I’d like to remind everyone that a photo of a nestling Kaua’i ō’ō exist and should give a BIG thank you to John Sincock who also has an unpublished paper about the ō’ō and his trips to Alaka’i swamp. This is the only known photograph of a nestling ō’ō. You can find this photo on the birds of the world website (linked in citation)

I hope the rest of his photos are out there somewhere. I was super lucky to be able to find his unpublished paper as well as some memos (shout out to Daniel Lewis who was able to send me the memos AND wrote about sincock and the ō’ō in his book Belonging on an Island : Birds, Extinction and Evolution in Hawai’i)
