Another Chiffchaff ........

Normally I try to avoid reeds and vegetation in front of birds as they generally detract from the subject. 

However in this case I think the colour and angle of the reeds compliment the image and contribute to the feel of the overall setting and background habitat  of the photograph.

Overall focus of the bird is consistent from its beak to the tip of its tail and the black legs in the fore are also very well defined.

For me, a very pleasing result, I don't get it right very often.
