Glad you brought this up. I was up at camp after Christmas this past year and there was one hanging around our camp. I went out with the bow the one evening and i saw her and i was going to harvest her until a buck chased her off but i shot one of the other doe that was with her and she had one of those $100 dcnr tags from pennstate in her ear. I would have harvested the collared doe if a shot presented itself.
When i called the number on the back they gave me a little history on the deer i harvested. they told me how they caught it, what area, and the date. The deer i harvested was captured about 1 mile from our camp in January (cant remember the date) of 2017 and i harvested her on December 30th of 2017. I told her about the radio collared deer and she said if i would have harvested her they would have given me the details of her travels ect... Pretty cool they will supply you with that information. This was in Cherry Springs.
I would have no problem shooting the deer with the radio collar, she is part of a study & harvesting of that deer would be a normal end to that doe & help with the information that is needed for the study.
I don't know if this is even a valid concern, but I guess my only concern would for me to somehow skew the study haha. I might feel guilty harvesting a deer that could live on and provide valuable data.
