The Fallow Deer

So today I was out with a group of friends in a local estate near Plympton. The owner was there and while we were talking, he told us to just stop and listen for a second. So listen we did. Behind the bushes and the trees, we heard grunting. This grunting was the sound of Fallow deer. Apparently there are around 100 Fallow deer in the area, and for this 2 week period, its mating season. The sound we heard was a rare one, it was the sound of the buck’s grunting and thrashing around in the ferns. Why do they do this? Apparently, they try and make as much noise as possible, so they sound big and scary, so mates will be attracted to them. The louder they are, the more likely that they will find a mate. I found this quite interesting, I thought you guys might too. I wouldn’t try and go up against a Fallow deer at this time of year, you are likely to lose. Lots and lots of testosterone flowing.

As an interesting side note about Fallow deer, they are the only British deer to have palmate antlers, so they have that bit in between the horns, like frogs feet.
