Is the population still being augmented by human-reared birds? If not,
do you know what year that stopped?

The project began in the '80's and until 1993 all the birds were "hacked" or hand reared. Since 1993 the population had increased to the point where some portion of the birds were wild born and "out on their own". Most of these birds were tagged but not all of them and since 1993 wild birds (both tagged and untagged) have been free to migrate or not migrate. So since 1993 some of the Ontario Trumpeters have been wild born and others hand reared and some tagged and some not tagged.
