Deer Data Graphs

Since about 1999, I have been building and using home-made (aka home-brew) TrailCameras. In 2001, I started keeping the pictures in digital format. Then last year, I started trying to organize the data into some meaningful format.

I found some freeware on the web that stores digital pictures and information, and modified it to incorporate data relevant to deer observation. For each photo, I track information like :

  • Number of deer in picture
  • Number of does
  • Number of fawns
  • Number of bucks
  • Camera location
  • Identification number of buck in picture
  • Option to “Omit” certain pictures from graphs & reporting
  • Date & Time picture was taken
  • Weather/Moon/Sun information


Next I added some more freeware software to generate graphs on the fly. Currently, all I have graphed is deer movement by moon phase, deer movement by time of day, and deer movement by moonphase by the time of day. I am working on how to graph deer movement based on weather changes that occured the day the picture was taken. If you have some statistical analysis experience or trending knowlege, and could suggest some way to create other graphs, email me

Each graph will have a “y” axis that shows the unique number of deer photographed based on the criteria for the “x” axis. Duplicate pictures are omitted. On all graphs, the number of does includes fawns. Deer that cannot be determined as to which sex they are, are classified as Does.

Below are some graphs I have generated from the Trailcam Data:



The graph below show the number of unique deer caught on trailcam during each moonphase listed.  Note the considerable increase in buck movement during the Waning Gibbous phase.


This graph shows the number of unique deer caught on trailcam at hourly intervals. The spike in buck movement at 10:00 a.m. and 6:00 p.m., is fairly consistent on all graphs.
