Clennon Valley
The Yellow-browed Warbler was still present this morning and now 3 eastern/Siberian 'tristis(?)' type Chiffchaffs. My question mark is due to the odd almost collybita/abietinus calls 2 of the very pale and washed out (not the normal buffy brown of tristis) chiffchaffs were giving - see video clip - didn't manage to film the bird unfortunately in this clip:

These calls were identical to the pale eastern chiffchaff at Broadsands see posting and video clip for 22 Nov https://www.devonbirds.org/news/bird_news/devon_bird_news?blogMonth=11&blogYear=2013&blogEntry=4156 .
Here are some pictures of at least one of the two pale washed out eastern chiffchaffs, they both responded well to a recording of tristis song with wing quivering suggesting they are tristis or know tristis song very well! None responded to collybita song recordings. Another much warmer browner bird - a classic tristis also present occasionally gave the standard flat tristis 'iip' call.
