Thank you Helene. The green background is the lawn, which is rendered blurred by the f 5.6 at 200mm. I don't have a fancy lens and this was shot with a AF Nikkor 70-200 f4.5-5.6, no VR. I am waiting for my Tamron SP 70-300 f4-5.6 VC, which has received excellent reviews.
By the way, we are having mostly rainy days now, but today morning was quite sunny. You can get some good photo opportunities in winter, I am expecting some good photos from you with lot of snow.
Regards
