Over the years I have closely observed some raccoons and a physical biological trait at least I know the males for sure exhibit. I am sure the females do this as well. However they are not as easily viewed for this observation due to their physical development which is hidden from easy examination view..
During the mating/rut time frame the males will drip small droplets of urine constantly from their baculum penile extension area. It runs down the fine hair extensions at the end of their baculum area and collects at the end sheath hair tips. Due to their low body profile and the hair extensions these droplets are easily deposited upon the grasses, ground and leaf clutter as they walk.
I have also observed them frequently rub their anal rectum area upon edges and corners of objects of a convenient height ever so briefly after toileting, eating or finding something that seems to interest them. I had to watch this behavior closely over time to see it and to understand what I was observing. Over time it was quite obvious in all animals observed. They were apparently using their anal gland and residual fecal deposits left on the rectum to deposit a slight amount of scent. Interesting behavior to see.
Acting very similar to the function of a deer scape dripper. I can only assume the multiple purposes of this constant dripping of urine for scent trailing back to their den site, following each others movements, keeping track of siblings or finding or trailing in heat females to name a few of the urine scent trail purposes. The anal rub deposit is just another way of marking and leaving more residual scent then just the urine alone.
Stands to reason. If you examine the anal area of a coon it is generally quite large. It also has wrinkles that hold traces of feces and anal gland excretions that are constantly released with each bowel movement. This scent most likely ferments becoming stronger over time in these skin wrinkles as bacteria develops in this waste build up area.
I have found little coon urine dribbled around a set can help promote more interest and more time at the set. Just like with many other animals urine and feces are the messages left, found and interpreted by other animals in their travels. The time of year obviously determines the importance and function of the urine DNA scent trail. Raccoon behavior takes on a different trait later in the season and they can be very indifferent as is known to some lure and bait presentations.
A few drops of lovage oil and some good asafoetida tincture added to some good coon urine can make a decent in - heat blend to play with on your next late season trapline for coon.
A small sturdy stick about 6 > 8 inches in height hammered into the ground about 12-15" from a DP with a dab of coon gland lure and urine squirt on top can sure help to promote interest beyond lure and bait in the late season. This will entice that coon to something that it does naturally every night on its travels.
Just some food for thought at this time of year. Not sure why I haven't posted this before. Maybe I did and don't remember. If I did sorry for the memory lapse.
