black tail with ear tag?

[Sakko300wsm]

Never seen a black tail with ear tags around here - had a buck at my parents place yesterday with a green one? Idea?

They are trying to mark the remaining BT deer left.

Correct.  I think you can count them on one hand.   

If you want more info, you could email the WDFW Biologist, Eric Holman who runs all or most of the BT studies.  He always answers email.

This is what i got back from the local bioligist

These deer would absolutely be huntable during the open season.  Our biologist is unaware of the tagged deer, so they would not be from any type of research project or anything.  Most likely the ear tags are a sign they were chemically immobilized at some point, but whether or not they are local or just made their way there from another area would be impossible for us to even guess without the numbers on their ear tags.  If harvested, those ear tags have a phone number on them with a tag number and instructions to call before consumption.  It is a safety measure to make sure a hunter can safely consume the animal, as it takes about 30 days for the drugs to completely leave the animals system and be safe for consumption.  Hope this helps.
