[QUOTE="BSK, post: 5509608, member: 17"] I asked, because we had a bumper acorn crop last year, and I observed/measured some really odd behavior. As I've mentioned before, lots of good research indicating that in a hardwood environment rubbing and scraping activity is driven by how much excess energy bucks have, and that excess energy is provided by big acorn crops. The result being bucks make many more rubs and scrapes in a good acorn year than in a bad one. I've only been running my video surveillance of scrapes project since 2020, and that year was a poor acorn year. So I expected 2021, being a bumper acorn year, to produce more scrape visits. And that's what I saw. But I wasn't expecting the odd timing of those visits. Below is a graph if the number of buck visits to scrapes per day for the two years. Normally, scraping peaks the first week of November for a mid-November peak of breeding. However, in 2021 - the bumper acorn year - scraping actually peaked in late October. In fact, for the first time ever, we had more bucks photographed on the property in October than in November. Looking at buck-doe chases caught on camera, it appears peak breeding occurred on the exact same dates in 2020 and 2021, but the pre-rut sign-making was far more advanced early in the year in the good acorn year. The vertical dashed line on the graph indicated November 1. In 2020, peak of scraping was at the classic time - first week of November. But in 2021 scraping was crazy the last half of October and then fell off into November. [/QUOTE]
