<\/p>\nJust an odd little idiosyncrasy about photographing birds.<\/p>\n
As a general rule there’s an inverse correlation between bird size and wing stroke speed – the smaller the bird the\u00a0faster the speed of the wing beats. Camera burst rates vary but I’ve found that the wing speed of many moderately sized birds (some corvids and raptors for example) matches that of the burst rate of my two Canon 7D’s (8 frames per sec). This phenomenon can produce multiple sequential images with almost exact poses in flight and that can be either good or bad.<\/p>\n

The flight postures aren’t identical but they’re pretty darned close.\u00a0There are times when I’ll get 4-5 sequential shots with almost the same flight pose. That\u00a0can be good news if\u00a0I like the wing position but if the wings are horizontal I’ll often delete the entire batch.<\/p>\n My new Canon 7D Mark II has a burst rate (with a fast memory card) of 10 frames per second so I’m anticipating getting the same effect with somewhat smaller birds, say perhaps the size of mockingbirds.<\/p>\n We’ll see if that’s what happens.<\/p>\n Ron<\/p>\n Note:\u00a0 In the last few weeks I’ve received many inquiries asking if Farmington Bay will be killing carp this year (they didn’t do it last year because of health issues with Bald Eagles).\u00a0 John Neill, Avian Biologist for the Great Salt Lake Ecosystem Program\u00a0reported on Ubird this morning that it will occur.\u00a0 Here’s the direct quote:<\/em><\/strong><\/p>\n “Yes there will be a rotenone treatment done prior to Bald Eagle Day, which is Saturday, February 14.”<\/em><\/strong><\/p>\n I suspect, as in previous years, that it will be done significantly before the 14th but I don’t know\u00a0that for sure.<\/strong><\/p>\n![\"black-billed](\"https:\/\/featheredphotography.com\/blog\/wp-content\/uploads\/2015\/02\/black-billed-magpie-6672-ron-dudley.jpg\")
