[QUOTE="BSK, post: 5274069, member: 17"] Below is the photographic history of each older buck in the photo census for 2021 (I have this data for every year for the last 20 years). In the graph, each horizontal line represents an individual older buck. Orange lines are 2 1/2-year-olds, red lines 3 1/2-year-olds and purple lines mature bucks (4 1/2+ year-olds). The diamond markers along the line indicate a date that individual buck was photographed. Notice some older bucks are photographed almost daily, with a few short gaps of not being photographed. But some bucks had [U]long[/U] periods where they were not photographed. And there's a few bucks that were only photographed once and then never again (the solitary diamond indicators). The vertical dark blue lines indicate the period we believe is peak breeding. The pattern of few bucks early in the season then a massive surge in mid to late October is fairly normal. However, the massiveness of the surge in 2021 was unique. Normally this "rut range shift/expansion" only comprises about 1/3 of all bucks picked on camera in a given season. In 2021, this rut range shift made up 72% of all bucks caught on camera (34 of 47). I'm not sure why it was so big this year. I suspect it was because the local farmers didn't cut their corn until very late this year. In most years, corn starts being harvest in early September, which drives the seasonal range-shifting deer up into my hill-country hardwoods in mid-September. In 2021, corn didn't get cut until mid-October, which means the seasonal range-shifters didn't shift to my place until mid-October hence got lumped in with the rut range-shifters. [/QUOTE]
