It seems that Avocets are feeding all day long but I have rarely captured what they are eating. However this particular day I was able to capture what appears to be some kind of bug in it's beak. Camera settings were, continuous focus and shutter, 1/1600 sec., f/8, and 700mm focal length. Equipment included Nikon D750, Nikkor 200-500mm f/5.6 lens, TC-14E III teleconverter, Induro Stealth CLT403 tripod, Wimberly WH-200 gimbal head.
