These are test notes from a US company by Arcatech Systems that supplies currency handling equipment and not a product of any mint. The paper isn't same as it is lighter everyday kind of bond. I got a set of these from a very esteemed member of the forum.
The South American Rock Cock? is on the $1, I believe a species of Tanager $5, Scarlet Ibis $10, Black capped Chickadee $20, Mot-mot $50, I think is a Ruby-Throated Hummingbird $100. Most actual notes usually have the scientific name on it somewhere. These just don’t.
But I just love Bird notes. "Laus Deo"
