Not a close up, but a behavior and environment shot of black grouse lekking on a frozen bog near Oulu, Finland, April this year. The fully engorged wattles really stand out in the warm sun at dawn.
From a hide on the bog, gimbal mounted in the hide.
Canon 1DXII and 400/2.8II.
f4, 1/1600, ISO 1000. Minor adjustments in Lightroom.
