All the skunk issues we work on I have cameras out, not even the highest quality cams, but if setup right you can definitely identify males and females as their backsides get photographed!
Having run both video and still pic, the video is far better as the shots from the stills can be washed out sometimes, etc...due to proximity to entry points, and so on.
In the southwest we've been in full skunk romance season for at least a few weeks now and on camera have had as many as 5 at one entry point mix of males and females and homeowners report
the types of sounds that skunks make when "tussling" from experience we've had raising a few... The tussling seems to get some "gas" going though not usually full blown spray.
The folks where the odor comes and doesn't go away lately are definitely the dead skunk column where it was hit by a car, ran into the den and expired, or died of a variety of other causes both natural and man made...
Had some folks the other day who were convinced the skunk was alive though they stated it was sleeping between their shed and the wall of their property... When I asked about the location and that it was in the open the reply was, "but it keeps spraying so it must be alive!"
Ahhhh.... some conversations are fun! Trying to explain to folks that not only does a dead skunk often give off the burst of spray immediately upon dying, but that as decomposition occurs the breakdown keeps that odor rolling along....
Sure enough, dead skunk, far enough along that all the insects had found it, at least it was in the open, the crawlspace retrievals are not my favorite thing...
Believe we are going to have some very early litters this year with such a short winter and a very early summer as it seems we are skipping spring down here...
