[QUOTE="RecoveringScot, post: 3572077, member: 17473"] Since there has been some comment on Twitter about the paleness of the claws (which in LK according to Corso (2001) are not always 'white' but typically pale greyish with a slight yellowish tinge, and occasionally darker) I include here a blowup of the relevant area. The claws appear to fit Corso's description, and the blackish shadowing appears to be either a photo artefact affecting the central claws, or an effect of the light. The outermost claws on either side are clearly medium greyish, and not black. The toes themselves also appear a richer orangey yellow (a point mentioned by the Andalucia Bird Society in a comparison page, though they say 'ochreous' which to me would mean with a slight greeny tinge) than Common Kestrel, in which they are typically pale clear yellow, like the cere. Photo used with permission. [/QUOTE]
