Snow Geese – Bosque del Apache National Wildlife Refuge, New Mexico: Bosque is world renowned for its abundance of over wintering Snow Geese and Sandhill Cranes. More than 35,000 Snow Geese invade the refuge by early October and remain until March when they begin their journey back north. These two geese were flying to one of the many water impoundments where they will join other members of the flock to roost overnight. To make this image I used a 300mm lens mounted on a handmade gunstock. An electronic cable release mounted as a trigger operated the camera’s auto focus and shutter release. An auto focus lens and dynamic focus was essential to keep the birds in focus as I panned with them during their fly-by. A rapid 8 frames per-second provide a frame with the wings in just the right position.
