This deer is part of a study they are doing out there to determine why they are seeing fewer fawns each year. She didn't seem to mind the collar.
This is the same deer. I thought I would paint her...mostly because I had too slow of a shutter speed on this first shot, but I didn't want to throw it away.
A little more info about the program ...

Deer Study at the Rocky Mountain Arsenal National Widlife Refuge
Beginning this spring, biologists at RMA will be trapping and darting Mule and White-tailed Deer as part of an on-going study to determine why the deer herds are producing fewer fawns.
“In the late 90’s we noticed that fewer fawns were showing up in our annual fall surveys,” says biologist Sherry Skipper, who heads up the study. … We have a fence around RMA that prevents deer from getting in or out. And there is currently no hunting on the refuge.” Skipper goes on to say that the scarcity of fawns may be due to several reasons. Some reason may be nutritional deficiencies, the population has aged because older deer have survived longer without hunting, the coyote population has grown and is preying more on young fawns or the recent years of drought have taken its toll on young fawns or altered the vegetation so that fawns are more vulnerable.
“These, or any combination, are all reasonable explanations,” says Eric Stone, another biologist working on the project. “What we need to do is to find out if the does are pregnant. Then follow them until they give birth to fawns. And then follow the fawns to determine if they survive and what the causes of mortality are.” Skipper and Stone hope that by tracking the deer with radio-transmitters they can eventually find out what is causing fewer fawns to survive and whether intervention is needed.
So if you see a deer wearing a collar, now you will know it is part of an investigation. Like a detective story, this one may not be solved until the end of the book. But the collar is a means of collecting the clues we need to solve the RMA deer mystery.
