Cooking instructions

The bands used to bear the address of the Washington Biological Survey, abbreviated: "Wash. Biol. Surv."
Until the agency received the this letter from an Arkansas camper:
"Dear Sirs: While camping last week I shot one of your birds. I think it was a crow. I followed the cooking instructions on the leg tag and I want to tell you, it was horrible."
The bands are now marked Fish and Wildlife Service.
