Lockdown day 29 - Lesser Whitethroat

Much the rarer of the two whitethroats I suspect that the Lesser Whitethroat is a rare breeding bird in the Darley Dale area. I saw my first of the year today and in the same area, between Wensley and Winster, that I saw one several times last year. 
This bird, a male as it was singing occasionally, was feeding in a Hawthorn hedge, not sure what the caterpillar is in the photo.
