Heh heh.
This was a fluke shot. There was a bunch of sparrows milling about, so I just took some shots of them with my 70-200mm.
The sparrows are not sharp because they were moving quite fast, and the depth of field was very shallow.
I got a nice surprise when I viewed the pictures on the screen. Had almost deleted this one on the spot.
"Sparrow aerobics" was the first caption that came to mind. On hindsight I should have captioned it "Sparrow ballet". Can you say "Sparrow Lake?"
Technical: f2.8, 1/500 sec, ISO 400, at 200 mm (from EXIF data).
