The US Department of the Interior had to change the wording on the metal bands they used to tag migratory birds. Seems these bands used to have the address of the Washington Biological Survey abbreviated as "Wash. Biol. Surv." One day they received a letter from a hunter in Alabama:
Last week I shot one of your birds. It might have been a crow. I followed the cooking directions on the leg tag. Let me tell you, It was AWFUL!
The bands are now marked "Fish and Wildlife Service."
