Noisy little thing...

Took this shot through the window right next to my desk at work…
This noisy thing (I think it's called a bobcat in English?) has been buzzing around just outside all day… I almost can't wait until the workday ends today…. Sigh…

Gear used: Olympus OM-D E-M5 + M42 to micro 4/3 Adapter + Panagor PMC f2.8/28mm.
