Thank you to Ian and Lorraine Winney for forwarding me these two photos of an albino jackdaw. I have seen this particular bird on several occasions feeding on the ploughed field south of Hadham Ford but have never been able to manage a photo of it. It appears to have moved a short way north now, probably feeding with the flocks that move up and down the valley. I'd be interested to hear of any other reports of this as it will be an easy bird to track its movements. Very odd, as most birds with this condition normally fall easy prey due to their inability to be camouflaged. Probably just a tad too large for a sparrowhawk. However, this appears to be doing well as one of the photos depicts it gathering nesting material.
Interestingly enough, there is a bird identical to this (apart from the fact it's stuffed!) in the Natural History museum.
