Garden Warbler - Clough Wood

I went looking for Garden Warbler this morning and Clough Wood is one of the best areas for them. They like the mixed scrubby areas and there were at least three males singing. 
The photo was taken at  06:30 this morning with an overcast sky at ISO 5000 using the Canon 5D III. Although the photo is a little grainy I wouldn't have been able to get any sort of shot with the 7D in these conditions.
Saw and heard my first Cuckoo of the year this morning, flying along Harland Edge.
