Barking Deer are generally solitary mammals and rarely seen in groups, except when it’s a courting couple. The male Barking Deer are highly territorial and put their short antlers and tusks to good use during fights.
Here’s a collection of images taken with the D300 with the 300mm f2.8 lens combination. The 300mm f2.8 with the 2x TC has been used in some of the images. The first and last images are of a female Barking Deer and the rest are of the Male.
