A massive crop. I was actually watching a couple of Goldfinches stealing rapeseed far out in this field, but they kept ducking behind ever new straws, the sneaky buggers. Then in one corner of the frame, I saw an anonymous-looking brown bird, managed more or less to get it in focus, and got a couple of snaps. Turned out to be my first Linnet (thanks to ID forum for ID help). Luckily, I got far better shots of another one a few days later.
