I've had an inquiry from a poultry lover about the USDA's Game Bird Antiquities Preservation Act. He tells me it was adopted around the time of Woodrow Wilson's administration, in response to over-hunting of game birds such as the Passenger Pigeon, which had driven it to extinction. Other game birds, such as the Labrador Duck, Heath Hen and Great Auk had also disappeared.
I have never heard of this and don't find anything on search engines, but any information would be gratefully received.
Wild turkeys like the one pictured above, as painted by Arthur Schilling in 1943, have made a good recovery. Other game birds can recover, with management. Having regulations directed at that goal would make a big difference. Please contact me if you know anything about this regulation.
