Interesting. Thanks for your comment. All I can say is that my experiences with deer (primarily mule deer) and pronghorns where I live (south-western Saskatchewan) is as I stated. I admittedly see more pronghorns than deer, but the deer I've seen would never let me get as close to them as I was to the leader of this herd. I was maybe 10-15 metres away. He was standing by the side of the grid road watching over his harem, as it were, and continued to do so for some minutes. I stopped the car and got out to take pictures and he didn't so much as bat an eyelash. I was able to get a few shots and then they all wandered slowly off. I've had even closer encounters with pronghorns.
Chihuahuan pronghorn (one of three subspecies found in my state of Arizona). These occur in southeast Arizona, while southwest has Sonoran and north-central has American. As I stated earlier they are very skittish and as soon as they saw me walking along the highway (quite a distance away) they started running. This is Highway 82 near Sonoita, Arizona.
5D3 with 100-400 ii (at 400) and 1.4x ii extender (for a total of 560mm).
I finally got around to buying some salt licks and so far I've got a female moose and a foursome of white-tailed deer visiting. The deer are more interested in the bird feed it seems, especially the corn.
Great pics everyone! We are so fortunate to be able to come here and see pictures taken by people who are better able to take pictures than we can. Wether by skill or location. I find them to be inspiring.
