Wisconsin Turkey

Snapshot Saturdays are a weekly feature on the Wisconsin Department of Natural Resource’s Facebook page. Give them a Like to keep up with recent DNR news and to view the weekly Snapshot Saturdays. 

Restoration of the wild turkey population remains one of the greatest wildlife management success stories in Wisconsin. In fact, turkey are the fourth most common animal captured on Snapshot Wisconsin cameras accounting for 4% of the wildlife photos behind deer, squirrel and raccoon.

Natural Design

The destiny of a Snapshot Wisconsin photograph is to contribute to a one-of-a-kind data set, ultimately supporting management decisions related to Wisconsin’s wildlife. However, the development of this data set is not the only goal of the project. The photos, through their collection and distribution, also serve to pursue the goal of public engagement. As the project has grown, as has our collection of incredible wildlife photos, and the photos have begun to speak for themselves. For me, personally, the fact that we can’t entirely control what the photos will look like (i.e. which animals will present themselves for a photo, and what they will be doing) adds to the appeal.  Trail camera photos show life uninhibited – especially with the increasing quality of the photos as technology improves. Many of our crowd-sourcing volunteers and trail camera hosts can attest that not every trigger captures a moment in time with crisp detail, however. That is the nature of trail cameras. Recently achieving the milestone of over 2,000 cameras on the landscape, Snapshot Wisconsin has learned some simple camera deployment tricks to increase the chances of catching a spectacular photo.

This turkey photo captured in Waupaca County has some diffuse back-lighting, so no details are washed out on the subject.

A trail camera operator who wants to maximize the visual appeal of their photos can benefit from considering some properties of traditional photography. First, let’s talk about light. The camera will read the amount of available light and automatically adjust its settings, but the camera operator does have some control over the direction of light in the photographs.  Some Wisconsin animals have crepuscular activity patterns, meaning they are most active at dawn and dusk, when the sun is low on the horizon. We often recommend positioning cameras to face north so that animals will never be back-lit and overpowered by the bright sun, as they may be if the camera is facing east or west. We recommend north over south because Wisconsin’s relatively high-latitude position in the Northern Hemisphere means that the sun will always be hanging in the southern sky, especially in the wintertime. The best compass bearing for the camera will undoubtedly vary from site-to-site, however. Take the above turkey photo, for example. This photo was taken at 10:42 AM, and the shadows cast by the trees indicate that the sun is behind the subject. This camera is likely facing east. In this case, the forest is dense enough to block out the light directly, and the trail appears to be coming up a slope. The key here is to consider where in the camera’s field of view the light will be coming from.

A Jackson County bobcat entered the camera’s field of view at a distance of around 15 feet.

The next consideration, image sharpness, is a little more difficult to control. There are a lot of factors that can play into how crisp or soft an image will be, including how quickly the animal is moving, where it decides to enter the frame, and when it visits the camera site (sharp nighttime photos are notoriously rare).  For locations along a clearly defined game or maintained trail, a few helpful considerations can be made. Our cameras tend to take the sharpest images when the subject is around 10-15 feet away. Placing the camera at approximately this distance from where animals are expected to cross in front of the camera can increase the chances that the animal will be in focus.

This red fox from Oneida County seems to pose for a portrait. The snow-heavy branches frame the scene nicely, and the fox’s red coat stands out in contrast with the white background.

The final element that I’d like to touch upon is composition. What makes the composition of a photo “good” is difficult to discuss, not only because it’s a matter of opinion, but also because the composition within the frame can change based on the time of year. Not to mention, we can’t always predict where in the frame the animal is going to be captured and in what position! This is tied to one of my sentiments at the beginning of the post – the composition is often special because we can’t control the details. This concept known as “natural design”. It’s familiar to most of us who have a fondness for nature; a glen of naturally-scattered ferns has a special quality that just wouldn’t be the same if they were hand-placed.  Our trail camera hosts often have a relationship with the natural design of their unique camera site, which has resulted in Snapshot staff curating individual collections of our own favorite snaps.  Of course, being aesthetically pleasing does not give a photo any more weight in our data set, but the potential for such photographs is another reason that Snapshot Wisconsin is such a special project.

June #SuperSnap

This month’s #SuperSnap features a mink from Waupaca county, stepping into ice cold water. Mink are amazing swimmers and divers. Even in the winter, you ask? Yes, thanks to insulation from a thick underfur & oily hair, minks maintain their aquatic lifestyle year round, although less so when it’s cold.

Thanks @Tjper for nominating this sequence!
