Uploaded on May 9, 2011 I clicked through these scaup looking for a Lesser but all I've seen are Greaters. Greaters because of head shape looking especially for the forehead "lump" of the Greater and lack of peak at back of the head of Lessers. Its obvious that I need a faster camera. I'm using a Panasonic HDC-TM55K Hi-Def Camcorder that shoots at 30 fps with 24x optical zoom. Auto exposure burns out the white in bright light. |
