The smart deer hunter is always observing: Why do most of the bucks travel E-W in a patch of woods…why do does and fawns like a particular corner of a plot…why do deer flock to mineral licks after a heavy rain?
We’ve had a lot of heavy rain this summer, and an hour or so after each rain ends (no matter the time of day) my Spartan Camera app blows up with images of deer with their heads stuck in water-filled mineral holes. Must be something to it, so I reached out to biologists and mineral experts, most of whom had observed the same thing.
While we’re not sure why this occurs, we theorize that heavy rain roils a mineral site, pulling certain minerals off the soil and suspending them in water, where deer can “lick” them easily. As the water recedes, suspended minerals settle on the topsoil, again easily consumed by the deer. Water also causes leaching of the minerals, and perhaps that’s a factor.
Anyhow, check your cameras after a rain and see what you’ve got.
