Tell the difference or similarity between the scarce Yellow-browed Warbler / Cekup Kening Kuning or the fairly common Arctic Warbler / Cekup Artik.
Look for tell tale supercilium, tertial tips (back of wings), number, size and state of wing bars and length of tail.The tertials are dark almost black well contrasted by the overall plumage, and well tipped too, forming clear patterns of white, which first caught my eyes. Only thing I'm not sure is its call- similar or different?
Both are migrants to Fraser's Hill. Mountainous forest, Dec 2011, 8:00 am.
