I've run across a couple of mentions about the Ivory-billed Woodpecker that I want to offer for your perusal.
The first is from a website called Penn Live.
The U.S. Fish and Wildlife Service suggested declaring the bird extinct in September of 2021.

In that, they mentioned a National Aviary, which I found the following search results re: the species on their website.
You searched for ivory-billed woodpecker - National Aviary
It is not my intent to support or detract from anyone's position on this. Just an offer of information.
