I decided to leave the game camera in place for one month, just to tally up the amount of deer activity it recorded. So being a nerdy biologist I made some graphs of the results, which may or may not be of interest to any of my readers.
Activity on the deer trail at the back of our property was concentrated between the hours of 6 p.m and 7 a.m., with most of the sightings between 9-10 p.m. and 3-6 a.m. Reference sources indicate that northern temperate deer are primarily crepuscular (active at twilight) in the winter and spring, with more activity in the late afternoon in the winter. That does not appear to be the case in my backyard herd.
The activity pattern did not change much over the month of February, although daylength changed from less than 10 hours to more than 11 hours of daylight. It would take more than a month’s worth of data to see differences in the activity pattern. There were roughly equal number of sightings of deer moving north along the trail as south. This is a well-traversed path, judging from the compaction of the trail.
There were 26 sightings of individual deer on 13 dates over the 30 days, with a breakdown of sex and age as follows.
I believe there are four does, two bucks, and at least 3 yearlings in the backyard herd. A higher representation of does to yearling sightings must mean the younger animals avoid this trail for some reason.
That’s all for now. Maybe the pattern will be different next month — or some other animals besides deer might show up on the game camera.
