Raccoon in swamp (6/11, Muller Field Station) |
Six days earlier, Sasha Mackenzie and I set out eight Cuddeback Capture cameras (four infrared and four white light flash). We set them in various locations. For example, we attached one to the leg of a bench in the lawn near the channel, baited with a tin of sardines. Another we placed in some ash trees, baited with Squirrel Paste (Havahart product). We even got in the canoes and set five cameras along the channel, hoping for some semi-aquatic mammals. I concocted a bait from the sardine oil and Vaseline. The petroleum jelly acts to hold the oil in place longer than the oil alone. From past experience, we knew we would get many coon photos and I sprayed raccoon urine at several of the sets just to make sure of attracting some of the bandits.

As stated earlier, I expected lots of raccoon photos. And we were not disappointed. Here are a few of the better ones. I am not a fan of the IR cameras. I would rather have the crisp photos from the flash cameras. However, we have some of each as the IRs do have their advantages. I created this set along a log hoping for a mink, but got coons and red squirrels instead. Still, an interesting photo and we found that my sardine oil and Vaseline concoction held up well for the week.

Beaver (6/11, Muller Field Station) |
We totaled 16 species (well, 17 if you count the bullfrog that was on a log when a bird triggered the camera) in all with half of them birds. I could not find my castor scent, so we only ended up with one beaver photo. But beaver pics are always nice. They are such a surprising looking animal that they look good at almost any angle. Look at the way the wet fur ripples on the right side of the animal.... just a cool photo!
Mink (6/11, Muller Field Station) |
We managed to document one other semi-aquatic mammal and like the beaver, only captured it in a single image. This is perhaps my favorite camera trapped mink. The pose is interesting and the face is fully visible. We didn't do a good enough job of keeping track of which SD card came from which set, so I am unsure what this set was baited with. Interestingly, when we ran the Wetlands Mammal class last fall we did not get a single photo of a mink but did get a photo of river otter. There have to be far more mink than otters so we were not expecting that result. It gave me a chance to talk to the students about the danger of relying on only one trial for your data (or your assumptions).
Identifying tracks (6/11, Muller Field Station) |
When the camera trapping was done, Sasha took over and presented some basics on tracks, trails and animal feet. She started with a PowerPoint and then a description of how to use the Track Finder book. Once that was over, we went out to the picnic tables and practiced identifying tracks and trails in containers of sand. Sasha used the rubber track replicas from Acorn Nauralists to make the imprints. Everyone seemed to enjoy the challenge!
Nice mink shot!
ReplyDeleteI have never gotten a really good mink shot like that (and I've tried like crazy to get good mink pics).
Well done, JVN!
Thanks! But I would gladly trade you this one for those river otter photos you posted recently... :)
