Rufous morph Cuckoo

Clive Bowley came across this super rufous morph (sometimes called ‘hepatic’) female Cuckoo near the feeding station at Summer Leys today.

One was also seen in the vicinity about two weeks ago. I’ve heard it said about 15% of female Cuckoos are rufous but I have no references on this and the proportion may well vary with geographical location. Rufous morph juveniles are much commoner, of course.
