OK!! you guys win, I am not 100% sure what this bird will turn out to be, I personally would like it to be a Hume's but I think it will go down as Y.B.W.
Hume's Leaf Warbler which was once Hume's Yellow Browed Warber before it was split into it's own seperate species, Humes leaf warbler. It is very closely related and simiilar to Yellow Browed Warbler and at times inseparable on plumage in the field. They are best told apart by the call and this bird was making calls like Humes and also heard by observers to make Y.B.W. calls. The bird in Question also has plumage that occurs on both birds making the ID a bit of a nightmare, also Hume's are usually duller and this bird can look dull and cold but when in good light This tiny warbler is prone to vagrancy and is a late vagrant to Western Europe and the UK due to the distance it comes approx 4,000 miles from its Mountain Breeding grounds in China and Mongolia. They usually migrate over the Himalayas to winter in India and ajacent regions. They are recorded anually in the UK with about 1-6 on average on a good year so you can see it is a much sought after bird. On the same day and weather conditions 2 other Hume's were claimed in Shetland and South England. Yellow Browed Warbler occurs more often and earlier in the UK, This little vagrant arrives in September - right through to November thus both bird overlaps causing more confusion. It comes from its breeding grounds Ural Mountains and N.E. China about 3-4000 miles, which is a shorter than the 4,000 miles + they would have fly to reach there wintering areas in Southeastern Asia Several hundred can arrive in the UK in autumn but is a prized find on the west coast and South England. With call recording going on You-Tube and Photos being looked at Nation wide it still has split a few Birders to what it is. CAN YOU NOT HELP?? |
