One of two Chiffchaffs at Marston today is a monochromatic type that probably fits best in that nebulous abietinis/fulvescens pigeon-hole (a couple of -ve tristis features inc. bare-part colouration). I took some images and got one poor sound-recording in windy conditions - will distribute later.
Also 13 Curlew and 2 Little Egrets.
