The four heavily cropped images below were taken this evening in Swingates House, (thanks to Roger and Chris Andrew for allowing entry to the grounds). They have been sharpened by 10%. Colours are natural and unaltered.
The bird was found by Martin Elliott on Thursday evening by its' unfamiliar song at Swingates and some images were taken. The images were checked on Friday and its' identity confirmed late on Friday night. Martin Elliott also refound the bird at about 7am on Saturday (today) in the same location and about half an hour later on Land's End car park. The bird was also independently located by Bob Bosisto a little later.
What the authorities will make of this occurrence will no doubt be discussed at length; however from these images below, the condition of the feathers would appear to be good. From the right side, there appears to be no abrasion or damage to feathers. Sadly I have no shots of the left side.
