I have heard that the popular Christmas song (the 12 days of Christmas) was actually written to teach the Roman Catholic faith during the persecution in England.
When I went to Kona, Hawaii, I heard this bird screeching every morning and noon.
I was finally able to identify it. It turns out that the British missed their partridge and so imported some to the beautiful Island of Hawaii.
The huge partridge on our neighbor's roof who serenaded the dawn and the noonday was indeed a descendant from Britain.
