uploaded here a larger selection of images, showing a bit more detail. Unfortunately the bird was never heard to call, however, if it is still present today we will persevere with recording equipment.
