Female Chaffinch (Fringilla coelebs)
The shortest day of the year isn't a sensible day to practice birds in flight shots, but then I have never claimed to be sensible. A dull damp over cast shortest day doesn't lend itself to noiseless shots at fast shutter speeds.
I managed this shot using a hint I picked up at one of the talks we heard at the Photography and Video show earlier in the year. It hasn't turned out too badly.
