Ever since I started using only video for my own personal camera censuses, I've noticed an odd "coincidence" when it comes to does and scrapes. I've noticed that does always interact with the overhanging limb of a scrape. This makes sense because scrapes develop underneath licking branches that are used all year round by all adult deer. But what I've found very interesting is the fixation that develops in does for the ground scrape just before they come into estrus. Generally, about 5 days before estrus kicks off in earnest, I will see does suddenly paying attention to the ground scrape under the overhanging limb. And I mean really paying attention to it, as in sticking their nose in it for minutes on end. This has become such a predictable harbinger of upcoming estrus that I specifically look for it in the videos each November.
