Margaret Truman, daughter of Harry S. Truman, published a book titled "White House Pets" in which she gave some details of Poll.

Andrew Jackson and his family, including his wife Rachel and her parrot Poor Poll, lived at "The Hermitage" in Nashville, Tennessee. Shortly after his election and his inevitable move to Washington Rachel died of a heart attack. I don't know if it's likely that Rachel and Poor Poll would have moved to Washington with Jackson but as things turned out Poll remained in Nashville.

Jackson often wrote home, and Truman notes that "One of his concerns was the welfare of Poor Poll, Rachel's pet parrot. William Donelson was the custodian of the parrot, and after one of the President's departures from "The Hermitage," he wrote to him, "Poor Poll is doing well. She is as fat and saucy as ever. From her continued good health, I think she will live to be an old bird".

Jackson continued to ask after Poor Poll and, shortly into his second term, wrote to Donelson "My dear Sir: Write me on receipt of this and let me know how your dear little Elizabeth is and whether Poor Poll, favorite bird of my dear wife is still living".

Truman doesn't detail a reply to that question but clearly Poor Poll remained in fine form because in her account of Jackson's funeral at "The Hermitage" she says "Poor Poll distinguished herself by introducing an element of the grotesque into the solemnity of the funeral services. She suddenly startled the assembled mourners by bursting into a loud torrent of profanity that made it necessary to suspend proceedings until her perch could be removed from the upper front portico to a more remote point".

Truman says no more of Poor Poll but it seems likely that any extreme end would have been thought worthy of account. It's to be hoped that foul-mouthed Poor Poll whittled out her days in fat happiness just as Jackson was promised she would.
